FDA-301 Point-to-Multi-Point Distribution Amplifier for Reference Frequency and Time Synchronization Signals

The Time & Frequency Distribution Amplifier FDA-301 is a very versatile fiber and coax Distribution Amplifier designed to distribute various signal types from a central frequency standard, and/or a central timing source, to multiple remote receiving points. It has a modular output design, with three output module slots at the rear, giving up to 18 fiber connections or 12 coax connections from a single unit.

  • FDA-301 also offers distribution of Time Synchronization signals via the Pulse inputs/outputs of for example 1-pps and unmodulated IRIG time code (DCLS). The pulse distribution is broadband, allowing any pulse input signal up to 1 MHz.
  • Furthermore, the FDA-301 has separate inputs for distributing serial (RS232) Time-of-Day messages (NMEA or user defined), which together with 1-pps pulse distribution will distribute a precise time scale.
  • All inputs are dual, in a master-slave configuration, with automatic change-over if the master fails, providing fail-safe input source redundancy.
  • FDA-301 has 3 output slots for various optional output modules. All coax and T.o.D. output modules have 4 connectors. All fiber output modules have 6 connectors.
  • The FDA-301 is designed to work with any Pendulum Frequency Standard (GPS-12R, 6688/89, GPS-88/89), any Fluke Frequency standard (908/909, 910, 910R) and with any reference clock from Orolia/Spectracom. It will also work with all other brands that produce a sine wave reference with amplitude between 0.2 and 2 Vrms.
  • The FDA-301 will accept all pulse sources producing a TTL or CMOS 5V signal, for example the 1-pps outputs of all Pendulum, Fluke and Orolia/Spectracom clocks.
