ZL30342
SONET/SDH Low Jitter Line Card Synchronizer
Overview
The ZL30123 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. |

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
- 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
