Figure 26. Mixed Rate Transmit Clocking for a Single Block (Similar Connections Would Be Used for Block B)
Receive Clock Source Selection and Recommended Clock Distribution
In the receive path, one clock per bank of four channels, called RCK78[A:B], is sent to the FPGA logic. The control
register bits RCKSEL[0:1][A:B] are used to select the clock source for these clocks. The selection of the source for
RCK78[A:B] is controlled by these bits as shown in Table 18.
Table 18. RCK78[A:B] Source Selection
In the receive channel alignment bypass mode the data and recovered clocks for the eight channels (four per SER-
DES quad) are independent. The data for each channel are synchronized to the recovered clock from that channel.
