UHD-SDI GT v2.0 - Switching between PICXO and FRACXO has no impact on the ports of the core in Vivado 2019.2?


When using the UHD-SDI GT core in Vivado 2019.2 with "Enable PICXO ports" enabled, switching between FRACXO and PICXO has no impact on the ports of the IP.

On GTY, the ports enabled are always the ports used for FRACXO:

  • intf_0_gt_common_sdm0data_in
  • intf_0_gt_common_sdm0reset_in
  • intf_0_gt_common_sdm0toggle_in
  • intf_0_gt_common_sdm0width_in

On GTX, the port enabled is always the port used for PICXO:

  • intf_0_txpippmstepsize


This is a known issue in Vivado 2019.2, where switching the option between PIXCO and FRACXO has no impact.

This issue is planned to be fixed in a future release.
