NETWORK ELEMENT TIMING GENERATOR STRATUM 3 SIMPLIFIED CONTROL TIMING MODULES (MSTM-S3-INT) PHONE (630) 851-4722 HTTP://WWW.CONWIN.COM DESCRIPTION MSTM-S3 PIN ASSIGNMENT The Connor-Winfield Stratum 3 Simplified Control Timing Module acts as a complete system clock module for general Stratum 3 timing applications. The MSTM is designed for external control functions. Full external control input allows for selection and monitoring of any of four possible operating states: 1) Holdover, 2) External Reference #1, 3) External Reference #2, and 4) Free Run. The table below illustrates the control signal inputs and corresponding operational states: In the absence of External Control Inputs (A,B), the MSTM enters the Free Run mode and signals an External Alarm. The MSTM will 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 MSTM. +5Vdc HOLDOVER EX REF 1 REF 1 GND EX REF 2 REF 2 FRERUN GND GND CLK_OUT ALARM OUT GND CNTL A SYNC_OUT CNTL B GND PLL TVL BOTTOM VIEW BLOCK DIAGRAM 0 Alarm signals are generated at the Alarm Output during Holdover and Free Run operation. Alarm Signals are also generated by loss-of-lock, loss of Reference, and by a Tune-Limit indication from the PLL. A Tune-Limit alarm signal indicates that the VCXO tuning voltage is approaching within 10% the limits of its lock capability and that the External Reference Input may be erroneous. A high level indicates an alarm condition. Realtime indication of the operational mode is available at unique operating mode outputs on pins 1-4.
