We are currently trying to pass HDMI 1.4b compliance on our board using the ADV7619.
The test lab reports that we are failing on two items:
- 8-5 TMDS min differential swing tolerance: the reported minimum voltage is 170mV, while it should be <= 150mV to pass
- 8-7 TMDS jitter tolerance: it is failing on 27MHz and 74.25MHz clock formats (148.5MHz is OK).
Has the compliance with HDMI 1.4b been verified with the ADV7619, and are you aware of such issues?
Any suggestion to pass, for instance different settings to program in the chip?
