SONET MINIMUM CLOCK - SY01-SMC
Date: April 20, 2002
• INTRODUCTION
The SY01-SMC is an accurate time and frequency source that has
been designed as a module level subsystem for easy incorporation
into SONET/SDH systems or network elements. The SY01-SMC is an
advanced synchronization solution for timing, jitter and wander issues
in accordance with specification for SONET Minimum Clock (SMC)
given by BellCore GR-253-CORE and BellCore GR-1244-CORE.
• FEATURES
A synchronization solution for timing, jitter and wander concerns in a single module.
Complies with Bellcore GR-1244-CORE and GR-253-CORE for SMC 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 8KHz 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.
Manual or Automatic selection between timing modes.
Alarm and status signal.
Host interface and JTAG port.
Small dimensions of 2.0 x 2.0 x 0.55 inch.
• APPLICATIONS
The SY01-SMC performs clock regeneration as a Synchronous Equipment Clock (SEC), and is particularly designed
for SONET equipment and network elements. However, SY01-SMC can be used in any other telecommunication
equipment where synchronization is necessary if the performance allowed.
