SPECIFICATION

S3029

SONET/SDH/ATM 155 MBIT/S QUAD TRANSCEIVER

BiCMOS PECL CLOCK GENERATOR

SONET/SDH/ATM 155 MBIT/S QUAD TRANSCEIVER

GENERAL DESCRIPTION

FEATURES

The function of the S3029 clock synthesis and recov-

ery unit is to derive high speed timing signals for

SONET/SDH-based equipment. The S3029 is imple-

mented using AMCC’s proven Phase Locked Loop

(PLL) technology.

•

Complies with ANSI, Bellcore, and ITU-T

specifications for jitter tolerance, jitter generation

Five on-chip high frequency PLLs with

internal loop filters for clock recovery

Supports clock recovery for STS-3/STM-1

(155.52 Mbit/s) NRZ data

Clock Multiplier PLL for transmit clock

generation

19.44 or 51.84 MHz reference frequency

Lock detect—monitors run length and

frequency

•

The S3029 receives four STS-3/STM-1 scrambled NRZ

signals and recovers the clock from the data and

generates a 155 MHz transmit clock. The chip out-

puts a differential PECL bit clock and retimed data.

Figure 1 shows a typical network application.

•

Low-jitter differential interface

3.3V supply

Available in a 64-pin TQFP package

Compatible with IgT WAC-413 ATM Quad-

UNI processor

The S3029 utilizes five on-chip PLLs which consist of

a phase detector, a loop filter, and a voltage con-

trolled oscillator (VCO). The phase detector

compares the phase relationship between the VCO

output and the serial data input. A loop filter converts

the phase detector output into a smooth DC voltage,

and the DC voltage is input to the VCO whose fre-

quency is varied by this voltage. A block diagram is

shown in Figure 2. There is a single clock multiplier

PLL which generates a 155 MHz transmit clock from

a 19.44 or 51.84 MHz input.
