DC1941B, Demo Board Using LTC6820 isoSPI 2-Wire Serial Interface
Diseño de referencia por: Analog Devices
DC1941B, Demonstration Circuit is an isoSPI transceiver board based on LTC6820. The LTC6820 provides a method of interconnecting standard serial peripheral interface (SPI) devices using a single twisted pair of wire up to 100 meters of distance, with full galvanic isolation. This proprietary 2-wire interface is called isoSPI and the LTC6820 encodes SPI signals, up to 1Mbps, into a differential isoSPI signal. The isoSPI signal can then be transmitted across a simple pulse transformer through a twisted pair, where an isoSPI receiver decodes the transmission and recreates SPI signals
