[Halld-pid] CAEN VX1290 and DAQ compatibility

[Alexander Somov]

Hi,

I am currently using CAEN VX1290 for the SiPM timing measurements.
It's a very good TDC ! The intrinsic resolution is around
30 ps (in the spec they mention 25 ps)

The clock and trigger distributions are done through the front panel.
We read it out using CODA (I think that there should be no problems
with the block readout).

Hall B guys have a big experience using this board (and are 'happy' 
with it) and are planning to use them in the future. As far as I
know they are mostly using VX1190 which has worse resolution, but
in general,  is very similar to 1290.


Cheers,
       Alex

P.S. We should certainly go through some 'compatibility' details but
could consider using this board for the TOF and SC. The board is
more expensive, $8-9k (?) per board (32 ch) as far as I remember -
but we don't have many channels in these detectors.
