Overview
The CAEN Mod. VX1190B-2eSST is a 64 channel Multihit TDC, housed in a 1-unit wide VME64X 6U module. The unit features High Performance Time to Digital Converter chips developed by CERN. LSB can be set at 100 ps (19 bit resolution, 52 µs FSR), 200 ps (19 bit, 104 µs FSR) or 800 ps (17 bit, 104 µs FSR).
The channels can be enabled for the detection of hits rising/falling edges or for their width measurement (both the edges’ timing, and the hit width can be measured with the selected resolution). For each channel there is a digital adjustment for the zero-ing of any offsets. The data acquisition can be programmed in “Events” (“Trigger Matching Mode”, with a programmable time window) or in “Continuous Storage Mode”. Both ECL and LVDS input signals are supported.

Consult our connectors reference page for technical information.
The module programming is performed via a microcontroller that implements a high-level user friendly interface. The VME interface allows the module to work in A24 and A32 addressing modes. The board houses a 32 k x 32 bit deep Output Buffer that can be readout via VME in a completely independent way from the acquisition itself.
The device supports MBLT, CBLT and 2eSST readout modes. Live insertion is also supported.
