Table 10-7. Transmit Framer Pin Signal Timing Source Select
10.2.3.3 Receive Line Interface Pin Timing Source Selection
(RPOSn/RDATn, RNEGn/RLCVn/ROHMIn)
The receive line interface signal pin group must clocked in with the RLCLK clock input pin. When the LIU is
enabled, the receive line interface pins are not used so there is no valid clock reference.
Table 10-8. Receive Line Interface Pin Signal Timing Source Select
10.2.3.4 Receiver Framer and Fractional Pin Timing Source Selection
(RSERn, RSOFOn/RDENn/RFOHENOn, RFOHENIn/RPDENIn, RPDATn)
The receive framer and fractional signal pin group has the same functional timing clock source as the RCLKOn pin
described in
Other clock pins can be used for the external timing. The RCLKOn receive clock output pin is always a valid output
clock for external logic to use for these signals when PORT.CR3.RFTS=0.
The receive framer and fractional timing select bit (RFTS) is used to select input or output clock pin timing. When
RFTS=0, output clock timing is selected. When RFTS=1, input clock timing is selected. If RFTS is set for input
clock timing and an output clock pin is used, or If RFTS is set for output clock timing and an input clock pin is used,
then the setup, hold and delay timings, as specified in
of RFTS=1 and other modes in which there is no input clock pin available for external timing since the clock source
is derived internally from the RX LIU or the CLAD.
