NAMC-psTimer
Fast Timing System with pico-second Solution
Description
The NAMC-psTimer is an AMC based Fast Timing System with a pico-second stable clock for usage in the MicroTCA.4 architecture. Its main purpose is to output triggers and clock signals, which may be based on local stand-alone configuration, or information provided by a global timing system installation.
Intentionally, it 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
The number of output triggers and clock signals can be extended by adding an RTM, e.g. the NAMC-psTimer-RTM-C (copper).
