SY01-SMC SYNCHRONOUS EQUIPMENT SONET MINIMUM CLOCK

The SY01-SMC synchronization module is a Digital PLL (DPLL), which utilizes application specific software in the digital signal processor (DSP). The DSP is complemented by fast hardware logic (CPLD) where all multiplexers, counters, dividers, phase detectors, output frequency converters and other control logic circuits are completely implemented. The functi.

Features

A synchronization solution for timing, jitter and wander concerns in a single module. Complies with Bellcore GR-1244-CORE and GR-253-CORE for SMC applications. Supports four modes of operation: Locked to Reference 1, Locked to Reference 2, Holdover and Free-run. Accepts reference inputs from two independent sources from 8 kHz to 77.76 MHz. Provides two outputs 8KHz to 77.76 MHz. Loop filtering utilizing application specific software in the digital signal processor (DSP). Continuously monitors and evaluate input reference signals. Creates a history buffer for Holdover mode operation. Manual or .
