Does anyone have experience with a circuit with good rise-time and low
jitter?
Sometimes the simplest solutions can be best. In this case, capacitive

What is the goal of the isolation? Breaking ground loops? Or safety?
How much isolation voltage do you need?

HCPL7101 and similar 50MBaud optocouplers claim 50ps rms jitter.
Some non optical isolated couplers specify ~30ps jitter.

Hi all,
I'm looking for a solution for galvanic isolation of a 1PPS signal-input to
a distribution amplifier.
We have an old box using HCPL-2411 at the input followed by 74LS04, but the
degraded rise-time (from below 3ns out of a clock, to >12 ns out of the
box) and increased jitter (from below TI
