CHARACTERISTICS
Performance
The SY87700V PLL complies with the jitter specifications
proposed for SONET/SDH equipment defined by the Bellcore
Specifications: GR-253-CORE, Issue 2, December 1995 and
ITU-T Recommendations: G.958 document, when used with
differential inputs and outputs.
Input Jitter Tolerance
Input jitter tolerance is defined as the peak-to-peak
amplitude of sinusoidal jitter applied on the input signal that
causes an equivalent 1dB optical/electrical power penalty.
SONET input jitter tolerance requirement condition is the
input jitter amplitude which causes an equivalent of 1dB
power penalty.

Jitter Transfer
Jitter transfer function is defined as the ratio of jitter on
the output OC-N/STS-N signal to the jitter applied on the
input OC-N/STS-N signal versus frequency. Jitter transfer
requirements are shown in Figure 2.
Jitter Generation
The jitter of the serial clock and serial data outputs shall
not exceed .01 U.I. rms when a serial data input with no
jitter is presented to the serial data inputs.
