HIGH FREQUENCY HITLESS SYNCHRONIZER - SY02-HLPL
PRELIMINARY SPECIFICATION
Date: July 1, 2002
• INTRODUCTION
The SY02-HLPL is a dual input reference hitless switching
device with high frequency crystal-based PLL synchronizer
designed as a subsystem module. Mainly used at high speed
Line Interface Cards in telecommunication products mainly
related to STN-n or OC-n. The SY02-HLPL is a
synchronization solution for timing and jitter topics specified
within ITU-T Recommendations G.813, ETSI -ETS 300 462-
4, and Bellcore GR-1244-CORE.
• FEATURES
- Low jitter output from intrinsically low jitter VCXO or VCSO;
- Two input references from 8KHz to 77.76MHz (See page 3 for options)
- One high frequency LVPECL output with enable/disable function up to 800MHz (pre-select frequency value –
See page 3 for options)
- Alarms and status;
