Framer T1/E1 5V 28-Pin PLCC T/R

The MT9041B T1/E1 System Synchronizer contains adigital phase-locked loop (DPLL), which providestiming and synchronization signals for multitrunk T1and E1 primary rate transmission links.The MT9041B generates ST-BUS clock and framingsignals that are phase locked to either a 2.048 MHz,1.544 MHz, or 8 kHz input reference. The MT9041B is compliant with AT&T TR62411 andBellcore GR-1244-CORE Stratum 4 Enhanced,Stratum 4, and ETSI ETS 300 011. It will meet the jittertolerance, jitter transfer, intrinsic jitter, frequencyaccuracy, capture range and phase change sloperequirements for these specifications.

• 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 1.544 MHz, 2.048 MHz or 8 kHz 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
