The use of a synchroniser loses no information apart from fine details about
the metastability response of the sampling flipflop. With a 10Hz offset and a
10MHz clock the sampling resolution is 100fs with the phase difference between
the flipflop clock and data input transitions changing
Hi Simon, I am the initiator and leader of the White Rabbit project,
which in the context of these discussions is more a disqualifier than
anything, since I do very little technical work these days,
unfortunately. Please forgive me if I have misunderstood what you are
trying to do. Some tentative

Hi,

Javier,
I'm merely implementing a poor man's copy of the ideas in the White
Rabbit project, so thank you for taking the time to post.

Hi Simon,
I need to find some spare time, something which is not in rich volumen
right now.

Hi Magnus,
What was the outcome ? Did it work, and what were the constraints or
problems encountered ?

Hi
Most ECL families have more trouble with 1/F noise than fast silicon saturated
logic. That makes them poor candidates for this sort of thing.

Dave, I think I have a MiniCircuits ZAPD-3(?) splitter or two kicking
around. I'll try to get a look in the stash this weekend.

Pete, I see a ZAPD-30 on the miniCircuits web site. Might those be the
models that you have?
If so, (and assuming that you can find them), how much for a couple?
Thanks,

Is it silicon or is it something more exotic? In general, exotic is not good
for 1/F noise.

Data sheets say submicron CMOS.
