Figure 18. Transmit Clocking for a Single Block (Similar Connections Would Be Used for Block B)
If the transmit line rate is mixed between half and full rate among the channels, then the scheme shown in
Figure 19 can be used. The gure shows TSYS_CLK_AC being sourced by TCK78A and TSYS_CLK_AD being
sourced by TCK78A/2 (the division is done in FPGA logic). Similar clocking would be used for Block B.

Receive Clock Source Selection and Recommended Clock Distribution
In the receive path, one clock per block of two channels, called RCK78[A:B], is sent to the FPGA logic. The control
register bits RCKSEL[A:B] is used to select the clock source for these clocks. The selection of the source for
RCK78[A:B] is controlled by this bit as shown in Table 15.
Table 15. RCK78[A:B] Source Selection
In the receive channel alignment bypass mode the data and recovered clocks for the four channels are indepen-
dent. The data for each channel are synchronized to the recovered clock from that channel.
Figure 21 shows the recommended receive clocking for a single block.
