SY01-S3F
Date: April 20 , 2002
The SY01-S3F 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-S3F is an excellent OCXO based synchronization
solution for Stratum 3 applications with an additional +/-4.6PPM
free-run TCXO.
INTRODUCTION
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
.
Provides a secondary free-run output within +/-4.6PPM
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-S3F 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-S3F 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
application can be achieved by integrating the SY01-S3F with a low cost GPS receiver and locking it to the GPS 1
pps output signal.
