描述 Description

The ZL30116 SONET/SDH System Synchronizer is a highly integrated device that provides the functionality required for synchronizing network equipment. It incorporates two independent DPLLs, each capable of locking to one of eight input references and provides a wide variety of synchronized output clocks and frame pulses.

特性 Features

? Supports the requirements of Telcordia GR-253 and GR-1244 for Stratum 3, 4E, 4 and SMC clocks, and the requirements of ITU-T G.781 SETS, G.813 SEC, G.823, G.824 and G.825 clocks
? Internal APLL provides standard output clock frequencies up to 622.08 MHz that meet jitter requirements for interfaces up to OC-192/STM-64
? Programmable output synthesizers generate clock frequencies from any multiple of 8 kHz up to 77.76 MHz in addition to 2 kHz
? Provides 8 reference inputs which support clock frequencies with any multiples of 8 kHz up to 77.76 MHz in addition to 2 kHz
? Supports master/slave configuration for AdvancedTCATM
? Configurable input to output delay and output to output phase alignment
? Optional external feedback path provides dynamic input to output delay compensation
