The STM 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 STM enters the Free Run mode and signals an External Alarm. The STM 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 STM. 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. Control loop filters effectively attenuate any reference jitter and smooth out phase transients.

NOTES FOR TABLES 1-3 NOTES: 2.0 Holdover stability is the cumulative fractional frequency offset containing Initial Offset, Temperature, and Drift components as described by Bellcore GR-1244-CORE 5.2. Pull-in range is the minimum frequency deviation on the reference inputs to the timing module that can be overcome to pull itself into synchronization with the reference. After 100 seconds at stable room temperature. Consult factory for other output frequencies. Ref- GR1244-CORE 3.2.1 R3-1. A ‘1’ level indicates unit is within the extreme 10% of its operating range tracking the reference (~11ppm). Consult factory for use as a reference quilifier. Add ‘-T2’ to model number. Consult factory for power dissipation of -T2 (0 to +70 deg. C.) devices. Specifications subject to change without notice.
