SY01-S3T

www.DataSheet4U.com SYNCHRONOUS EQUIPMENT TCXO BASED STRATUM 3 CLOCK UNIT – SY01-S3T SY01-S3T Date: April 1 , 2002 INTRODUCTION The SY01-S3T is an accurate time and frequency source that has been designed as a module level subsystem. The module is designed to work within ATM, SONET, SDH, and wireless systems where synchronization is vital. The SY01-S3T is an excellent TCXO based synchronization solution for timing, designed for Stratum 3 applications while maintaining certain features that can make it useful for, SONET Minimum Clock (SMC) or other kinds of system clocks. FEATURES An economically designed TCXO/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. Creates a history buffer for Holdover mode operation. Alarm and status signal. Host interface and JTAG port. Small dimensions of 1.80X1.80X 0.65 inch (open pkg) APPLICATION The SY01-S3T performs clock regeneration as a Synchronous Equipment Clock (SEC), or STRATUM 3 in ATM, SDH, ...
