The Design and Test of Eight -channel 1 Gsps Data Acquisition System

The design and test of an eight - channel 1 Gsps data acquisition system based on Flash ADC and FPGA (Field Programmable Gate Array) is introduced.The key points and difficulties of system design are the keystone of discussion,such as the generation and fan - out of 1 GHz clock signal,the capture and processing of 500 MHz source - synchronized data,the design of high speed PCB.Besides that the paper introduces the test of system,describes the test results of 1 GHz clock signal and the main performances of system.
