SYNCHRONOUS EQUIPMENT
STRATUM 3/3E CLOCK UNIT – SY10
Date: August 30, 2002
• INTRODUCTION
The SY10 - an accurate time and frequency source
that had been designed as a subsystem level
module. The module is designed to work within ATM,
SONET, SDH, and wireless systems where
synchronization is vital. The SY10 is an excellent
synchronization solution for timing, with jitter and
wander compliance per the specified within ITU-T
Recommendations G.812/G.813 and Bellcore GR-
1244-CORE. The SY10 is an enhanced version of
SY01 and is designed for Stratum 3 and Stratum 3E,
but also holds certain features that can make it
useful for SONET Minimum Clock (SMC) or other
kinds of system clocks.
v A synchronization solution for timing, jitter and wander concerns in a single module.
v Complies with ITU-T Recommendations G.812/813 and Bellcore GR-1244-CORE for Stratum 3 and Stratum
3E applications.
v Supports modes of operation: Locked, Holdover and Free-run.
v Accepts reference inputs from up to six independent sources from 8KHz to 77.76MHz
v Provides up to 3 output from 8KHz to 77.76MHz (Two user select and one fixed at 8KHz)
v Loop filtering utilizing specific software application in the digital signal processor (DSP).
v Continuously monitors and evaluate input reference signals.
v Phase build-out for output clock.
v Creates a history buffer for Holdover mode operation.
v Alarm and status signals and messages.
v Host interface SPI for configuring and remote monitoring.
v Supports Master/Slave configuration of two SY10 with minimum phase error between two clocks.
v Provides “hit-less” switching during switching between the clocks.
v Pin compatible with 18 pins SY01 module.
v Small dimensions of 1.82 x 1.82 x 0.7 inch. (0.60 inch with no mechanical cover)
• APPLICATION
The SY10, a Synchronous Equipment Clock (SEC), fulfills clock regeneration function for STRATUM 3 and 3E
equipment for: ATM, SDH, PDH, and SONET networks. It was designed for network system manufacturers such
as: 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 SY10 can be embedded within the network system and provide all
necessary frequencies and interfaces.
