The CYV15G0203TB Independent Clock Dual HOTLink II™
Serializer is a point-to-point or point-to-multipoint communications building block enabling transfer of data over a variety of
high-speed serial links including SMPTE 292M and SMPTE
259M video applications. It supports signaling rates in the
range of 195 to 1500 Mbps per serial link. The two channels
are independent and can simultaneously operate at different
rates. Each channel accepts 10-bit parallel characters in an
Input Register and converts them to serial data. Figure 1 illustrates typical connections between independent video
co-processors and corresponding CYV15G0203TB Serializer
and CYV15G0204RB Reclocking Deserializer chips.
The CYV15G0203TB satisfies the SMPTE-259M and
SMPTE-292M compliance as per SMPTE EG34-1999 Pathological Test Requirements.
As
a
second-generation
HOTLink
device,
the
CYV15G0203TB 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. Each channel of the CYV15G0203TB Dual HOTLink
II device accepts scrambled 10-bit transmission characters.
These characters are serialized and output from dual Positive
ECL (PECL) compatible differential transmission-line drivers
at a bit-rate of either 10- or 20-times the input reference clock
for that channel.
— Internal source termination
Synchronous LVTTL parallel interface
JTAG boundary scan
Built-In Self-Test (BIST) for at-speed link testing
Low-power 1.4W @ 3.3V typical
Single 3.3V supply
Thermally enhanced BGA
Pb-Free package option available
0.25μ BiCMOS technology
Each channel contains an independent BIST pattern
generator. This BIST hardware allows at-speed testing of the
high-speed serial data paths in each transmit section of this
device, each receive section of a connected HOTLink II
device, and across the interconnecting links.
The CYV15G0203TB is ideal for SMPTE applications where
different data rates and serial interface standards are
necessary for each channel. Some applications include
multi-format routers, switchers, format converters, and
cameras.

TXDB[9:0]
LVTTL Input,
synchronous,

associated
TXCLKx↑ or

Transmit Data Inputs. TXDx[9:0] data inputs are captured on the rising edge of the
transmit interface clock. The transmit interface clock is selected by the TXCKSELx
latch via the device configuration interface.

LVTTL Output,

or return of REFCLKx±
Transmit Path Error. TXERRx is asserted HIGH to indicate detection of a transmit
Phase-Align Buffer underflow or overflow. If an underflow or overflow condition is
detected, TXERRx, for the channel in error, is asserted HIGH and remains asserted
until the transmit Phase-Align Buffer is re-centered with the PABRSTx latch via the
device configuration interface. When TXBISTx = 0, the BIST progress is presented
on the associated TXERRx output. The TXERRx signal pulses HIGH for one
transmit-character clock period to indicate a pass through the BIST sequence once
every 511 character times.
TXERRx is also asserted HIGH, when any of the following conditions is true:
• The TXPLL for the associated channel is powered down. This occurs when OE2x
and OE1x for a given channel are both disabled by setting OE2x = 0 and OE1x = 0.
• The absence of the REFCLKx± signal.
Transmit Path Clock Signals
REFCLKA±
REFCLKB±
Differential LVPECL or Reference Clock. REFCLKx± clock inputs are used as the timing references for the
single-ended
associated transmit PLL. These input clocks may also be selected to clock the
LVTTL input clock
transmit parallel interface. When driven by a single-ended LVCMOS or LVTTL clock
source, connect the clock source to either the true or complement REFCLKx input,
and leave the alternate REFCLKx input open (floating). When driven by an LVPECL
clock source, the clock must be a differential clock, using both inputs.
TXCLKA
TXCLKB
LVTTL Clock Input,
internal pull-down
Transmit Path Input Clock. When configuration latch TXCKSELx = 0, the associated
TXCLKx input is selected as the character-rate input clock for the TXDB[9:0] input. In
this mode, the TXCLKx input must be frequency-coherent to its associated TXCLKOx
output clock, but may be offset in phase by any amount. Once initialized, TXCLKx is
allowed to drift in phase as much as ±180 degrees. If the input phase of TXCLKx drifts
beyond the handling capacity of the Phase Align Buffer, TXERRx is asserted to
indicate the loss of data, and remains asserted until the Phase Align Buffer is
initialized. The phase of the TXCLKx input clock relative to its associated REFCLKx±
is initialized when the configuration latch PABRSTx is written as 0. When the
associated TXERRx is deasserted, the Phase Align Buffer is initialized and input
characters are correctly captured.
TXCLKOA
TXCLKOB
LVTTL Output
Transmit Clock Output. TXCLKOx output clock is synthesized by each channel’s
transmit PLL and operates synchronous to the internal transmit character clock.
TXCLKOx operates at either the same frequency as REFCLKx± (TXRATEx = 0), or
at twice the frequency of REFCLKx± (TXRATEx = 1). The transmit clock outputs have
no fixed phase relationship to REFCLKx±.
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 configuration latches are at an initial state. As per the JTAG specifications the
device RESET cannot reset the JTAG controller. Therefore, the JTAG controller has
to be reset separately. Refer to “JTAG Support” on page 10 for the methods to reset
the JTAG state machine. See Table 2 on page 10 for the initialize values of the device
configuration latches.
Notes
2. When REFCLKx± is configured for half-rate operation, these inputs are sampled relative to both the rising and falling edges of the associated REFCLKx±.
3. When REFCLKx± is configured for half-rate operation, these outputs are presented relative to both the rising and falling edges of the associated REFCLKx±.

