  • Optimized for SiPM

  • Number of channels: 64

  • Outputs: Digital output (dual ADC and dual TDC per channel) – selectable transmission mode. 1 multiplexed time trigger output, 2 ASIC trigger 0R outputs (64 channels, 2 levels)

  • Input Polarity: Positive

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.
