Description
Overview
Microsemi’s SyncSystem 4380A builds upon the legacy of the DVB SyncSource 4307A with a completely updated product design that uses high-end components and advanced algorithms to deliver world-class performance for the most demanding precise time and frequency applications.A Rubidium (Rb) atomic oscillator is combined with a high-performance Oven Controlled Crystal Oscillator (OCXO) and a semi-codeless dual band L1/L2 GPS receiver to provide excellent frequency and time accuracy, outstanding frequency stability, and very low phase noise.
Configurable and Scalable
BackThe 4380A is packaged in a 1U rack-mountable unit supporting hot-swappable input/output cards that provide configurability and scalability. The cards can be operated in any of the six card slots located at the rear panel of the unit, and the unit will automatically detect and configure the system based on the card(s) installed.Standard input/output card options for the 4380A include:
4394A Pulse Output
4395B-10 (10 MHz)
4395B-5 (5 MHz)
4395-1 (1 MHz)
4387A, 4387A-6V, 4387A-1V (Modulated IRIG/NASA36)
4337A Epoch Adjusted Timecode (AM)
4338A 6V/3V, Quad Am IRIG Output
4374A T1/E1 with DS1 Framing, 4 ports, RJ45
TOD Output, IEC 8271, 4 ports, RJ45
4393A Time Interval Counter (TIC) Input
4382A Phase Input Measurement (10MHz or 5MHz)
4383A IRIG Input (2 modulated IRIG input ports)
