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 coprocessors and corresponding CYV15G0203TB Serializer and CYV15G0204RB Reclocking Deserializer chips. The CYV15G0203TB satisfies the SMPTE-259M and SMPTE292M 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. 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 multiformat routers, switchers, format converters, and cameras.

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. TXERRA TXERRB LVTTL Output, synchronous to REFCLKx↑ [3], asynchronous to transmit channel enable / disable, asynchronous to loss 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 single-ended LVTTL input clock Reference Clock. REFCLKx± clock inputs are used as the timing references for the associated transmit PLL. These input clocks 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 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. See Table 2 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±.

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 highspeed serial links from multiple sources to multiple destinations. This device supports two 10-bit channels. 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. CYV15G0203TB Transmit Data Path 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). 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. ** Transmit BIST 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 Page 8 of 19 PRELIMINARY associated channel. The serial signaling-rate and allowable range of REFCLKx± frequencies are listed in Table 1. Table 1. Operating Speed Settings SPDSELx TXRATEx REFCLKx± Frequency (MHz) LOW 1 reserved 0 19.5 – 40 MID (Open) 1 20 – 40 0 40 – 80 HIGH 1 40 – 75 0 80 – 150 Signaling Rate (Mbps) 195 – 400 400 – 800 800 – 1500 The REFCLKx± inputs are differential inputs with each input internally biased to 1.4V. If the REFCLKx+ 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 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. CYV15G0203TB 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. 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 lists the configuration latches within the device including the initialization value of the latches upon the assertion of RESET. Table 3 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. Document #: 38-02105 Rev. ** Page 9 of 19 CYV15G0203TB PRELIMINARY Table 2. Device Configuration and Control Latch Descriptions (continued) 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 2. Set the static latch banks for the target channel. The following is a series of ordered events needed to load the configuration latches on a per channel basis: 3. Set the dynamic bank of latches for the target channel. Enable the output drivers. [Required step.] 1. Pulse RESET Low after device power-up. This operation resets both channels. 4. Reset the Phase Alignment Buffer for the target channel.

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. 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.

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 1ns typical rise time and fall time.
