Figure 2–36. Sixteen Non-Bonded Receiver Channels without Rate Match for Example 7
Because the recovered clock rx_clkout signals from all 16 channels have a 0 PPM
frequency difference, you can use a single rx_clkout to clock the receiver phase
compensation FIFO in all 16 channels. This results in only one global, regional, or
global and regional clock resource being used instead of 16. To achieve this, you must
select the receiver phase compensation FIFO read clocks instead of the Quartus II
software default selection, as described in
Compensation FIFO Read Clock” on page
