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.

Description

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

DEVICE INTERFACE

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

SIGNALING TECHNOLOGY

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.

SLEEP MODE

The device has a sleep mode for power saving, where its power line sensing allow wakeup from messages imitated by other devices. The SIG60 device can interface directly to a LIN host, hence eliminating the LIN transceiver.

BIT RATES

The SIG60 can reach bit rates of up to 115.2Kbps allowing to increase the LIN bus bit rate of up to 5 times faster than a traditional LIN network.

Operation

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.
