I am trying to drive my LTC6957-2 with a 2v sinewave originated from an OCXO.
for some reason I get sinewave and not square wave at the output pins. the levels are LVDS levels but the shape is a sinewave.
I tried to load it with 100Ohm resistor as well as with ADCLK944 evalboard set LVDS input.
I am using the eval board for LTC6957.
what can be the issue? is it expecting a square wave input?
