ADV7611/ADV7619 Equalizer Settings

Hi All,

 

We are very shortly going to production with a product that uses both the ADV7611 and ADV7619 HDMI receivers.

We've done significant testing with both devices and are generally happy with the performance of the devices.

However very recently we have completed some "scenario" testing and found that sources with strong drive and/or fast edges over short cable lengths do not perform well, we are getting a significant amount of bit errors within the serial stream and believe it is due to the equalizers.

 

The post below would indicate that the automated equalizers can be manually overridden with some "hidden" registers.

My question is, offline would I be able to obtain a list of the manual EQ registers and their definitions?

 

The company I work for already has an "NDA" with Analog Devices.

 

Thanks.
