Description:
The ZL30407 Clock Timing Integrated Circuits IC is a Network Element Phase-Locked Loop designed to synchronize SDH and SONET systems. In addition, it generates multiple clocks for legacy PDH equipment and provides timing for STBUS and GCI backplanes.
 
The ZL30407 operates in NORMAL (LOCKED), HOLDOVER and FREE-RUN modes to ensure that in the presence of jitter, wander and interruptions to the reference signals, the generated clocks meet international standards. The filtering characteristics of the PLL are hardware or software selectable and they do not require any external adjustable components. The ZL30407 uses an external 20 MHz Master Clock Oscillator to provide a stable timing source for the HOLDOVER operation. The ZL30407 operates from a single 3.3 V power supply and offers a 5 V tolerant microprocessor interface.
 
Specification:IC PLL SONET/SDH CLK MULT 80LQFP

 
Applications
• Synchronization for SDH and SONET Network Elements
• Clock generation for ST-BUS and GCI backplanes
