High-speed Data Generator Data To Produce The Hardware Design

Data Generator can generate very complicated digital signals. It can be used as programmable data signal source in the fields of communication, radar, navigation, space, and so on.This work comes from the project "High Speed Data Generator" , which is taken on by the University of Electronic Science and Technology of China. This dissertation describes the design of the Data Generator, which includes data loading circuit, high speed data generating circuit and so on . It also analyzes some key techniques about its development and gives solutions of the high speed data generator. Author also presents the system structure of hardware and some test results. The main works of the dissertation include:1.Demonstrating the working process of the high speed data generator and the functions of its circuits, and giving the principle of the data loading circuit, generating circuit of high speed data and output control.2.With a view to the generation of the high speed data, this dissertation introduces the realization of the voltage level convertor and PS convertor which completes the conversion of parallel data to serial data of multi channel. It also discusses some key techniques such as the design of ECL circuit, high speed signal processing and external trigger control.
