The ADV7393 has a DAC output designed for 37.5 or 300 Ohm loads. Any ESD protection as long as it meets the voltage limits should work. You just have to make sure the protection does not effect the higher frequency components of the signal.
In my opinion the 37.5 Ohm load circuit is harder to protect since there is no series resistance in the signal path for the ESD protection to work against. I would design the part for 300 Ohm load, buffers and 75 Ohm series resistors. Then put the true ESD protection on the output side of the series resistors. There are any number of bridge ESD protection devices you can use as long as they do not effect the frequency components of the signal.
