Extending SPI and McBSP With Differential Interface Products
Texas InstrumentsThe serial peripheral interface (SPI) and the multichannel buffered serial port (McBSP)provide serial communication between devices such as microcontrollers DSPs DACs andADCs. Typically these serial interfaces are single-ended and are in close proximity. Differential line circuits increase the allowable distance between devices while maintaining data integrity. This report describes RS-485
