We are currently trying to pass HDMI 1.4b compliance on our board using the ADV7441a.
The test lab reports that we are failing on the following item:
- 8-5 TMDS mininum differential swing tolerance:
the reported minimum voltage is 150mV, while it should be <150mV (at least 140,mV )to pass.
Any suggestion to pass, for instance different settings to program in the chip or how to change the hardware to increase the sensitivity of the chip?
