The ZL30121 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.

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 with jitter < 3 ps RMS suitable for GR-253-CORE OC-12 and G.813 STM-16 interfaces
• 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 AdvancedTCA^TM
• Configurable input to output delay and output to output phase alignment
• Optional external feedback path provides dynamic input to output delay compensation

Typical Applications

• AdvancedTCA^TMSystems
• Multi-Service Edge Switches or Routers
• Multi-Service Provisioning Platforms (MSPPs)
• Add-Drop Multiplexers (ADMs)
• Wireless/Wireline Gateways
• Wireless Base Stations
• DSLAM / Next Gen DLC
• Core Routers
