Brandywine - Modular Master Clock

Product Overview:

  • Redundant design with multiple signal paths built in for high-availability.
  • The modular design is highly adaptable and can be field-upgraded, allowing a future-proof solution
  • 12 expansion slots in the 2U version and 6 expansion slots in the 1U variant.
  • Ideal for applications that require an unusual mix of interfaces
  • Unique optical crosslink architecture for either Master-Slave hierarchical setups or Master-Master crosschecking and failover
  • 2U version is operated by an intuitive touch-screen interface, a first for any master clock system.
  • All key components are hot-swappable and are dual redundant.
  • The Output Signal modules are hot-swappable from the front, eliminating the need to disconnect cables.
  • Secure Management interface through SNMPv3 and encrypted password access from the front panel

More

Brandywine’s Modular Master Clock represents the next generation of modular timing systems.  Built on the highly successful High Performance Timing System, the Modular Master Clock is a leap forward in design.

At the center of the system are Brandywine’s powerful dual-redundant Master Clock Modules (MCM), which are capable of receiving time from a GPS signal, either from an internal SAASM or standard CA code receiver, or external reference sources, such as IRIG-B, 1PPS, 10 MHz or HaveQuick.

The output signals for the Modular Master Clock are generated by up to 12 hot-swappable Output Signal Modules (OSM), and are ideal for custom solutions or future expansion. Available modules include NTP module, Analog Low-Phase-Noise frequency module, IEEE-1588 PTP module, time code modules such as IRIG A, B, G, H, and NASA 36, Pulse Rates, PTTI, as well as an optical crosslink module.
