The TFD8000 is a militarized time and frequency system has been qualified to rigorous military standards and uses modular construction to ensure complete flexibility and easy maintenance.  The TFD8000 is the US Navy’s program of record Time and Frequency Distribution System (TFDS) and is fully supported by the Navy’s supply system.  Single, dual and triple redundant models are available.  Over thirty standard options are available.  Oven controlled and Rubidium time bases are available. Both types are disciplined to the GPS satellite system.

Rugged, Highly reliable, extremely flexible, great features, AN/BSQ-9(V) is shipboard qualified.

The TFD-8000 is the flagship of the Brandywine Communications fleet. It is a highly reliable, extremely flexible time and frequency source. Reliability and maintainability are features that were "designed in" to the Brandywine Communications TFD-8000, not added on.

Applications include Master Clock for ships and submarines, Military Secure Communication (C4I), Test Range primary time and frequency standard, Communications satellite ground station support, standards and calibrations laboratories.

The TFD8000 is composed of a chassis/backplane and a large library of plug-in features that include:

  • Frequency Synthesizers
  • SA-ASM or CA code GPS receivers
  • Network Time Protocol (NTP) Time Server
  • Status Alarm Monitor
  • Quartz, Rubidium, Cesium Oscillator choices
  • Time Code Outputs
  • Dual/Triple redundancy with Automatic Switchover
  • Hot Swappable Modules
  • 1-5-10 MHz Outputs
  • T1/E1 Frequency Outputs

The outputs of the TFD-8000 are fully compatible with other Brandywine Communications products such as Computer Clock Synchronization boards, Frequency Distribution Amplifiers, and Video Annotators as well as industry standards such as T1, IRIG and IEEE.
