AVM16 - 16 channel VME 12 bit x 160 MHz ADC

AVM16 (VME version) and AVX16 (VXS version) are 16 channel 12 bit flash ADC’s equipped with 5 FPGAs for data preprocessing.

The feature extraction FPGA modules allow to compute pulse integrals (also for overlapping pulses), measure and subtract pedestals, extrapolate pulse arrival times with 1.5 ns resolution, extract maxima and minima of the signal and disentangle pile up events in real time

Main features

  • 16 channel 12bit/160MHz digitizer in VME,
  • LEMO or flat cable input, +/- 1V default input voltage, baseline shift
  • 10Hz - 100 MHz band width for DC coupled version, 200kHz – user limited band width for AC coupled version
  • Event buffering, 4 buffers of 1024 samples (6.4us) for 16 channels
  • VME Addressing modes: A24/D16, A24/D32, A32/D16, A32/D32, AD64, BLT, MBLT
  • Internal  or external clock
