Poproc
Description
POPROC is a MA-PMT readout out chip, specifically design for fast counting output. This chip is fully analog and features differential trigger output for each detector channel. The ASIC is designed to accept negative polarity input and can readout up to 64 channels.
POPROC allows triggering down to 1/3 p.e. and provides low-voltage differential trigger output for each channel with an excellent timing resolution (better than 20ps FWHM) and excellent double-peak separation (100% efficiency on 3 ns separated single photo-electrons). POPROC allows fast single photon counting over 300MHz per channel.
Channel-by-channel calibration on the trigger threshold is also possible thanks to 6-bit DACs.
POPROC features a GHz measurement line composed of a current conveyor followed by a fast discriminator and low swing differential output driver.

Poproc is a GenerIC family IC
GenerIC is a new read-out chip family by Weeroc. GenerIC features fast flip-chip packaged integrated circuits pin-to-pin compatible one with another. Changing detector and its front-end electronic become straightforward with GenerIC family. Pin to pin compatibility allow keeping the same front-end electronics and change detector and front-end ASIC while keeping downstream data stream identical. GenerIC makes easy multi-detector read-out by having a common read-out scheme independant of the detector. Check the GenerIC family :
