Table 10-9. Receive Framer Pin Signal Timing Source Select
10.2.4 Clock Structures On Signal IO Pins
The signals on the input pins (TSOFIn, TSERn) can be used with any of the clock pins for setup/hold timing on
clock input and output pins. There will be a flop at each input whose clock is connected to the signal from the input
or output clock source pins with as little delay as possible from the signal on the clock IO pins. This means using
the input clock signal before the delays of the internal clock tree to clock the input signals, and using the output
clock signals used to drive the output clock pins to clock the input signals.
The signals on the output pins (TPOSn/TDATn, TNEGn, TSOFOn/TDENn, RSERn, RSOFOn/RDENn) can be with
any of the clock sources for delay timing. There will be a flop at each output whose clock is connected to the signal
from the input or output clock source pins with as little delay as possible from the signal on the clock IO pins. This
means using the input clock signal before the delays of the internal clock tree to clock the input signals, and using
the output clock signals used to drive the output clock pins to clock the input signals.
