“Dedicated reference clock pin” and “RX reference clock pin”

Hi Yang Ni

Thanks for your inquiry. Sorry for late response as I was getting clarification on your request.

Both the pins are in transceiver bank as described below:

1. Dedicated reference clock – this is the dedicated refclk pin for XCVR. In the pin connection guideline, its name is REFLKC_GXB
2. RX reference clock pin – this is transceiver RX channel where it can be used as refclk pin as well. You can find the pin with names i.e GXB_RX, GXB_REFCLK_CH in the pin connection guideline.
