ADV7626 : Test pin

Hello,

I will develop the products of two equipped with HDMI.

I will use the ADV7625 and ADV7626 for these products respectively.


I want to develop these two products as a common board design.

I have some questions in relation to this.

Is it possible to use the part of ADV7626  TEST pins with non connection?

The ADV7625 is allocated to the signals enhanced to the NC pins of ADV7626.

I will use only the part of the signal to which these are enhanced.

And, I will not use other enhanced signal pins.

Can I use the AD7625 with non connection for it?

Best Regards,

Mr.K

    I would connect the pins as shown in the connection column.  4.7k pull downs to ADV7625 input pins will not hurt anything.

    If you are not going to us an input on the ADV7625 and the pin is a clock or control signal I would pull it to ground with a 4.7k resistor.
