A Frame Synchronization System Using a Parallel Detection Method for the 565 Mb/s Optical Transmission System
565 Mb/s 광진속 시스템을 위한 병렬 검출방식을 이용한 프레임 동기 시스템
Abstract
A high speed frame synchronization system has been realized which generates the frame sync clock from 565Mb/s data stream (the DS-5 digital multiplex hierarchy signal). The design of a frame pattern detector using a parallel detection method brings into low speed operation and resolves the problems due to the high speed operation. The frame synchronization algorithm recommended by CCITT is also realized by designing a sync mode controller. Appropriate design procedures are considered for an efficient hardware design and minimized connection lines. The CAD simulation as well as experiment show that the performance of the newly designed frame synchronization system satisfies the relevant requirements.
