I want to implement to HDMI Audio Return Channel on the HDMI Receiver Board, HDMI Receiver Device is ADV7612.
Can any one suggest how to implement it?.
OK, i got some clarity.
For HDMi ARC, the HDMI Receiver side, we need the SPDIF Transmitter.
The SPDIF Transmitter input is Stereo Analog Audio, the output in Differential Biphase (SPDIF) mode (not TTL mode, it has to be Coaxial Interface Mode), had give to HDMI HEAC+ and HEAC- pins of the HDMI Conenctor (HDMI 1.4 Signal Pinout has to use).
The Interface is AC Coupled.
The ADV7612 doesn't actually have ARC support built into it, you'd have to do it outside along the lines you mention.
Thanks, my understand is correct?. Like Just Feed the SPDIF Transmitter Output to HDMI ARC (HEAC+ and HEAC-) signals. Not Required any extra logic.
Please clarify, or send document or refernce design for clear understand.
You really would need to check the HDMI 1.4 specification and the IEC specs that it references for ARC. You'd need to get them from HDMI.org, we can't supply them. I don't think it's quite that easy.
I had seen the ADV7511 HDMI Transmitter Deatils, and also Evaluation Board.
The ADV7511 had the HDMI ARC Receiver feature, is there any deatils about how ADV7511 Evaluation Board tested with HDMI ARC feature?.
I am sure ADV7511 HDMi ARC tested somehow, can send me the ADV7511 HDMI ARC Receiver test procedure to underatnd more about HDMI ARC.
We use the HDMI compliance test specification for our 7511 testing, you can download it from HDMI.org assuming you are an adopter. We did make a board we use to do the test. I'm checking if we can get you the schematics for the board. That's realistically all we can provide that you couldn't get from HDMI directly.
Thanks, Can you find and send the your test board deatils ASAP. I had gone through the HDMI Specifications and HDMI CTS details, But it's not clear how to design ARC.
Your documnets may help us.
I'll post them as soon as I get them. That should be just what you need since it's meant to simulate exactly what you want to do. The test board takes optical in with ARC out.
Attached is the schematic of the board I mentioned. On the second page is the circuit that takes SPDIF and puts in on the ARC lines.
