JITTER SPECIFICATIONS

The ADN2812 CDR is designed to achieve the best bit-error-

rate (BER) performance and exceeds the jitter transfer, generation,

and tolerance specifications proposed for SONET/SDH equip-

ment defined in the Telcordia Technologies GR-253-CORE

document.

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, jitter transfer, and jitter tolerance in

accordance with the GR-253-CORE from Telcordia 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 vs. 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 to ensure that no addi-

tional penalty is incurred under the operating conditions (see

Figure 16).
