VFAT2 RD51 Adapter

SRS adaptation

  • f

an existing VFAT2 hybrid from TOTEM/CMS

  • HDMI (D)
  • LDOs
  • Separate A/D power

planes

  • Multiple options for

the power connections 5

VMM1/VMM2

  • Designed for ATLAS NSW
  • Data driven (self-trigger)
  • Variable gain/shaping
  • dual polarity,
  • adj. gain (0.5-9 mV/fC),
  • adj. peaktime (25-200 ns),
  • DDF shaper
  • Peak and time readout
  • Trigger-out interface
  • Integrated ADC/TDC (10b/1ns)

Integration of VMM2 into SRS

VMM2 VMM2

FPGA (S6) HDMI

  • 2 x VMM2 = 128 ch.
  • Small FPGA(eg. Spartan6)/ASIC* (I/F and control)
  • Readout via Digital C-Card

* An ASIC is planned in the ATLAS NSW framework
