CYV15G0104TRB

Independent Clock HOTLink II™ Serializer and

Reclocking Deserializer

transfer of data over a variety of high-speed serial links

including SMPTE 292M and SMPTE 259M video applications.

Features

• Second-generation HOTLink technology

• Compliant to SMPTE 292M and SMPTE 259M video

standards

• Single channel video serializer plus single channel

video reclocking deserializer

It supports signaling rates in the range of 195 to 1500 Mbps

per serial link. The transmit and receive channels are

independent and can operate simultaneously at different

rates. The transmit channel accepts 10-bit parallel characters

in an Input Register and converts them to serial data. The

receive channel accepts serial data and converts it to 10-bit

parallel characters and presents these characters to an Output

retransmitted through the reclocker serial outputs. Figure 1

illustrates typical connections between independent video co-

processors and corresponding CYV15G0104TRB chips.

— 195- to 1500-Mbps serial data signaling rate

— Simultaneous operation at different signaling rates

• Supports reception of either 1.485 or 1.485/1.001 Gbps

data rate with the same training clock

• Internal phase-locked loops (PLLs) with no external

PLL components

• Supports half-rate and full-rate clocking

• Selectable differential PECL-compatible serial inputs

— Internal DC-restoration

The CYV15G0104TRB satisfies the SMPTE 259M and

SMPTE 292M compliance as per SMPTE EG34-1999 Patho-

logical Test Requirements.

HOTLink

device,

the

CYV15G0104TRB extends the HOTLink family with enhanced

levels of integration and faster data rates, while maintaining

serial-link compatibility (data and BIST) with other HOTLink

devices. The transmit (TX) channel of the CYV15G0104TRB

HOTLink II device accepts scrambled 10-bit transmission

characters. These characters are serialized and output from

dual Positive ECL (PECL) compatible differential trans-

mission-line drivers at a bit-rate of either 10- or 20-times the

input reference clock for that channel.

• Redundant differential PECL-compatible serial outputs

— No external bias resistors required

— Internal source termination

— Signaling-rate controlled edge-rates

• Synchronous LVTTL parallel interface

• JTAG boundary scan

• Built-In Self-Test (BIST) for at-speed link testing

• Link Quality Indicator

The receive (RX) channel of the CYV15G0104TRB HOTLink

II device accepts a serial bit-stream from one of two selectable

PECL-compatible differential line receivers, and using a

completely integrated Clock and Data Recovery PLL, recovers

the timing information necessary for data reconstruction. The

recovered bit-stream is reclocked and retransmitted through

the reclocker serial outputs. Also, the recovered serial data is

deserialized and presented to the destination host system.

—Analog signal detect

—Digital signal detect

• Low-power 1.8W @ 3.3V typical

• Single 3.3V supply

• Thermally enhanced BGA

• Pb-Free package option available

• 0.25µ BiCMOS technology

The transmit and receive channels contain an independent

BIST pattern generator and checker, respectively. This BIST

hardware allows at-speed testing of the high-speed serial data

paths in each transmit and receive section, and across the

interconnecting links.

TXDB[9:0]

TXERRB

transmit interface clock. The transmit interface clock is selected by the TXCKSELB latch

via the device configuration interface.

TXERRB is also asserted HIGH, when any of the following conditions is true:

REFCLKB±

• The TXPLL is powered down. This occurs when TOE2B and TOE1B are both disabled

by setting TOE2B = 0 and TOE1B = 0.

• The absence of the REFCLKB± signal.

Transmit Path Clock Signals

REFCLKB±

Differential LVPECL Reference Clock. REFCLKB± clock inputs are used as the timing reference for the

or single-ended

transmit PLL. This input clock may also be selected to clock the transmit parallel interface.

When driven by a single-ended LVCMOS or LVTTL clock source, connect the clock source

to either the true or complement REFCLKB input, and leave the alternate REFCLKB input

open (floating). When driven by an LVPECL clock source, the clock must be a differential

clock, using both inputs.

