摘要
AD1871是AnalogDevices公司生产的105dB、96kHz高性能立体声24位Σ-ΔA/D转换器。由于是串行输出,故当其被用于高速数据采集时,如果直接和微型计算机(MCU)相连,采样速率会大大降低。为此,用现场可编程门阵列(FPGA)设计了AD1871和MCU之间的接口,解决了这一问题。给出用VHDL语言设计的接口电路和程序并进行了仿真。
The AD1781 produced by Analog Devices, Inc. is 24-Bit ∑-△ A/D converter for the highspeed industry data acquasition system.Because it is serial output, when it is connected with MCU, the sampling rate can not keep up with. The interface circuit between AD1871 and MCU is designed using VHDL and FPGA to resolve this problem. The program and emulation are given.
