Design and Test of High Speed Digitization Sampling Circuit Based on FPGA

To sample wideband IF signal with large amounts of data, a high-speed data acquisition program is presented. The program focus on circuit design, issues that need attention, and high-speed sampling signal deceleration strategy. The 2.4GHz rate sampling data acquisition, reception and demux are completed with ADC083000 and Field-Programmable Gate Array (FPGA). At last, a result of sampling with the converter is offered by chipscope software. The result verified ADC083000 has an excellent performance with more than 6.5 bit ENOB and good phase coherence. In engineering practice, the design has been used and has good performance.