LVTTL input clock

TXCLKB

LVTTL Clock Input,

internal pull-down

Transmit Path Input Clock. When configuration latch TXCKSELB = 0, the associated

TXCLKB input is selected as the character-rate input clock for the TXDB[9:0] input. In this

mode, the TXCLKB input must be frequency-coherent to its TXCLKOB output clock, but

may be offset in phase by any amount. Once initialized, TXCLKB is allowed to drift in

phase by as much as ±180 degrees. If the input phase of TXCLKB drifts beyond the

handling capacity of the Phase Align Buffer, TXERRB is asserted to indicate the loss of

data, and remains asserted until the Phase Align Buffer is initialized. The phase of

TXCLKB relative to REFCLKB± is initialized when the configuration latch PABRSTB is

written as 0. When TXERRB is deasserted, the Phase Align Buffer is initialized and input

characters are correctly captured.

TXCLKOB

LVTTL Output

Transmit Clock Output. TXCLKOB output clock is synthesized by the transmit PLL and

operates synchronous to the internal transmit character clock. TXCLKOB operates at

either the same frequency as REFCLKB± (TXRATEB = 0), or at twice the frequency of

REFCLKB± (TXRATEB = 1). The transmit clock outputs have no fixed phase relationship

to REFCLKB±.

Receive Path Data and Status Signals

RXDA[9:0]

LVTTL Output,

synchronous to the

RXCLKA ± output

Parallel Data Output. RXDA[9:0] parallel data outputs change relative to the receive

interface clock. If RXCLKA± is a full-rate clock, the RXCLKA± clock outputs are comple-

mentary clocks operating at the character rate. The RXDA[9:0] outputs for the associated

receive channels follow rising edge of RXCLKA+ or falling edge of RXCLKA–. If RXCLKA±

is a half-rate clock, the RXCLKA± clock outputs are complementary clocks operating at

half the character rate. The RXDA[9:0] outputs for the associated receive channels follow

both the falling and rising edges of the associated RXCLKA± clock outputs.

When BIST is enabled on the receive channel, the BIST status is presented on the

RXDA[1:0] and BISTSTA outputs. See Table 6 for each status reported by the BIST state

machine. Also, while BIST is enabled, the RXDA[9:2] outputs should be ignored.

Notes:

2. When REFCLKB± is configured for half-rate operation, these inputs are sampled relative to both the rising and falling edges of the associated REFCLKB±.

3. When REFCLKB± is configured for half-rate operation, this output is presented relative to both the rising and falling edges of the associated REFCLKB±.

the frequency detector (Range Controller) of the receive PLL to reduce PLL acquisition

time.

In the presence of valid serial data, the recovered clock output of the receive CDR PLL

(RXCLKA±) has no frequency or phase relationship with TRGCLKA±.

When driven by a single-ended LVCMOS or LVTTL clock source, connect the clock source

to either the true or complement TRGCLKA input, and leave the alternate TRGCLKA input

open (floating). When driven by an LVPECL clock source, the clock must be a differential

clock, using both inputs.

RXCLKA±

RECLKOA

LVTTL Output Clock Receive Clock Output. RXCLKA± is the receive interface clock used to control timing of

the RXDA[9:0] parallel outputs. These true and complement clocks are used to control

timing of data output transfers. These clocks are output continuously at either the half-

character rate (1/20 the serial bit-rate) or character rate (1/10 the serial bit-rate) of the

data being received, as selected by RXRATEA.

LVTTL Output

Reclocker Clock Output. RECLKOA output clock is synthesized by the reclocker output

PLL and operates synchronous to the internal recovered character clock. RECLKOA

operates at either the same frequency as RXCLKA± (RXRATEA = 0), or at twice the

frequency of RXCLKA± (RXRATEA = 1).The reclocker clock outputs have no fixed phase

relationship to RXCLKA±.

Device Control Signals

RESET

LVTTL Input,

asynchronous,

internal pull-up

Asynchronous Device Reset. RESET initializes all state machines, counters, and

configuration latches in the device to a known state. RESET must be asserted LOW for a

minimum pulse width. When the reset is removed, all state machines, counters and config-

uration latches are at an initial state. See Table 4 for the initialize values of the device

configuration latches.

