The SIG60 power line transceiver is capable to transfer any number of UART protocol bytes over the DC power lines at bit rates up to 115.2 Kbit/s. The IC operates both as a master or as a slave in a network of multiple SIG60 and SIG61 devices.


The SIG60 IC device communicates over the DC power line using UART protocol bytes at bit rates up to 115.2 Kbit/s.


The device simply interfaces with any UART / LIN port of any microcontroller (ECU). The power-line is used for both power and data communication, thus eliminating the need for special wires for carrying control or data.


The SIG60 uses a unique multiplex digital signaling technology that overcomes the power line noisy environment. The small footprint integrates most of the analog components needed for its operation. A capacitor interfaces the SIG60 signals to the power line.


The device has a sleep mode for power saving, with unique power line sensing, for wake-up message detection initiated by other devices.


The bit rates are selectable between 9.6 Kbit/s to 115.2 Kbit/s.


The SIG60 device can interface directly to a LIN host, hence eliminating the LIN transceiver. With bit rates up to 115.2 Kbit/s there is an increase of the LIN bus bit rate of up to 5 times faster compared to a traditional LIN network possible.


The SIG60 is byte oriented IC device.

Each byte that is entered to the device is modulated by a unique signaling modem and conducted via capacitor over the power line.

At the receive side, the byte is decoded and output to the external host after a fixed delay of 3.5 bits. any number of bytes can be transferred. It allows the user to define its own message protocol.
