easiroc description
EASIROC Description
  • Number of channels: 32
  • Analogue core :
    • Internal input 8-bit DAC (0-4.5V) for individual SiPM gain adjustment
    • Individually addressable calibration injection capacitance
    • Energy measurement : 14-bit dynamic range
      • 2 tuneable gains followed by 2 adjustable shapers
      • Analogue memory (Track & Hold cell) for low gain and high gain
      • Common 10-bit DAC for threshold adjustment
      • Variable shaping time: from 25 ns to 175 ns
      • from 160 fC 320 pC (ie. 1 pe 2000 pe @ SiPM gain = 106)
      • pe/noise ratio : ~10 @ SiPM gain 106
    • Trigger output
      • pe/noise ratio on trigger channel : ~ 25
      • Fast shaper : ~15ns
      • Trigger on 50 fC (ie. 1/3 pe @ SiPM gain = 106)
easiroc evaluation board
EASIROC Evaluation Board
  • Enables tests of most of the functionality of the EASIROC.
  • Full access to slow control 456 bits.
  • Pins on I/O allow for easy monitoring.
  • External ADCs for analogue signal tests.
