General Standards Inc. makes a PMC module
with 64 parallel 16-bit digitizers. It can be
configured to 64 single-ended, 32 differential
(digital differences!) channels. Very compact
and not extremely expensive (3.5k); EPICS
drivers available.

EPICS colleagues:

The LLNL group that is supplying the diagnostics to commission the LCLS needs a digitizer for an energy measurement instrument (calorimeter) with the following characteristics:

 - 100 channels sampled simultaneously
 - each channel takes 100 samples at 10us per sample (1 ms total time)
 - differential inputs
 - 12 bits minimum; 14 or even 16 bits preferred
 - sampling repeats at 120 Hz major cycle with trigger

A VME or VXI format is ideal.

Any suggestions are most welcome. Ideally, we can discuss this in depth at the June meeting.
