ID900 Time Controller

Timing, delay and pattern generation all with 20 picoseconds precision

  • Timestamping and histogramming
  • Delay generation with multi-hit ability
  • Pattern generation
  • 1 GHz counters

IDQ’s Time Controller is an all-in-one device designed for flexibility and it efficiently solves a large number of problems encountered in the laboratory. Its core consists of 4 high-speed (<20 ps precision, 100 Mcps rate) inputs and 4 high-speed outputs, interconnected by reconfigurable logic. The Time Controller performs the functions of a number of devices: time-to-digital converter, coincidence counter, delay generator, pattern generator, counter and discriminator. This is complemented by a 10 Gbps link to the host computer for fast data transfers, by auxiliary analogue and digital I/O for interfacing with external devices.

An advanced synchronization circuit allows for up to 16 devices to be “daisy-chained” for a total of 64 fast input and output channels.
