Table 17. TCK78[A:B] Source Selection
Recommended Transmit Clock Distribution for the ORT82G5
As an example of the recommended clock distribution approach, TSYS_CLK_A[A:D] can be sourced by TCK78A
as shown in Figure 25 if the transmit line rate are common for all four channels in a quad. Similar clocking would be
used for Quad B.
Figure 25. 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 26 can be used. The gure shows TSYS_CLK_AA and TSYS_CLK_AB being sourced by TCK78A and
TSYS_CLK_AC and TSYS_CLK_AD being sourced by TCK78A/2 (the division is done in FPGA logic). Similar
clocking would be used for Quad B.
