基于DSP双通道高速数据采集卡的设计

The Design of Dual Channel High Speed Data Acquision Card Based on DSP

针对采集高频扰动信号的需要,本文介绍了一种由DSP芯片TMS320VC5509和两片8位并行高速A/D转换芯片TL C5510组成的双通道高速数据采集卡。经过实测,该卡的的数据采集速度可以达到20MSPS。利用该数据采集卡,可以采集高频扰动信号并存储采集到的数据。

In order to gather the high frequency in terferential signal this paper introduce a high speed data acquisition card DSP named TMS320VC5509 which is a 8 bits parallel ND chip compose of the system. According to practical measure, the card＇s acquisition speed can achieve 20 Msps .We can use the card to gather the high frequency interferential signal and save the gathering data.
