DEVICE

SPECIFICATION

S3040A

SONET/SDH CLOCK RECOVERY UNIT

BiCMOS PECL CLOCK GENERATOR

FEATURES

GENERAL DESCRIPTION

The function of the S3040 clock recovery unit is to

derive high speed timing signals for SONET/SDH-

based equipment. The S3040 is implemented using

AMCC’s proven Phase Locked Loop (PLL) technology.

•

Micro-power Bipolar technology

Complies with Bellcore, and ITU-T specifica-

tions for jitter tolerance, jitter transfer and

jitter generation

The S3040 receives an OC-48/STM-16 scrambled

NRZ signal and recovers the clock from the data.

The chip outputs a differential bit clock and retimed

data.

•

On-chip high frequency PLL with internal

loop filter for clock recovery

Supports clock recovery for OC-48/STM-16

(2488.32 Mbit/s) NRZ data

The S3040 utilizes an on-chip PLL which consists

of a phase detector, a loop filter, and a Voltage

Controlled Oscillator (VCO). The phase detector

compares the phase relationship between the VCO

output and the serial data input. A loop filter con-

verts the phase detector output into a smooth DC

voltage, and the DC voltage is input to the VCO

whose frequency is varied by this voltage. A block

diagram is shown in Figure 2.
