[time-nuts] TAC/TDC

[Josef Kölbl]

I am looking for a commercial drop-in module/solution of a 
time-to-analog or even time-to-digital converter module with <= 1 ps 
resolution (device should eventually go on a printed-circuit board). 
Critical issues are: linearity, stability, accuracy, jitter and 
precision. The maximum time interval to be measured shall be <= 25 ns. 
Do you know of any commercial products? I will require more than 1 unit.
Thanks.
Josef
