Features

Introduction

• Meets jitter requirements for AT&T TR62411

Stratum 4 and Stratum 4 Enhanced for DS1

interfaces, and for ETSI ETS300 011 for E1 inter-

faces

PT7A4401C is functionally enhanced version of

PT7A4401B. It has better jitter performance and C16

whose output duty cycle is independent of 20MHz

master clock.

• Provides C1.5, C3, C2, C4, C8 and C16 output

clock signals

The PT7A4401C employs a digital phase-locked loop

(DPLL) to provide timing and synchronizing signals

for multitrunk T1 and E1 primary rate transmission

links. It generates the ST-BUS clock and framing sig-

nals that are phase-locked to input reference signals

of either 2.048MHz, 1.544MHz or 8kHz.

• Provides 3 kinds of 8kHz framing signals

• Selectable 1.544MHz, 2.084MHz or 8kHz input

reference signals

• Operates in either Normal or Free-Run states

• Enhanced in jitter and duty cycle comparing with

PT7A4401B

• Package: 28-pin PLCC (PT7A4401CJ)

The PT7A4401C is compliant with AT&T TR62411

Stratum 4 and Stratum 4 Enhanced, and ETSI ETS

300 011. It meets the requirements for jitter tolerance,

jitter transfer, intrinsic jitter, frequency accuracy, cap-

ture range and phase slope, etc.

Applications

• Synchronization and timing control for multitrunk

T1 and E1 systems

• ST-BUS clock and frame pulse sources
