ZL30109
Data Sheet
Description
The ZL30109 DS1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing
and synchronization for multi-trunk DS1 and E1 transmission equipment. The 19.44 MHz output makes the
ZL30109 also suitable for SDH line card applications.
The ZL30109 generates a 19.44 MHz clock and ST-BUS and TDM bus clocks 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 ZL30109 is intended to be the central timing and synchronization resource for network equipment that
complies with Telcordia, ETSI, ITU-T and ANSI network specifications.
