Short Content: Abstract: ADl871 is 105dB which, the 96kHz high performance stereo sound 24 ∑-ΔA/D switches AnalogDevices Corporation produces. Because is the serial output, therefore, when it uses in high speed data gathering, if direct clever microcomputer (MCU) is connected, the sampling speed will reduce greatly. Therefore, has designed between ADl871 and the MCU connection with scene programmable gate array (FPGA), has solved this problem. Gave and has carried on the simulation with the VHDL language design interface circuit and the procedure.Key ...
