Figure 29. Receive Clocking for a Dual Alignment in a Single Quad (Similar Connections Would Be Used for
Quad B)
For receive quad alignment, RSYS_CLK_[A1,B1] and RSYS_CLK_[A2,B2] can be tied together as shown for quad
A and B in Figure 30. In receive eight-channel alignment, either RCK78A or RCK78B can be used to source
RSYS_CLK_[A1,A2] and RSYS_CLK_[B1,B2] as shown in Figure 31.
