Table 11: Clock Multiplier Unit Performance
(1)
These Reference Clock Jitter limits are required for the outputs to meet SONET system level jitter requirements
(< 10 mUIrms)
Needed to meet SONET output frequency stability requirements
(2)
Note: Jitter specification is defined utilizing a 12KHz - 5MHz LP-HP single pole filter.
