Frequency Accuracy
The output frequency accuracy during the free run of the NE
clock is better than +4.6 × 10
The frequency stability in the holdover mode is: Frequency
deviation ≤ 0.37 × 10
Frequency Capture and Out-of-lock
Range
The minimum frequency capture and out-of-lock range are: ±4.6
-6
× 10 .
Synchronization Clock Source
It can be obtained from the following types of input:
2,048 kHz synchronization clock input and 2,048 kbit/s
synchronization clock input. 2,048 kbit/s is preferred as the
default upon power-on. The 2,048 kbit/s synchronization
clock signal complies with Recommendation G.704.
Recover timing from the STM-N signals.
