STM-S3 STRATUM 3 SIMPLIFIED CONTROL TIMING MODULES

The Connor-Winfield Stratum 3 Simplified Control Timing Module acts as a complete system clock module for general Stratum 3 timing applications. The STM is designed for external control functions. Full external control input allows for selection and monitoring of any of four possible operating state.

Features

enter other operating modes upon application of a proper control signal. Mode 1 operation (A=1, B=0) results in an output signal that is phase locked to the External Reference Input #1. Mode 2 operation (A=0, B=1) results in an output signal that is phase locked to External Reference Input #2. Holdover mode operation (A=1, B=1) results in an output signal at or near the frequency as determined by the latest (last) locked-signal input values and the holdover performance of the STM. Alarm signals are generated at the Alarm Output during Holdover and Free Run operation. Alarm Signals are also ge.
