We have been asked to develop a TDC card in FMC (VITA 57) form factor. In
principle we plan to use ACAM's TDC-GPX, but our specs are much more

Magnus,
with regard to your questions:
measurement rate = 1 kHz
rms jitter = 10 ps
linearity better 3 ps
resolution of 1 ps is the minimum differential measurement which can be
made (ie granularity).
Thanks, this makes your requirements much clearer.

Hmm. How do you intend to discriminate short pulses? It needs to be done in
a way that it does not significantly impairs on the timing measurement.

Just finished editing 25 papers on process control for FDA (Food
and Drug Administration) regulated industries, so here are a few
reflexive neuron firings.
The FDA requires that the user requirements be captured first, in
a way that can be understood by both the user and the vendor of

Do you also require precision in the ~ 1 ps range as well as resolution?
If so, that opens up a whole series of issues about:
1) How long since it was calibrated
2) Temperature and other environmental effects
3) Traceability of calibration
Not a

If such a device is not available at a practical price / not available at all -
Are you open to building a TDC / TAC from parts?
