Description

The MT9041B T1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for multitrunk T1 and E1 primary rate transmission links.

The MT9041B generates ST-BUS clock and framing signals that are phase locked to either a 2.048MHz, 1.544MHz, or 8kHz input reference.

The MT9041B is compliant with AT&T TR62411 and Bellcore GR-1244-CORE Stratum 4 Enhanced, Stratum 4, and ETSI ETS 300 011. It will meet the jitter tolerance, jitter transfer, intrinsic jitter, frequency accuracy, capture range and phase change slope requirements for these specifications.

Features

• Supports AT&T TR62411 and Bellcore GR-1244-CORE Stratum 4 Enhanced and Stratum 4 timing for DS1 Interfaces

• Supports ETSI ETS 300 011, TBR 4, TBR 12 and TBR 13 timing for E1 Interfaces

• Selectable 1.544MHz, 2.048MHz or 8kHz input reference signals

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

• Provides 3 different styles of 8 KHz framing pulses

• Attenuates wander from 1.9 Hz

Applications

• Synchronization and timing control for multitrunk T1 and E1 systems

• ST-BUS clock and frame pulse sources
