SYNCHRONOUS EQUIPMENT DUAL OUTPUT HITLESS SWITCHING - SY05-HLPL
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) Loopback 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.

DESCRIPTION
The SY05-HLPL synchronization module is a high frequency PLL that performs hitless switching plus additional features necessary for timing at high-speed Line Interface Cards. The functional block diagram is shown in figure 1. The SY05-HLPL receives two reference signals, usually 19.44MHz and using PLL synthesizer generates a high frequency signal necessary for transceivers or framers. The PLL that is complemented by high-speed logic that provide processing, switching between the timing modes, alarm and status messages and etc. A high quality VCXO provides very low jitter at the output. The additional output is provided using a divider. The module supports two operating modes: AUTO mode is the mode where all switching are done automatically and MANUAL mode is where unit will switch according to the two external control pins CON1 and CON2. CON1 0 1 0 1 CON2 0 0 1 1 Operational mode Free-run (Unlocked) Locked to EX REF 1 Locked to EX REF 2 Locked to TLB REF
The module operates in the following four timing modes: 1) Free-run, 2) Locked to EX REF1, 3) Locked to EX REF2 and 4) Locked to TBL REF. Free-run it a mode the unit is unlocked to either of the inputs. The accuracy of the output frequencies in this mode is equal to the accuracy of free running VCXO. Locked to EX REF 1 is the mode where the output of the module is phase locked to input reference 1. Locked to EX REF 2 is the mode where the output of the module is phase locked to input reference 2, Locked to TBL REF is the mode where is the output of the module is phase locked to the signal used in Time Loop-back operation.
