SIG60 IC – UART/LIN PLC Transceiver

BYTES TRANSFER OVER POWER LINE AT SPEEDS UP TO 115.2KBPS

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

SIG60 Interface

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.

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, with unique power line sensing, for wake-up message detection initiated by other devices.

Bitrate

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

LIN-Network

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.

Functionality

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.
