PIN DESCRIPTION
NOTES:
1.0
Operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions is not implied. Exposure to
Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
2.0
Power-on Reset will activate within the stated range
3.0
Ref- GR1244-CORE 3.2.1 R3-1.
4.0
Holdover stability is the cumulative fractional frequency offset containing Initial Offset, Temperature, and Drift components as described by
Bellcore GR-1244-CORE 5.2.
5.0
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.
6.0
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.
