We are evaluating ADV7611.
We are not using the XTALN(#59).
Please let me know how to take care of this unused pins.
floating or connect to GND or ...?.
XTALN is an output so it can be left open.
Thank you for quick reply.
However,we thought that XTALN is input pin. below,
Refer to the Table4 of UG-180 Hardware User Guide.
Is XTALN is output pin?.
I saw that however, normally this pin set is part of a crystal oscillator circuit and those circuits have one input and one output that drives the crystal. The XTALP is the input and can be driven like you want to do. If you look at the functional block diagram you will see that XTALN is an output. XTALN in crystal mode is a driver that drives the crystal. I think the description is a bit misleading, it uses the common conception of a crystal oscillator circuit but and a true oscillator circuit has one input pin and one output pin.
However if you want to play it safe you can tie a 100k resistor to ground
Thank you for making the time for my question.
