.. SYNCHRONOUS EQUIPMENT OCXO BASED STRATUM 3 CLOCK UNIT - SY01-S3 - INTRODUCTION Date: May 20 , 2002 The SY01-S3 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-S3 is an OCXO based excellent synchronization solution for timing designed for Stratum 3 applications. - Features A Hardware/Software synchronization solution for timing, jitter and wander concerns in a single module. plies with ITU-T Remendations 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 k Hz 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-S3 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-S3 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 k Hz to 77.76 MHz. An optional application can be achieved by integrating the SY01-S3 with a low cost GPS...