LDTDEN

LVTTL Input,

internal pull-up

Level Detect Transition Density Enable. When LDTDEN is HIGH, the Signal Level

Detector, Range Controller, and Transition Density Detector are all enabled to determine

if the RXPLL tracks TRGCLKA± or the selected input serial data stream. If the Signal Level

Detector, Range Controller, or Transition Density Detector are out of their respective limits

while LDTDEN is HIGH, the RXPLL locks to TRGCLKA± until such a time they become

valid. SDASEL[2..1]A[1:0] is used to configure the trip level of the Signal Level Detector.

The Transition Density Detector limit is one transition in every 60 consecutive bits. When

LDTDEN is LOW, only the Range Controller is used to determine if the RXPLL tracks

TRGCLKA± or the selected input serial data stream. it is recommended to set LDTDEN

= HIGH.

ULCA

LVTTL Input,

internal pull-up

Use Local Clock. When ULCA is LOW, the RXPLL is forced to lock to TRGCLKA± instead

of the received serial data stream. While ULCA is LOW, the link fault indicator LFIA is

LOW indicating a link fault.

When ULCA is HIGH, the RXPLL performs Clock and Data Recovery functions on the

input data streams. This function is used in applications in which a stable RXCLKA± is

needed. In cases when there is an absence of valid data transitions for a long period of

time, or the high-gain differential serial inputs (INA±) are left floating, there may be brief

frequency excursions of the RXCLKA± outputs from TRGCLKA±.

CYV15G0104TRB HOTLink II Operation

CYV15G0104TRB Transmit Data Path

The CYV15G0104TRB is a highly configurable, independent

clocking device designed to support reliable transfer of large

quantities of digital video data, using high-speed serial links

from multiple sources to multiple destinations.

Input Register

The parallel input bus TXDB[9:0] can be clocked in using

TXCLKB (TXCKSELB = 0) or REFCLKB (TXCKSELB = 1).

Phase-Align Buffer

Table 1. Operating Speed Settings

Data from the Input Register is passed to the Phase-Align

Buffer, when the TXDB[9:0] input register is clocked using

TXCLKBA (TXCKSELB = 0) or when REFCLKB is a half-rate

clock (TXCKSELB = 1 and TXRATEB = 1). When the

TXDB[9:0] input register is clocked using REFCLKB±

(TXCKSELA = 1) and REFCLKB± is a full-rate clock

(TXRATEB = 0), the associated Phase Alignment Buffer in the

transmit path is bypassed. These buffers are used to absorb

clock phase differences between the TXCLKB input clock and

the internal character clock for that channel.

Once initialized, TXCLKB is allowed to drift in phase as much

as ±180 degrees. If the input phase of TXCLKB drifts beyond

the handling capacity of the Phase Align Buffer, TXERRB is

asserted to indicate the loss of data, and remains asserted

until the Phase Align Buffer is initialized. The phase of

TXCLKB relative to its internal character rate clock is initialized

when the configuration latch PABRSTB is written as 0. When

the associated TXERRB is deasserted, the Phase Align Buffer

is initialized and input characters are correctly captured.

80–150

The REFCLKB± inputs are differential inputs with each input

internally biased to 1.4V. If the REFCLKB+ input is connected

to a TTL, LVTTL, or LVCMOS clock source, the input signal is

recognized when it passes through the internally biased

reference point. When driven by a single-ended TTL, LVTTL,

or LVCMOS clock source, connect the clock source to either

the true or complement REFCLKB input, and leave the

alternate REFCLKB input open (floating).

If the phase offset, between the initialized location of the input

clock and REFCLKB, exceeds the skew handling capabilities

of the Phase-Align Buffer, an error is reported on that

channel’s TXERRB output. This output indicates an error

continuously until the Phase-Align Buffer for that channel is

reset. While the error remains active, the transmitter for that

channel outputs a continuous “1001111000” character to

indicate to the remote receiver that an error condition is

present in the link.

When both the REFCLKB+ and REFCLKB– inputs are

connected, the clock source must be a differential clock. This

can either be a differential LVPECL clock that is DC-or

AC-coupled or a differential LVTTL or LVCMOS clock.

