The example design that can be generated for the JESD204C core in Vivado (see Example Design) delivers a JESD204 PHY core with the settings used from the JESD204C GUI. When configuring a JESD204 PHY core for use with a JESD204C core, the subsequent values must be set as shows in the following image:
- The transceiver type must be set to GTHE3, GTHE4, GTYE3, or GTYE4.
- The JESD204 Version is hard-coded to JESD204C as the JESD204 IP is discontinued.
- The line coding must be set to
64B66Bor8B10B. - The line rate must be set to the same value as defined in the JESD204C GUI.

It is possible to share a JESD204 PHY between different instances of JESD204C cores. The TX and RX are configured separately and can therefore run at different line rates and line coding standards.
