Preliminary Specifications

M830 Series

12.249Gb/s OC-192 Clock & Data Recovery Transmitter Module

DESCRIPTION

The M830 Series CDR module is specifically

designed to regenerate the spectral clock

component from an incoming NRZ data stream,

incorporating forward error correction, and output a

low-jitter clock and retimed complementary data.

The module utilizes a phase-locked loop

architecture incorporating a high-stability, low noise

SAW VCO to provide extremely low jitter clock and

data outputs. The incoming data is frequency

doubled to recover the clock component. The

clock signal is then filtered by a microwave band

pass filter to remove wide band noise and spurious

signal. This signal is further filtered using the

FEATURES

narrow band SAW VCO based PLL to minimize the

noise close to the carrier. The low jitter clock is

then used to retime the data and serves as the

module’s clock output. The module provides user-

controlled clock phase shifter and output data

crossover adjustments to optimize system

performance.

Superior PLL-based jitter performance

8psec p-p jitter

0.9Vp-p complementary data outputs

1 Ul externally adjustable clock phase

200mVp-p input sensitivity

PLL lock-in range and loop transfer characteristics

are optimized for minimal jitter in accordance with

ITU and Bellcore standards for SONET/SDH

systems.

Optional adjustable bias @ data input to

decision circuit

Externally adjustable decision threshold
