Phase Lock Detector Synchronizes PLLs and Datacom Systems

Raltron Electronics Corp. has just announced the availability of its new Model SY13 Frequency and Phase Lock Detector. The unit is designed as an SMD packaged 8 pad component for integration into telecommuni-cations equipment. The unit is particularly suited for synchro-nization of optical networking equipment, PLLs, synthesizers, and other telecom applica-tions. The SY13 compares two external input signals and determines if they are synchro-nized in phase or in frequency. The module has been designed to show synchronization status (LVCMOS logic high) if the phase difference of the two signals is constant.
