ZL30105
Data Sheet
Description
The ZL30105 SDH/PDH System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing
and synchronization for SDH and T1/E1 transmission equipment. It provides advanced support for systems
deploying redundant clocks.
The ZL30105 generates SBI, ST-BUS and other TDM clock and framing signals that are phase locked to one of
three network references or to a system master-clock reference. It helps ensure system reliability by monitoring its
references for frequency accuracy and stability and by maintaining tight phase alignment between the master-clock
and slave-clock outputs even in the presence of high network jitter.
The ZL30105 is intended to be the central timing and synchronization resource for network equipment that
complies with ITU-T, Telcordia, ETSI and ANSI network specifications.
