Hello,
I wanted to see if we have any insight on the device performance when the differential input amplitude is between 100mV and 500mV. This is below the minimum spec for V(ID), but the datasheet mentions the device will still function but with degraded AC specs. We want to use a standard LVDS driver that has a 250mV minimum output amplitude.
The AC specs I'm most interested in are the out-to-out skew and jitter. Right now the specs for those parameters are pretty tight and we can afford them to degrade a decent amount.
I realize this is a gray area, but what I wanted to ask:
- When the AC specs degrade, will all of them degrade or are there a few in particular that are most severely affected?
- Do we have a sense of how much those specs will stray when operating below 500mV V(ID)? We'd like to keep out-to-out skew to 500ps (10x the datasheet max) and jitter to 400ps (500x the datasheet max).
Thank you!
Regards,
Ryan B.
