Abstract

A chip set has been designed for 10 Gb/s SDH-based optical transmission system and developed using GaAs gate array technology. The features supported by the chip set include 8:1 multiplexing and demultiplexing, frame alignment word insertion and detection, 32-bit parallel scrambling and descrambling, and B1 byte insertion and error detection. A parallel implementation of the STM overhead functions using TDM achieves a substantial decrease in operating frequency with only a small increase in gate complexity, hence it provides reduction of the power dissipation. This paper describes the architecture of the chip set, parallel circuit design technologies suitable for very high-speed SDH-based optical transmission system, and several of the chip set´s more interesting features
