The ADV7622/3 and ADV7511 have different ARC termination circuits. On the ADV7511, the coupling capacitors are in-line but on the ADV7622, the coupling capacitors are in parallel. Why is this?
ADV7511 has a 3-pin architecture : 2 dedicated HEAC pins and 1 dedicated HPD pin.
However on the HDMI connector, its the same pin thats used for HEAC- and HPD as well! (Pin19 of TYPE-A connector).
In that case, how will be the connections? Will the HEAC- on HDMI connector be connected to HEAC- and HPD as well? Please advice.
