Hi Xilinx

 

   HDMI TX pll type is CPLL,in UG476 the CPLL operate range between 1.6GHz to 3.3Ghz.

  TX Max GT Line Rate is 5.94Ghz in vid_phy IP. In my opinion,MAX CPLL freqency and Max GT line rate are conflicting.

The MAX GT Line rate in Video PHY GUI is based on the max line rate needed for NI-DRU, QPLL and CPLL, as it can be configured via driver to use QPLL or CPLL.

 

Please take a look at table 3-8 (page 70) of PG230 , the CPLL Line rate range aligns with UG476GT_Line_rate.JPG