implemented by not connecting the input (left floating), which allows it to self bias to the proper level.

CYV15G0203TB HOTLink II Operation
The CYV15G0203TB is a highly configurable, independent
clocking, dual-channel serializer, designed to support reliable
transfer of large quantities of digital video data, using
high-speed serial links from multiple sources to multiple destinations. This device supports two 10-bit channels.
CYV15G0203TB Transmit Data Path
Input Register
The parallel input bus TXDx[9:0] can be clocked in using
TXCLKx (TXCKSELx = 0) or REFCLKx (TXCKSELx = 1).
Phase-Align Buffer
Data from each Input Register is passed to the associated
Phase-Align Buffer, when the TXDx[9:0] input registers are
clocked using TXCLKx (TXCKSELx = 0 and TXRATEx = 0).
When the TXDx[9:0] input registers are clocked using
REFCLKx± (TXCKSELx = 1) and REFCLKx± is a full-rate
clock, the associated Phase Alignment Buffer in the transmit
path is bypassed. These buffers are used to absorb clock
phase differences between the TXCLKx input clock and the
internal character clock for that channel.
Once initialized, TXCLKx is allowed to drift in phase as much
as ±180 degrees. If the input phase of TXCLKx drifts beyond
the handling capacity of the Phase Align Buffer, TXERRx is
asserted to indicate the loss of data, and remains asserted
until the Phase Align Buffer is initialized. The phase of the
TXCLKx relative to its associated internal character rate clock
is initialized when the configuration latch PABRSTx is written
as 0. When the associated TXERRx is deasserted, the Phase
Align Buffer is initialized and input characters are correctly
captured.
If the phase offset, between the initialized location of the input
clock and REFCLKx, exceeds the skew handling capabilities
of the Phase-Align Buffer, an error is reported on that
channel’s TXERRx output. This output indicates an error
continuously until the Phase-Align Buffer for that channel is
Document #: 38-02105 Rev. *C
reset. While the error remains active, the transmitter for that
channel outputs a continuous “1001111000” character (LSB
first) to indicate to the remote receiver that an error condition
is present in the link.
Transmit BIST
Each channel contains an internal pattern generator that can
be used to validate both the link and device operation. These
generators are enabled by the associated TXBISTx latch via
the device configuration interface. When enabled, a register in
the associated 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).
A device reset (RESET sampled LOW) presets the BIST
Enable Latches to disable BIST on both channels.
All data present at the associated TXDx[9:0] inputs are ignored
when BIST is active on that channel.
Transmit PLL Clock Multiplier
Each Transmit PLL Clock Multiplier accepts a character-rate
or half-character-rate external clock at the associated
REFCLKx± input, and that clock is multiplied by 10 or 20 (as
selected by TXRATEx) 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
TXCLKOx.
Each clock multiplier PLL can accept a REFCLKx± input
between 19.5 MHz and 150 MHz, however, this clock range is
limited by the operating mode of the CYV15G0203TB clock
multiplier (TXRATEx) and by the level on the associated
SPDSELx input.
SPDSELx are 3-level select[4] inputs that select one of three
operating ranges for the serial data outputs and inputs of the
associated channel. The serial signaling-rate and allowable
range of REFCLKx± frequencies are listed in Table 1 on page
9.

