DisplayPort 1.4 RX Subsystem - What clock needs to be used as the GT reference clock?

描述

What clock do I need to use as the GT reference clock for the DisplayPort 1.4 RX Subsystem?

Should I use the clock from the retimer?

解决方案

Only one 270MHz clock from an on-board clock needs to be used for both TX and RX. There is no need to use the clock from the retimer.

For a working example, refer to the Application Example Design (generated from Vivado as per Chapter 5 of (PG233)).
