Hi there, I am trying to use the ATX Plls on the HDMI reference design. I have re-compiled the software to use the ATX configuration, however the TX PLLs are not getting locked.Any suggestions/information on this front?

In case this may be useful to someone. I can post more details on request:

[*]It is not advisable to use ATX Plls for lower HDMI rates, this due to jitter performance restrictions of the ATX.
[*]The NIOS sw that comes with the reference design has got two cases, for fPLL and ATX-PLLs, however the case for the ATX has a bug: The re-calibration process does not distinguish fPLL/ATX cases, however the re-calibration process for each is slightly different.Hope it helps
