CHARACTERISTICS
Performance
The S3040 PLL complies with the jitter specifications
proposed for SONET/SDH equipment defined by the
Bellcore Specifications: GR-253-CORE, Issue 2, De-
cember 1995 and ITU-T Recommendations: G.958
document, when used with differential inputs and out-
puts.
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 1 dB opti-
cal/electrical power penalty. SONET input jitter
tolerance requirements are shown in Figure 3.
The measurement condition is the input jitter am-
plitude which causes an equivalent of 1 dB 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 4.
The measurement condition is that input sinusoidal
jitter up to the mask level in Figure 3 be applied.
Jitter Generation
The jitter of the serial clock and serial data outputs
shall not exceed 0.01 UI rms when a serial data input
with no jitter is presented to the serial data inputs.
(See Table 3).