By connecting the REFCLKB– input to an external voltage

source, it is possible to adjust the reference point of the

REFCLKB+ input for alternate logic levels. When doing so, it

is necessary to ensure that the input differential crossing point

remains within the parametric range supported by the input.

Transmit BIST

The transmit channel contains an internal pattern generator

that can be used to validate both the link and device operation.

This generator is enabled by the TXBISTB latch via the device

configuration interface. When enabled, a register in the

transmit channel becomes a signature pattern generator by

logically converting to a Linear Feedback Shift Register

(LFSR). This LFSR generates a 511-character sequence. This

provides a predictable yet pseudo-random sequence that can

be matched to an identical LFSR in the attached Receiver(s).

Transmit Serial Output Drivers

The serial output interface drivers use differential Current

Mode Logic (CML) drivers to provide source-matched drivers

for 50Ω transmission lines. These drivers accept data from the

transmit shifter. These drivers have signal swings equivalent

to that of standard PECL drivers, and are capable of driving

AC-coupled optical modules or transmission lines.

Transmit Channels Enabled

A device reset (RESET sampled LOW) presets the BIST

Enable Latches to disable BIST on all channels.

Each driver can be enabled or disabled separately via the

device configuration interface.

All data present at the TXDB[9:0] inputs are ignored when

BIST is active on that channel.

When a driver is disabled via the configuration interface, it is

internally powered down to reduce device power. If both

transmit serial drivers are in this disabled state, the transmitter

internal logic for that channel is also powered down. A device

reset (RESET sampled LOW) disables all output drivers.

Transmit PLL Clock Multiplier

The Transmit PLL Clock Multiplier accepts a character-rate or

half-character-rate external clock at the REFCLKB± input, and

that clock is multiplied by 10 or 20 (as selected by TXRATEB)

to generate a bit-rate clock for use by the transmit shifter. It

also provides a character-rate clock used by the transmit

paths, and outputs this character rate clock as TXCLKOB.

Note. When the disabled transmit channel (i.e., both outputs

disabled) is re-enabled:

• the data on the transmit serial outputs may not meet all

timing specifications for up to 250 µs

• the state of the phase-align buffer cannot be guaranteed,

and a phase-align reset is required if the phase-align buffer

is used

The clock multiplier PLL can accept a REFCLKB± input

between 19.5 MHz and 150 MHz, however, this clock range is

limited by the operating mode of the CYV15G0104TRB clock

multiplier (TXRATEB) and by the level on the SPDSELB input.

SPDSELB is a 3-level select input that selects one of three

operating ranges for the serial data outputs of the transmit

channel. The operating serial signaling-rate and allowable

range of REFCLKB± frequencies are listed in Table 1.

Serial Line Receivers

Two differential Line Receivers, INA1± and INA2±, are

available on the receive channel for accepting serial data

streams. The active Serial Line Receiver is selected using the

receivers accommodates a wide range of signal termination

the center of the receiver’s common mode range, for AC-

coupled signals.

(RESET sampled LOW) disables all output drivers.

• limit unlocked frequency excursions of the CDR VCO when

there is no input data present at the selected Serial Line

Receiver.

The receive channel presents a 10-bit data signal (and a BIST

status signal when RXBISTA[1:0] = 10).

Regardless of the type of signal present, the CDR attempts to

recover a data stream from it. If the signaling rate of the

recovered data stream is outside the limits set by the range

control monitors, the CDR tracks TRGCLKA± instead of the

data stream. Once the CDR output (RXCLKA±) frequency

returns back close to the TRGCLKA± frequency, the CDR

input is switched back to the input data stream. If no data is

present at the selected line receiver, this switching behavior

may result in brief RXCLKA± frequency excursions from

TRGCLKA±. However, the validity of the input data stream is

Receive BIST Operation

The receiver channel contains an internal pattern checker that

can be used to validate both device and link operation. These

pattern checkers are enabled by the RXBISTA[1:0] latch via

the device configuration interface. When enabled, a register in

the receive channel becomes a signature pattern generator

and checker by logically converting to a Linear Feedback Shift

sequence. This provides a predictable yet pseudo-random

sequence that can be matched to an identical LFSR in the

attached Transmitter(s). When synchronized with the received

data stream, the Receiver checks each character from the

deserializer with each character generated by the LFSR and

indicates compare errors and BIST status at the RXDA[1:0]

and BISTSTA bits of the Output Register.

indicated by the LFIA output. The frequency of TRGCLKA± is

[24]

required to be within ±1500ppm

of the frequency of the

clock that drives the REFCLKB± input of the remote trans-

mitter to ensure a lock to the incoming data stream. This large

ppm tolerance allows the CDR PLL to reliably receive a 1.485

or 1.485/1.001 Gbps SMPTE HD-SDI data stream with a

constant TRGCLK frequency.

