Team,

 

As a follow on to this discussion: http://ez.analog.com/message/60064

 

The customer was able to use the guidance your team provided to design the ADV7612 into their product.

 

Unfortunately, the  protoypes came back this week, and while they can talk to both of the ADV7612s over the I2C bus with no problem - and identify both Video and Audio formats on the inputs - their outputs appear to be dead.

 

What type of guidance can we provide with regards to troubleshooting the outputs on the ADV7612?

 

Of course this can wait till everyone returns from the holiday Monday.

 

Thanks in advance for your help.

 

Mike
