INT
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.
