I've noted before that LVDS line receivers make pretty good, fast, cheap rrio comparators. This looks even better:
It has 425 ps typ prop delay, pretty low input offset, and a little hysteresis.
The CML outputs seem to be pure current sinks that can drive up to at least 50 ohms.

Interesting part, thanks.
The 70 ps jitter spec seems a bit out of line with the eye diagrams.
Cheers

We noticed that. That's the max p-p "deterministic" jitter spec with a
1.5 GBPS PRBS pattern input, which represents a frequency response limitation rather than real noise. With a square-wave input, the spec is 1 ps RMS typ, and I'd expect it to be less in real life.-- John Larkin Highland Technology, Inc lunatic fringe electronics
