LogiCORE UHD-SDI - Why do the comments in the x7gtx_uhdsid_control.v file in XAPP1249 v1.1 say that the DRP does not need to be connected for a TX-Only solution?

Description

Why do the comments in the x7gtx_uhdsid_control.v file in XAPP1249 v1.1 say that the DRP does not need to be connected for a TX-Only solution?

Solution

This is incorrect and will be removed in a future update.

The DPR interface is always required in order to properly select the divide values for the various rates.

You will need the PicoBlaze controller if you are implementing any of the following configurations:

  • UHD-SDI Rx and Tx
  • UHD-SDI Rx Only
  • UHD-SDI TX Only
