ADV7626 - Port Status Information

Guys,

I am looking for more information on HDMI inputs and outputs of the ADV7625/26/27 products.

I can easily tell when someone connects a cable on the RX side because of the +5VDC detection. However, I would like to check TMDS activity as well. However, I can only get good TMDS CLK sensing when this particular RX port is routed to a RxA or RxB path. I would like to get this information from the source even if the signal is not yet routed to an output.

Secondly, I'd like to check TMDS CLK activity on each output port. I am thinking using the measurement section is the mostly solution. I'd like to get your opinions.

Thank you for your quick response.

Phil