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 REFCLKx input, and leave the
alternate REFCLKx input open (floating).
When both the REFCLKx+ and REFCLKx– 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 REFCLKx– input to an external voltage
source, it is possible to adjust the reference point of the
REFCLKx+ 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.
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, which shifts the data out LSB first. 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
Each driver can be enabled or disabled separately via the
device configuration interface.
When a driver is disabled via the configuration interface, it is
internally powered down to reduce device power. If both serial
Document #: 38-02105 Rev. *C
drivers for a channel are in this disabled state, the associated
internal logic for that channel is also powered down. A device
reset (RESET sampled LOW) disables all output drivers.
Note. When a disabled channel (i.e., both outputs disabled) is
re-enabled:
• data on the 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
Device Configuration and Control Interface
The CYV15G0203TB is highly configurable via the configuration interface. The configuration interface allows each
channel to be configured independently. Table 2 on page 10
lists the configuration latches within the device including the
initialization value of the latches upon the assertion of RESET.
Table 3 on page 11 shows how the latches are mapped in the
device. Each row in the Table 3 maps to a 4-bit latch bank.
There are 6 such write-only latch banks. When WREN = 0, the
logic value in the DATA[3:0] is latched to the latch bank
specified by the values in ADDR[2:0]. The second column of
Table 3 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 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. Address numbers 3 and 4 are internal
test registers.
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.

