Hi all,
I just discovered that TI makes a TDC chip called THS788, see
http://www.ti.com/product/ths788 for more info. Interesting specs, but rather
expensive. Has anyone from the list had a chance to experiment with this device?
Cheers

Bah, yes, my bad: picoseconds is the relevant timescale here.

Ok, for a legit 12 ps with 0.1 ps drift and 200 mega samples per second -
not to many alternatives. The FPGA stuff will get you to 50 to 100 ps on the

Hi,
The NIM Negative pulse is indeed problematic when trying to interface to
FPGA logic!
The solution I have used in the past is a board based around a Maxim
MAX9601[1] acting as a comparator on the incoming NIIM pulse, and
configuring the output for connection to the FPGA. Judging by the
Two suggestions:
How about using an off-the-shelf Wavecrest counter?
These have a 0.8ps resolution, and typically have a noise floor of around
3ps when averaging. They certainly can do 10ps single shot. There is a
