PT7A4408/4408L

T1/E1/OC3 System Synchronizer

Features

Introduction

• Supports AT&T TR62411 Stratum 4 and

Stratum 4 Enhanced for DS1 interfaces and for

ETSI ETS 300 011, TBR 4, TBR 12, and TBR

13 for E1 interfaces

PT7A4408/4408L employs a digital phase-locked

loop (DPLL) to provide timing and synchronizing

signals for multitrunk T1 and E1 primary rate

transmission links, and for STS-3/OC3 links. The ST-

BUS clock and framing signals are phase-locked to

input reference signals of either 2.048 MHz,

1.544MHz or 8 kHz.

• Supports ITU-T G.812 Type IV clocks for

1.544kbit/s interfaces and 2.048kbit/s interface

•

Provides C1.5, C3, C2, C4, C8, C6, C16 and C19

output clock signals

Provides five kinds of 8kHz ST-BUS framing

signals

The PT7A4408/4408L meets the requirements for

AT&T TR62411 Stratum 4 and Stratum 4 Enhanced,

and ETSI ETS 300 011 in jitter tolerance, jitter trans-

fer, intrinsic jitter, frequency accuracy, capture range,

phase slope, etc.

Input reference frequency 1.544MHz, 2.048MHz

or 8kHz selectable

•

Normal or Free-Run operating modes available

Power supply: 5V (4408) and 3.3V(4408L)

The PT7A4408/4408L operates in Normal or Free-

run Mode.

Applications

• Synchronization and timing control for multitrunk

T1 and E1 systems, STS-3/OC3 systems
