Is it possible to run the ADV7181C off of a 1.8v clk source connected
to the XTAL input (by setting the XTAL_TTL_SEL bit to '0') ???
The datasheet for the ADV7181C specs a 3.3v clk, but the XTAL_TTL_SEL
bit looks like it might be a way to configure it for 1.8v operation. The
ADV7180 accepts a 1.8v clock and operates fine. I have a board that is
already using the ADV7180s and I am adding the ADV7181Cs to the design.
I would like to use the same oscillator source for all of the devices.
