Product Summary

Features

General Description

tions. The integrated frequency synthesizer provides continuous coverage from 10Mb/s to OC-48+FEC data

rates with SONET quality output. In addition to its broadband capability, the VSC8123 is designed for the most

demanding applications, where signal integrity is low and the absolute maximum voltage and timing margin is

required. The VSC8123 offers signal acquisition capabilities far beyond what conventional CDRs offer, in a

highly monolithic form.

its acquisition point in both voltage and phase. This enables the VSC8123 to acquire data in the presence of sig-

nificant symmetry distortion or “bad spots” in the data eye. Integrated voltage and phase adjustment is provided

to offset the sampling point over the entire voltage and phase range of the input data eye. Additional circuitry is

provided to measure relative bit-error rates without affecting the integrity of the active data stream. Using an

external controller, the VSC8123 can acquire frequency, scan the incoming data eye and automatically set its

position to optimize margin in both voltage and phase. This optimization can be one-time on power-up, or set to

continuously repeat without taking the data stream off-line—no errors will be introduced into the output data

stream as the chip tracks the center of the data eye.

eye and the quality of the acquisition without taking the data off-line, enabling eye profiling, Q-testing, signal

strength measurements, and bit-level error detection/prediction—all non-invasively.
