DC1941D

DC1941D is a LTC6820 isoSPI demonstration board. This demonstration circuit 1941 is an isoSPI™ transceiver board, based on Linear Technology’s LTC®6820. The LTC6820 provides a method of interconnecting standard serial peripheral interface (SPI) devices using a single twisted pair connection. This proprietary 2-wire interface is called isoSPI. The LTC6820 encodes SPI signals, up to 1Mbps, into a differential isoSPI signal which is transmitted via a simple pulse transformer through a twisted pair. At the other end of the twisted pair, the isoSPI signal can be translated back to SPI (using another LTC6820). Another option would be for the isoSPI to connect to a Linear Technology device with a built-in isoSPI interface, such as the LTC6804.

• It serves as a reference design for applications requiring isolated, long-distance SPI communication
