We use another part, a slower LVDS-to-CMOS receiver (SN65LVDS2DBVR) in another app. At roughly 1 volt per ns input, jitter is probably below

1 ps RMS. The LVDS parts are pretty good.

What I really like is that they get you from small signals up to 3.3 or 5-volt swings with edges in the hundreds of ps. That's usually hard to do.

Cool, thanks.

Watching a train wreck with interest doesn't intimate wanting to be in one.
