STRATUM 3 SIMPLIFIED CONTROL
TIMING MODULES (MSTM-S3)
DESCRIPTION
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.
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. Real-
time 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:
NOTES FOR TABLES 1-3
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.
3.0 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.
4.0 After 100 seconds at stable room temperature.
5.0 Consult factory for other output frequencies.

6.0 Ref- GR1244-CORE 3.2.1 R3-1.
7.0 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.
8.0 Add -T2 to model number.
9.0 Consult factory for power dissipation of -T2 (0 to +70 deg. C.) devices.
