I have a dumb question. This relates to the LVDS interface for Sonet
framers.
I was of the opinion that the LVDS interaface would always sample the data
at the crossing
of the differential clock (I mean crossing of the p and n of the diff
clcok).
If this is true, then it would make the interface independent of the duty
cycle of the clock.
(since as the duty cycle of p increases the duty cycle of n decreases
keeping the distance between
the two crossing points the same). But, it appears that that is not the way
the receiver works.
(atleast from the documentation). Can someone explain how does it really
work????
