| 摘要 |
The present invention relates to a serial peripheral interface (SPI) communications device removing noise generated between SPI communications. The SPI communications device includes an SPI master module; a line driver receiving and outputting the output of the SPI master module by removing noise from the output; and an SPI slave module receiving the output of the line driver. The line driver includes a differential driver receiving the output of the SPI master module and outputting the output with two signals and a differential line receiver receiving the two signals and modulating the two signals into one signal by removing the noise. |
