Hi ADI ,
We met another problem , I need your advice.
We have Rx sense problem with our sink ( using ADV3003 --> ADV7604) and customer source ( AD9889B).
-- I guess so that , but it might not be Rx sense. But I can not make sure now.
In a following condition , Source did not output TMDS Tx , he keep AD9889 power down mode.
1: Power on our sink before Source power on.
2: Source Power ON.
3:Source DDC start to read our EDID (--> Trigger with HPD H )
4:Source read EDID but not once , he read 3 or 4 times re-read.
5:After that , sometimes TMDS Tx will be coming our sink , but sometimes not.
--> It looks like "Keep power down mode of AD9889B".
Then , my question is ;
How to wake up source AD9889B from power down mode by sink ?
* HPD toggle L/H again ?
* ADV3003 TMDS termination ( Tx EN of ADV3003 toggle 0--1) ?
* Or do you have another method of wake up source AD9889B from sink ?
We have not any detail information of source equipment.
