基于LTC1865和McBSP的高速串行数据采集系统设计

Design of high speed serial data acquisition system based on LTC1865 and McBSP

介绍了16位串行模数转换芯片LTC1865与TMS320C2812芯片的多通道缓冲串口(McBSP)的工作原理。采用McBSP的时钟停止工作模式,将LTC1865通过光耦与McBSP直接相连,从而实现高速串行数据传输。

The principle of 16 bit analog-to-digital converter LTC1865 and multi-channel buffer serial port （McBSP） of TMS320F2812 are mainly introduced. Based on clock stop mode of McBSP,LTC1865 is directly connected to McBSP with optical coupler. In this mode, the serial data can be transfered high speed.
