NAMC-psTimer

NAMC-psTimer

AMC Fast Timing System with ps resolution

The NAMC-psTimer is designed timing systems for large installations such as the European XFEL (X-Ray Free Electron Laser) in Hamburg, Germany, but it can be used in a single stand-alone setup as well. Clocks and triggers are programmed and generated by a master module and distributed in a multi-star topology. All triggers within the entire timing system are synchronized with a jitter of approximately 10ps.


In addition to the distribution of triggers and clocks the system is able to distribute data words and tables through its fiber distribution network. A precision 1.3GHz clock with modulated data is used on the fiber links. Receivers can recover both clock and data. Synchronized dividers are used to generate local clocks at the receivers. The receiver has 23 programmable outputs:
  • Trigger with delay
  • Immediate or delayed trigger events
  • Gates between trigger events
  • Slow clocks
  • Two different slow data protocols
  • Fast data protocol

  • 3x RJ45 outputs at front panel with 2 triggers and one precision clock as LVDS signals
  • trigger position: 0 .. 160ms delay, 1ns resolution
  • trigger width: 0 .. 160ms, 10ns resolution
  • up to 255 trigger event numbers
  • precision clocks: 2.5 .. 650MHz
  • optional RTM with up to 9 additional triggers
  • optional RTM with up to 9 fiber links
  • clock and trigger jitter: ~10ps RMS
  • transmitter is implemented on a piggyback with 3 channels with or without drift compensation (order option)

Optional RTMs:
  • up to 9 drift compensated transmitter outputs on SFP modules.
  • 9 triggers and clocks on LVDS (RJ45 plugs) and LEMO connectors. Three of these outputs will provide a ps shift of the falling and leading edges.
