The SIG40 transceiver modem enables asynchronous LIN sub-bus and UART based multiplex communication networks over a single wire or a 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, the SIG40 replaces the LIN-bus transceiver and the LIN-bus data wire. Its data rate more than doubles the LIN transfer rate. The SIG40 saves node costs and increases the network capacity.
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.
Applications in wide range of consumer, avionics and vehicle modules such as doors, seats, mirrors, climate control, lights etc. The SIG40 contains a host and LIN-bus UART interface, DC power-line modem, line-driver and interface to low cost ceramic filters.
