The ZL30119 SONET/SDH Line Card Synchronizer is a highly integrated device that provides timing and synchronization for network interface cards. 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.
Additional Features
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 that meet jitter requirements for interfaces up to OC-192/STM-64
Provides two DPLLs which are independently configurable through a serial peripheral interface
Programmable output synthesizers (P0, P1) 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
Provides 3 sync inputs for output frame pulse alignment
Generates several styles of output frame pulses with selectable pulse width, polarity, and frequency
Configurable input to output delay, and output to output phase alignment