Table 2. Device Configuration and Control Latch Descriptions
Name
Signal Description
TXCKSELA
TXCKSELB
Transmit Clock Select. The initialization value of the TXCKSELx latch = 1. TXCKSELx selects the clock
source used to write data into the Transmit Input Register. When TXCKSELx = 1, the associated input
register TXDx[9:0] is clocked by REFCLKx↑. In this mode, the phase alignment buffer is bypassed. When
TXCKSELx = 0, the associated TXCLKx↑ is used to clock in the input register TXDx[9:0].
TXRATEA
TXRATEB
Transmit PLL Clock Rate Select. The initialization value of the TXRATEx latch = 0. TXRATEx is used
to select the clock multiplier for the Transmit PLL. When TXRATEx = 0, each transmit PLL multiples the
associated REFCLKx± input by 10 to generate the serial bit-rate clock. When TXRATEx = 0, the
TXCLKOx output clocks are full-rate clocks and follow the frequency and duty cycle of the associated
REFCLKx± input. When TXRATEx = 1, each Transmit PLL multiplies the associated REFCLKx± input by
20 to generate the serial bit-rate clock. When TXRATEx = 1, the TXCLKOx output clocks are twice the
frequency rate of the REFCLKx± input. When TXCLKSELx = 1 and TXRATEx = 1, the Transmit Data
Inputs are captured using both the rising and falling edges of REFCLKx. TXRATEx = 1 and SPDSELx =
LOW, is an invalid state and this combination is reserved.
TXBISTA
TXBISTB
Transmit Bist Disabled. The initialization value of the TXBISTx latch = 1. TXBISTx selects if the transmit
BIST is disabled or enabled. When TXBISTx = 1, the transmit BIST function is disabled. When
TXBISTx = 0, the transmit BIST function is enabled.
OE2A
OE2B
Secondary Differential Serial Data Output Driver Enable. The initialization value of the OE2x latch =
0. OE2x selects if the OUT2x± secondary differential output drivers are enabled or disabled. When OE2x
= 1, the associated serial data output driver is enabled allowing data to be transmitted from the transmit
shifter. When OE2x = 0, the associated serial data output driver is disabled. When a driver is disabled via
the configuration interface, it is internally powered down to reduce device power. If both serial drivers for
a channel are in this disabled state, the associated internal logic for that channel is also powered down.
A device reset (RESET sampled LOW) disables all output drivers.
OE1A
OE1B
Primary Differential Serial Data Output Driver Enable. The initialization value of the OE1x latch = 0.
OE1x selects if the OUT1x± primary differential output drivers are enabled or disabled. When OE1x = 1,
the associated serial data output driver is enabled allowing data to be transmitted from the transmit shifter.
When OE1x = 0, the associated serial data output driver is disabled. When a driver is disabled via the
configuration interface, it is internally powered down to reduce device power. If both serial drivers for a
channel are in this disabled state, the associated internal logic for that channel is also powered down.
A device reset (RESET sampled LOW) disables all output drivers.
PABRSTA
PABRSTB
Transmit Clock Phase Alignment Buffer Reset. The initialization value of the PABRSTx latch = 1. The
PABRSTx is used to re-center the Transmit Phase Align Buffer. When the configuration latch PABRSTx
is written as a 0, the phase of the TXCLKx input clock relative to its associated REFCLKx+/- is initialized.
PABRST is an asynchronous input, but is sampled by each TXCLKx↑ to synchronize it to the internal
clock domain. PABRSTx is a self clearing latch. This eliminates the requirement of writing a 1 to complete
the initialization of the Phase Alignment Buffer.
Device Configuration Strategy
The following is a series of ordered events needed to load the
configuration latches on a per channel basis:
1. Pulse RESET Low after device power-up. This operation
resets both channels. Initialize the JTAG state machine to
its reset state as detailed in the JTAG Support section.
2. Set the static latch banks for the target channel.
3. Set the dynamic bank of latches for the target channel.
Enable the output drivers. [Required step.]
4. Reset the Phase Alignment Buffer for the target channel.
[Optional if phase align buffer is bypassed.]
JTAG Support
The CYV15G0203TB contains a JTAG port to allow system
level diagnosis of device interconnect. Of the available JTAG
modes, boundary scan, and bypass are supported. This
capability is present only on the LVTTL inputs and outputs and
the REFCLKx± clock input. The high-speed serial inputs and
Document #: 38-02105 Rev. *C
outputs are not part of the JTAG test chain. To ensure valid
device operation after power-up (including non-JTAG
operation), the JTAG state machine should also be initialized
to a reset state. This should be done in addition to the device
reset (using RESET). The JTAG state machine can be
initialized using TRST (asserting it LOW and de-asserting it or
leaving it asserted), or by asserting TMS HIGH for at least 5
consecutive TCLK cycles. This is necessary in order to ensure
that the JTAG controller does not enter any of the test modes
after device power-up. In this JTAG reset state, the rest of the
device will be in normal operation.
Note. The order of device reset (using RESET) and JTAG
initialization does not matter.
3-Level Select Inputs
Each 3-Level select inputs reports as two bits in the scan
register. These bits report the LOW, MID, and HIGH state of
the associated input as 00, 10, and 11 respectively

7. Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
8. 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.
9. The common mode range defines the allowable range of REFCLKx+ and REFCLKx− when REFCLKx+ = REFCLKx−. This marks the zero-crossing between
the true and complement inputs as the signal switches between a logic-1 and a logic-0.

10. Maximum ICC is measured with VCC = MAX, TA = 25°C, with both channels and Serial Line Drivers enabled, sending a continuous alternating 01 pattern, and
outputs unloaded.
11. Typical ICC is measured under similar conditions except with VCC = 3.3V, TA = 25°C, with both channels enabled and one Serial Line Driver per channel sending
a continuous alternating 01 pattern. The redundant outputs on each channel are powered down.
12. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
13. The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.
14. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.
15. The ratio of rise time to falling time must not vary by greater than 2:1.
16. 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.
17. All transmit AC timing parameters measured with 1 ns typical rise time and fall time.
