SYNCHRONOUS EQUIPMENT HIGH FREQUENCY HITLESS SYNCHRONIZER - SY02-HLPL
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 4624, and Bellcore GR-1244-CORE.

DESCRIPTION
The SY02-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 the figure above . The SY02-HLPL receives two reference signals, from 8KHz to 77.76MHz (See page 3 for available options) 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 SY02-HLPL incorporates a High Frequency Phase Lock Loop has been designed to generate high frequency (up to 800MHz) output from a low jitter VCXO (Crystal Based Oscillator) or VCSO (SAW based oscillators). The output can be disabled externally by setting OUTEN pin high. The module supports a MANUAL operating mode where unit will switch according to a control pin CNT. During an event where the external reference signal disappears, the user instruct a reference change into the module through the control pin. The ALARM output signals monitor the status of the phase loop LOL (Loss of Lock) and LOR (Loss of Reference). If the reference REF IN is absent, the SY02-HLPL will automatically switch to free run mode and FRS output will indicate it. The SY02-HLPL is provided in an SMD package dimensions are 0.96x1.050 inch and power supply is 3.3V. - OUTPUT PROGRAMMING
