SY01-S3T
Date: April 1 , 2002
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.
INTRODUCTION
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)
The SY01-S3T performs clock regeneration as a Synchronous Equipment Clock (SEC), or STRATUM 3 in ATM, SDH,
PDH, and SONET networks. It is designed for manufacturers of network equipment, especially Access Switches, Core
Switches, Cross Connects, Digital Multiplexers-Exchangers, and SDH/SONET equipment. The unit is also suitable for
PCS, WLL, and Wireless Base Stations. Wherever a Timing unit with high performance specifications is required, the
SY01-S3T can be integrated into the network system and provide all necessary frequencies and interfaces. The input
stage can receive two different input reference signals at various rates from 4 kHz to 77.76 MHz. An optional