The BIST status bus {BISTSTA, RXDA[0], RXDA[1]} indicates

010b or 100b for one character period per BIST loop to

indicate loop completion. This status can be used to check test

pattern progress.

For systems using multiple or redundant connections, the

LFIA output can be used to select an alternate data stream.

When an LFIA indication is detected, external logic can toggle

selection of the INA1± and INA2± input through the INSELA

input. When a port switch takes place, it is necessary for the

receive PLL for that channel to reacquire the new serial

stream.

The specific status reported by the BIST state machine is listed

in Table 6. These same codes are reported on the receive

status outputs.

If the number of invalid characters received ever exceeds the

number of valid characters by 16, the receive BIST state

machine aborts the compare operations and resets the LFSR

to look for the start of the BIST sequence again.

Reclocker

The receive channel performs a reclocker function on the

incoming serial data. To do this, the Clock and Data Recovery

PLL first recovers the clock from the data. The data is retimed

by the recovered clock and then passed to an output register.

Also, the recovered character clock from the receive PLL is

passed to the reclocker output PLL which generates the bit

clock that is used to clock the retimed data into the output

differential serial outputs.

A device reset (RESET sampled LOW) presets the BIST

Enable Latches to disable BIST on all channels.

BIST Status State Machine

When a receive path is enabled to look for and compare the

received data stream with the BIST pattern, the {BISTSTA,

RXDA[1:0]} bits identify the present state of the BIST compare

operation.

Reclocker Serial Output Drivers

The BIST state machine has multiple states, as shown in

Figure 2 and Table 6. When the receive PLL detects an out-of-

lock condition, the BIST state is forced to the Start-of-BIST

state, regardless of the present state of the BIST state

machine. If the number of detected errors ever exceeds the

number of valid matches by greater than 16, the state machine

is forced to the WAIT_FOR_BIST state where it monitors the

receive path for the first character of the next BIST sequence.

The serial output interface drivers use differential Current

Mode Logic (CML) drivers to provide source-matched drivers

for 50Ω transmission lines. These drivers accept data from the

reclocker output register in the reclocker channel. These

drivers have signal swings equivalent to that of standard PECL

drivers, and are capable of driving AC-coupled optical

modules or transmission lines.

initialization value of the latches upon the assertion of RESET.

Table 5 shows how the latches are mapped in the device.

Each row in the Table 5 maps to a 7-bit latch bank. There are

6 such write-only latch banks. When WREN = 0, the logic value

in the DATA[6:0] is latched to the latch bank specified by the

values in ADDR[2:0]. The second column of Table 5 specifies

the channels associated with the corresponding latch bank.

For example, the first three latch banks (0,1 and 2) consist of

configuration bits for the reclocker channel A.

Latch Types

There are two types of latch banks: static (S) and dynamic (D).

Each channel is configured by 2 static and 1 dynamic latch

banks. The S type contain those settings that normally do not

change for a given application, whereas the D type controls

the settings that could change during the application's lifetime.

The first and second rows of each channel (address numbers

0, 1, 5, and 6) are the static control latches. The third row of

latches for each channel (address numbers 2 and 7) are the

dynamic control latches that are associated with enabling

dynamic functions within the device. Address numbers 3 and

4 are internal test registers.

Device Reset State

When the CYV15G0104TRB is reset by assertion of RESET,

all state machines, counters, and configuration latches in the

device are initialized to a reset state. See Table 4 for the

initialize values of the configuration latches.

Following a device reset, it is necessary to enable the transmit

and receive channels used for normal operation. This can be

done by sequencing the appropriate values on the device

configuration interface.

