SIG100 - UART/LIN TRANSCEIVER IC OVER DC POWER LINE
The next Generation byte oriented powerline transceiver - up to 115.2kbit/s
The SIG100 device merges both data and power over the powerline, eliminating the need for control and data wires.
The SIG100 is designed to meet the new DC-LIN ISO 17987-8, providing a seamless interface with LIN-BUS networks.
The SIG100 modulates UART/LIN bytes over DC powerline (DC-BUS). The SIG100 is an advanced generation of the widely used SIG60 device. Both devices use a unique multiplex digital signaling technology that overcomes the powerline noisy environment at bitrates up to 115.2Kbit/s. A Sleep mode allows low power consumption when the device is not used.
The SIG100 powerline transceiver reduces wiring in a wide range of automotive, aerospace, and industrial applications. These include networks for sensor readings, actuator activation, battery monitoring (BMS), doors, seats, mirrors, climate control, lights, Truck-Trailer communication, etc.
The SIG100 operates as a Master-Slaves network of multiple SIG100 . Users can define its own protocol since there is no limit to the number of UART bytes in a message. Furthermore, the SIG100 operates on any selectable carrier frequency between 5MHz and 30MHz with 100 kHz spacing, allowing multiple independent networks to coexist on a single powerline by using different carrier frequencies for each network.
The Figure below depicts a typical SIG100 network, demonstrating a single byte transmission from SIG100 TX device to three SIG100 RX devices coupled through a capacitor to the same powerline. Upon detection of a start bit on the SIG100 TX device HDI pin, a modulated PLC-byte transmission starts. Then, the modulated PLC-byte is decoded back to a byte-field on SIG100 RX devices' HDO pin at a fixed latency of ~2.5 bits.
