OSA 3230 Cesium Clock The OSA 3230 as G.811 Reference Clock Source using Digital Cesium technology Features Performances exceeding ITU-T G.811 / Stratum 1 PRC Accuracy better than ±1x10-12 during entire life Long life 10 years cesium tube Extremely compact size — 3U high (5.24'') — less than 8” depth, compatible with ETSI and 19'' standards Front or Rear access connectors (depending on configuration) Single 10 MHz output Programmable 1 / 5 / 10 MHz TTL output Redundant DC power supply inputs Remote control and monitoring via RS232 (fully manageable locally and remotely) using SyncView Plus management system. Optional Ethernet Timing output module Telecommunication networks require highly accurate clocks for the effective transmission of digital signals. One of the primary objectives of telecommunication networks is to guarantee, at the connection between different networks, a slip rate of less than one slip in 72 days. Meeting these stringent specifications requires the implementation of a Primary Reference Clock (PRC) that must generate signals with an accuracy better than 1E-11, at all times. Generally, this is achieved using Cesium clock technology, often combined with GPS receivers as backup sources. Unlike off-air receivers, Cesium clocks are autonomous, self-contained primary references immune from external influences. Highlights The OSA 3230 Cesium Clock is specifically designed and produced with the latest technology to serve complex applications where an extremely accurate reference signal is needed in a minimum size. The OSA 3230 Cesium Clock offers a unique set of operational features and performance, including greatly enhanced and easy integration into industrial, professional time and frequency host systems. With its long life cesium tube, the OSA3230 will meet the requirements where G.811 performances are needed over a long period of time.
