Temporoc
Multi-Purpose Mixed-Signal SiPM read-out ASIC
Description
Temporoc is a 64-channel front-end ASIC designed to readout silicon photomultipliers (SiPMs) for particle time-of-flight measurement applications. Temporoc combines a very fast and low-jitter trigger with accurate charge and time measurements. Energy and time are digitized internally with a 10-bit ADC and 50ps-bin TDC. In total, Temporoc is capable of providing two distinct time tagging and two energy measurement of each event.
The concept of this ASIC is combining two measurement lines that won’t interfere one with each other to measure both first incident photon timing measurement and whole crystal light charge integration. Additionally, Temporoc features clustering triggers readout which could be useful for particle detection with monolithic scintillator.
An adjustment of the SiPM high voltage is possible using a channel-by-channel input DAC. It allows a fine SiPM gain and dark noise adjustment at the system level to correct for the non-uniformity of SiPMs.
The power consumption is 5 mW/channel. Temporoc is suitable for any application that requires both accurate time resolution and precise energy measurement such as time-of-flight gamma detection.

Temporoc 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. Temporoc is the only GenerIC read-out-chip with a fully digital output, nvertheless, compatibility of digital pin and input are preserved with other analogue generIC chips. Check the GenerIC family :
