ZL30101
Data Sheet
Description
The ZL30101 Stratum 3 System Synchronizer contains a digital phase-locked loop (DPLL), which provides
timing and synchronization for multi-trunk T1 and E1 transmission equipment.
The ZL30101 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 ZL30101 is intended to be the central timing and synchronization resource for network equipment that
complies with Telcordia, ETSI, ITU-T and ANSI network specifications.
