TFD-100 series

The TFD-100 series is a 1U, rack 19″ mount, modular time and frequency distribution unit. It provides the precise distribution of any frequency from 1PPS up to 10MHz include most popular standards: 1PPS (TTL), IRIG-DCLS (TTL/RS-422), 10MHz (TTL and Sine).

You can order the following base modules that differ in power supply:

  • TFD-101 – single 85-265VAC/100-370VDC power supply

  • TFD-110 – single 48VDC (36-75VDC) power supply
  • TFD-120 – dual, redundant 48VDC (36-75VDC) power supplies
  • FD-111 – dual, redundant 85-265VAC/100-370VDC and 48VDC (36-75VDC) power supplies
  • Available input modules:
  • TFM-1012 – two digital inputs (level TTL/50Ω) for 1PPS and 10MHz. Input sockets: BNC or SMA.
  • TFM-1022 – two switched, analog 10MHz (8 dBm) inputs for frequency distribution. Input sockets: BNC or SMA
