MT9045 - T1/E1/OC3 System Synchronizer

General Description

The MT9045 T1/E1/OC3 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for multitrunk T1 and E1 primary rate transmission links and STS-3/OC3 links.

Key Features

  • Supports AT&T TR62411 and Bellcore GR-1244CORE Stratum 3, Stratum 4 Enhanced and Stratum 4 timing for DS1 interfaces.
  • Supports ITU-T G.813 Option 1 clocks for 2048 kbit/s interfaces.
  • Supports ITU-T G.812 Type IV clocks for 1,544 kbit/s interfaces and 2,048 kbit/s interfaces.
  • Supports ETSI ETS 300 011, TBR 4, TBR 12 and TBR 13 timing for E1 interfaces.
  • Selectable 19.44 MHz, 1.544 MHz, 2.048 MHz or 8kHz input reference signals.
  • Provides C1.5,.
