JITTER SPECIFICATIONS
The ADN2812 CDR is designed to achieve the best bit-error-
rate (BER) performance and exceeds the jitter transfer, genera-
tion, and tolerance specifications proposed for SONET/SDH
equipment defined in the Telcordia Technologies specification.
Rev. 0 | Page 13 of 28
Jitter is the dynamic displacement of digital signal edges from
their long-term average positions, measured in unit intervals
(UI), where 1 UI = 1 bit period. Jitter on the input data can
cause dynamic phase errors on the recovered clock sampling
edge. Jitter on the recovered clock causes jitter on the
retimed data.
The following sections briefly summarize the specifications of
jitter generation, transfer, and tolerance in accordance with the
Telcordia document (GR-253-CORE, Issue 3, September 2000)
for the optical interface at the equipment level and the
ADN2812 performance with respect to those specifications.
JITTER GENERATION
The jitter generation specification limits the amount of jitter
that can be generated by the device with no jitter and wander
applied at the input. For OC-48 devices, the band-pass filter
has a 12 kHz high-pass cutoff frequency with a roll-off of
20 dB/decade, and a low-pass cutoff frequency of at least
20 MHz. The jitter generated must be less than 0.01 UI rms, and
must be less than 0.1 UI p-p.
JITTER TRANSFER
The jitter transfer function is the ratio of the jitter on the output
signal to the jitter applied on the input signal versus the
frequency. This parameter measures the limited amount of the
jitter on an input signal that can be transferred to the output
signal (see Figure 15).

JITTER TOLERANCE
The jitter tolerance is defined as the peak-to-peak amplitude of
the sinusoidal jitter applied on the input signal, which causes a
1 dB power penalty. This is a stress test intended to ensure that
no additional penalty is incurred under the operating
conditions (see Figure 16).
