Microchip Cesium Reaches A Higher Stability and Longer Life


The Microchip CsIII – Model 4310B-R is a lightweight, compact, economical cesium frequency standard. The technology developed for the CsIII is an evolutionary step forward in the quest for higher stability, lower phase noise and longer life. An ever-increasing base of demanding users in communications, timing, synchronization and other applications take advantage of this performance.
The 4310B-R is configured with 5 MHz and 10 MHz sinewave outputs, a 10 MHz TTL output, a 1PPS sync
input, and 5 x 1PPS timing output. All monitoring and control of the unit is done through the serial interface and Microchip’s proprietary Monitor3 software.

Packaged in a 2U, 19-inch rack-mounted chassis, the 4310B-R weighs less than 30 lbs.
The 4310B-R comes with a standard 1-year electronics warranty and an 8-year tube warranty. An optional extended warranty for the electronics may be purchased. The 4310B-R is ideal for Data Centers, SATCOM, Calibration, Metrology, and many other Test and Measurement applications that require cesium stability and accuracy.

Microchip’s 4310B cesium frequency standard is the smallest, lowest-power and most cost-effective cesium frequency reference available. It has a low-profile, 2U, 19-inch rack-mountable chassis and provides the same stability and accuracy as the standard-performance 5017A. Weighing less than 30 pounds, the 4310B is a portable solution for SATCOM applications and calibration services. The 4310B-R models are also fully CE compliant and provide a total of five 1 PPS outputs.
