PT7A4409/4409L

T1/E1/OC3 System Synchronizer

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Features

Description

• Supports AT&T TR62411 Stratum 3, 4 and

Stratum 4 Enhanced for DS1 interfaces and for

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

13 for E1 interfaces

PT7A4409/4409L 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

The PT7A4409/4409Lmeets the requirements forAT&T

TR62411 Stratum 3, 4 and Stratum 4 Enhanced, and ETSI

ETS 300 011 in jitter tolerance, jitter transfer, intrinsic

jitter, frequency accuracy, holdover accuracy, capture

range, phase slope and MTIE, etc.

•

Provides five kinds of 8kHz ST-BUS framing

signals

•

Two independent reference inputs

Input reference frequency 1.544MHz, 2.048MHz

or 8kHz selectable

•

Provides bit error free reference switching and

meets phase slope and MTIE requirements

Normal, Holdover or Free-Run operating modes

available

The PT7A4409/4409Loperates in Manual orAutomatic

Mode, and in each of the modes, three operating states

are available: Normal, Holdover and Free-Run.

•

Automatic reference input impairment monitor

Power supply: 5V (4409) and 3.3V(4409L)

Applications

Ordering Information

• Synchronization and timing control for multitrunk

T1 and E1 systems, STS-3/OC3 systems
