Device Overview

Summary

The ZL30100 T1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization for multi-trunk T1 and E1 transmission equipment.
The ZL30100 generates ST-BUS and other TDM clock and framing signals that are phase locked to one of two input references. It helps ensure system reliability by monitoring its references for accuracy and stability and by maintaining stable output clocks during reference switching operations and during short periods when a reference is unavailable.
The ZL30100 is intended to be the central timing and synchronization resource for network equipment that complies with Telcordia, ETSI, ITU-T and ANSI network specifications.

Additional Features
  • Synchronizes to 8 kHz, 2.048 MHz, 8.192 MHz or 19.44 MHz input

  • Automatic entry and exit from freerun mode on reference fail
  • Provides DPLL lock and reference fail indication
  • DPLL bandwidth of 29 Hz for all rates of input references
  • Less than 0.6 nsecpp intrinsic jitter on all output clocks
  • 20 MHz external master clock source: clock oscillator or crystal
  • Simple hardware control interface
