• * Features & Benefits
•
• + Synchronizes with standard telecom system references and synthesizes a wide variety of protected telecom line interface clocks that are compliant with Telcordia GR-253-CORE and ITU-T G.813
• + 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 synthesizer generates clock frequencies from any multiple of 8 kHz up to 77.76 MHz in addition to 2 kHz
• + Provides 3 reference inputs which support clock frequencies with any multiples of 8 kHz up to 77.76 MHz in addition to 2 kHz
• + Digital Phase Locked-Loop (DPLL) provides all the features necessary for generating SONET/SDH compliant clocks including automatic hitless reference switching, automatic mode selection (locked, free-run, holdover), and selectable loop bandwidth
• + Generates several styles of output frame pulses with selectable pulse width, polarity, and frequency
Description
AI
The ZL30122 SONET/SDH Line Card Synchronizer is a highly integrated device that provides timing and synchronization for network interface cards. The DPLL is capable of locking to one of three input references and provides a wide variety of synchronized output clocks and frame pulses.
