TRIROC 1A IS DEPRECATED – NOT RECOMMENDED FOR NEW DESIGN Please consider Temporoc for new design
Triroc 1A is a 64-channel front-end ASIC designed to readout silicon photomultipliers (SiPM) with both polarities for particle time-of-flight measurement applications. Triroc 1A 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 30ps-bin TDC.
The concept of the ASIC is to combine 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.
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 10 mW/channel, excluding buffers used to output the signals. The main application of Triroc 1A is PET time-of-flight but it can also be used for any application that requires both accurate time resolution and precise energy measurement. Triroc is available in BGA packaging (12x12mm, 353 balls).
