SIG100-IC

Overview

The SIG100 is a powerline transceiver that modulates UART and LIN protocol bytes over DC powerlines (DC-BUS), merging data and power transmission to eliminate separate control wires. It utilizes multiplex digital signaling technology to operate in noisy environments at bitrates up to 115.2 kbit/s. The device supports 251 selectable carrier frequencies between 5 MHz and 30 MHz, allowing multiple independent networks to coexist on a single powerline. It features backward compatibility with the SIG60 device and includes sleep modes for low power consumption. The component is housed in a QFN32 5x5 mm package.

Feature Summary

• Noise-robust UART/LIN transceiver designed for DC powerline communication
• Supports selectable bitrates from 9.6 kbit/s to 115.2 kbit/s
• Enables multiple networks on a single powerline via 251 selectable carrier frequencies
• Operates as Master or Slave in multiplex networks with no byte limit per message

Applications

• Vehicle sub-bus (LIN-BUS)
• Battery management systems (BMS)
• Climate control networks
• Sensors and actuators bus
• Truck-Trailer communication

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and temperature grade. Confirm that the required external components, such as the 16MHz crystal and 10.7MHz bandpass filter, are sourced separately as they are not included within the IC package. Ensure the design accommodates the necessary passive components for the powerline coupling interface.

Selection Notes

Select the SIG100 when wiring reduction is critical in automotive or industrial DC powerline applications. Choose this device if backward compatibility with existing SIG60 infrastructure is required. Verify that the application environment supports the required 3.3V logic levels and that the PCB layout can accommodate the QFN32 package and external filter requirements.

Part Context

The SIG100 represents an advanced generation of powerline communication devices from Yamar Electronics, succeeding the widely used SIG60 model. It maintains backward compatibility while offering enhanced flexibility through a wider range of selectable carrier frequencies and configurable bitrates. This evolution allows for more complex network topologies and improved noise immunity in electrically noisy DC powerline environments.

Replacement Considerations

The SIG100 is backward compatible with the SIG60 device when configured to specific carrier frequencies (5.5MHz, 6MHz, 6.5MHz, 10.5MHz, or 13MHz). A WRITE-REG command is required to enable this transparent communication mode.