Static Latch Values

There are some latches in the table that have a static value

(i.e. 1, 0, or X). The latches that have a ‘1’ or ‘0’ must be

configured with their corresponding value each time that their

associated latch bank is configured. The latches that have an

‘X’ are don’t cares and can be configured with any value.

Device Configuration and Control Interface

The CYV15G0104TRB is highly configurable via the configu-

ration interface. The configuration interface allows the trans-

mitter and reclocker to be configured independently. Table 4

lists the configuration latches within the device including the

PABRSTB

Transmit Clock Phase Alignment Buffer Reset. The initialization value of the PABRSTB latch = 1. The

PABRSTB is used to re-center the Transmit Phase Align Buffer. When the configuration latch PABRSTB is

written as a 0, the phase of the TXCLKB input clock relative to REFCLKB+/- is initialized. PABRSTB is an

asynchronous input, but is sampled by each TXCLKB↑ to synchronize it to the internal clock domain.

PABRSTB is a self clearing latch. This eliminates the requirement of writing a 1 to complete the initialization

of the Phase Alignment Buffer.

Notes:

8. Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.

9. This is the minimum difference in voltage between the true and complement inputs required to ensure detection of a logic-1 or logic-0. A logic-1 exists when

the true (+) input is more positive than the complement (−) input. A logic-0 exists when the complement (−) input is more positive than true (+) input.

10. The common mode range defines the allowable range of REFCLKB+ and REFCLKB− when REFCLKB+ = REFCLKB−. This marks the zero-crossing between

the true and complement inputs as the signal switches between a logic-1 and a logic-0.

Notes:

11. The common mode range defines the allowable range of INPUT+ and INPUT− when INPUT+ = INPUT−. This marks the zero-crossing between the true and

complement inputs as the signal switches between a logic-1 and a logic-0.

12. Maximum I is measured with V = MAX,T = 25°C, with all channels and Serial Line Drivers enabled, sending a continuous alternating 01 pattern, and

outputs unloaded.

13. Typical I is measured under similar conditions except with V = 3.3V, T = 25°C,with all channels enabled and one Serial Line Driver per channel sending

a continuous alternating 01 pattern. The redundant outputs on each channel are powered down and the parallel outputs are unloaded.

14. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.

15. The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.

16. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.

Notes:

17. The ratio of rise time to falling time must not vary by greater than 2:1.

18. For a given operating frequency, neither rise or fall specification can be greater than 20% of the clock-cycle period or the data sheet maximum time.

19. All transmit AC timing parameters measured with 1ns typical rise time and fall time.

20. Parallel data output specifications are only valid if all outputs are loaded with similar DC and AC loads.

21. Receiver UI (Unit Interval) is calculated as 1/(f

* 20) (when TRGRATEA = 1) or 1/(f

* 10) (when TRGRATEA = 0). In an operating link this is equivalent to t .

TRG

22. The duty cycle specification is a simultaneous condition with the t

and t

parameters. This means that at faster character rates the REFCLKB± duty

REFH

REFL

cycle cannot be as large as 30%–70%.

Notes:

23. The duty cycle specification is a simultaneous condition with the t

and t

parameters. This means that at faster character rates the TRGCLKA± duty

TRGL

TRGH

cycle cannot be as large as 30%–70%.

24. TRGCLKA± has no phase or frequency relationship with the recovered clock(s) and only acts as a centering reference to reduce clock synchronization time.

TRGCLKA± must be within ±1500 PPM (±0.15%) of the transmitter PLL reference (REFCLK±) frequency. Although transmitting to a HOTLink II receiver channel

necessitates the frequency difference between the transmitter and receiver reference clocks to be within ±1500-PPM, the stability of the crystal needs to be

within the limits specified by the appropriate standard when transmitting to a remote receiver that is compliant to that standard.

25. While sending BIST data at the corresponding data rate, after 10,000 histogram hits, time referenced to REFCLKB± input.

26. Receiver input stream is BIST data from the transmit channel. This data is reclocked and output to a wide-bandwidth digital sampling oscilloscope. The

measurement was recorded after 10,000 histogram hits, time referenced to REFCLKB± of the transmit channel.
