DMTD or dual mixer time difference.
An all digital version (DDMTD like that used in CERN's White Rabbit)
is also possible
3 (and M) input versions are also feasible.
Either an FPGA or a CPD plus a microprocessor are required to ensure
low cost.
I've lying around one of these little things:

(that really I purchased only for amusement along with a bigger and
quite more expensive FPGA board). It lacks I/Fs except GPIOs (it only
has an USB that really are more intended for JTAG functionalities than
for other things), but seems a nice unexpensive core for a DDMTD. It
could be a fun project :) Anyone would like to join? ;)
