摘要
本文采用美国国家半导体公司的高速双通道模数转换器(ADC08D1000),以及Altera公司CycloneII系列的FPGA(EP2C70F896C8)实现对双路信号的高速采样,每片ADC通过交叉采样对每路信号的采样率达到2GSPS。本文着重介绍电路的设计,以及PCB制版过程当中的技巧问题。
In this paper, a high speed dual ADC(ADC08D1000) produced by National Semiconductor and an FPGA (EP2C70F896CS) in CycloneⅡ series of Altera are used to sampling two signals in the same time , and each converter is interleaved to increased the sample rate up to 2GSPS. Here our emphases are on some tips on design of the cirsuit and PCB board.
