ZL30101 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...
