DUAL OUTPUT HITLESS SWITCHING - SY05-HLPL
Date: May 20, 2002
• INTRODUCTION
The SY05-HLPL is a high frequency clock that has been designed to
be use at high speed Line Interface Cards in telecommunication
products mainly related to STN-n or OC-n.
• FEATURES
√ A high frequency clock intended to be used at line cards for OC3 and OC12 (STM3 and STM12).
√ Along with SY0001 or SY05-HLPL provides complete timing solution.
√ Provides very low jitter output signal from 51.84MHz to 800MHz
√ Performs hitless switching between two reference signals
√ Supports four timing modes: (1) Free-run, (2) Locked to Reference 1 (3) Locked to Reference 2, and (4) Loop-
back timing.
√ Accepts reference inputs from two clock sources from 8kHz to 77.76MHz
√ Manual or Automatic selection between operating modes.
√ Alarm and status signals.
√ Complies with ITU-T Recommendations G.813, ETSI-ETS 300 462-4 and Bellcore GR-1244-CORE for Stratum
3 and 3E applications.
√ Small dimensions of 1.8 x 1.8 x 0.50 inch.
• APPLICATION
The SY05-HLPL high frequency clock can be used in ATM, SDH, PDH, and SONET networks devices. It is
designed for manufacturers of network equipment, especially Access Switches, Core Switches, Cross Connects,
Digital Multiplexers-Exchangers, and SDH/SONET equipment. The SY05-HLPL is a timing solution for Line
Interface Cards.
