Description
The MT9040 T1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for T1 and E1 primary rate transmission links.

FEATUREs
• Supports AT&T TR62411 and Bellcore GR-1244- CORE and Stratum 4 timing for DS1 interfaces
• Supports ETSI ETS 300 011, TBR 4, TBR 12 and TBR 13 timing for E1 interfaces
• Selectable 19.44 MHz, 1.544MHz, 2.048MHz or 8kHz input reference signals
• Provides C1.5, C2, C4, C6, C8, C16, and C19 (STS-3/OC3 clock divided by 8) output clock signals
• Provides 5 different styles of 8 KHz framing pulses
• Attenuates wander from 1.9Hz
• Fast lock mode
• JTAG Boundary Scan

APPLICATIONs
• Synchronization and timing control for multitrunk T1 and E1 systems
• ST-BUS clock and frame pulse source
