For new designs we recommend the SIG60 and SIG61 devices

UART Over Powerline Transceiver - SIG40

Datasheet

The SIG40 transceiver modem enables UART / LIN asynchronous multiplex communication networks to operate over battery power-line, using original signaling technology. It provides a new economical physical communication transceiver for asynchronous protocols, overcoming the hostile environment over the vehicle battery power-line. When implemented in a LIN-bus network over the powerline, the SIG40 replaces the LIN-bus transceiver and the LIN-bus data wire. Its data rate triples the LIN transfer rate. The SIG40 saves node costs and increases the network capacity. More than one network can operate over the same line, using different carrier frequencies A sleep mode enables power saving. Wakeup messages over the DC powerline awaken remote devices as required by the LIN-bus protocol. The SIG40 can be economically integrated with other CMOS applications such as micro controllers.

Features Innovative power line transceiver for low cost UART or LIN over powerline network. Allows to increase LIN bus bit rate up to 57.6 Kbps. The multiplex network operates over wide battery power line. Economical - Small gate count CMOS semiconductor. Replaces a UART / LIN bus transceiver. Eliminates the UART / LIN bus control wire. Sinus wave modulation narrow band carrier - less EMC Multiple independent networks can share the same power line by using different carrier frequencies.
