SY01-S3 SYNCHRONOUS EQUIPMENT OCXO BASED STRATUM 3 CLOCK UNIT

The SY01-S3 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 functio.

Features

A Hardware/Software synchronization solution for timing, jitter and wander concerns in a single module. Complies with ITU-T Recommendations G.813 and ETSI-ETS 300 462-4 and Bellcore GR-1244-CORE for Stratum 3 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 up to 77.76 MHz . Loop filtering utilizing application specific software in the digital signal processor (DSP). Continuously monitors and evaluate input reference signals. C.
