PIN and NIN should be differentially driven and ac-coupled for optimum sensitivity.

When ac-coupled, the LOS assert and deassert time is dominated by the RC time constant of the ac coupling capacitor and the 50 Ω input termination of the
ADN2812 input stage.

Jitter tolerance of the ADN2812 at these jitter frequencies is better than what the test equipment is able to measure.
