SIG102-IC

Overview

The SIG102 is a multi-I/O powerline transceiver designed for economical communication over noisy DC powerlines. It merges data and power transmission, eliminating the need for dedicated control wires. The device features eight configurable I/O ports that can operate as PWM outputs, ADC inputs, or digital I/Os. It supports master-slave network architectures where one master controls up to 255 slave devices. Communication utilizes a byte-oriented UART multiplex signaling modem with selectable bitrates ranging from 9.6 kbit/s to 115.2 kbit/s. Carrier frequencies are selectable between 5 MHz and 30 MHz in 100 kHz steps, allowing multiple networks on a single line. The component is housed in a compact QFN48 (7x7 mm) package.

Feature Summary

• Master-slave network architecture supporting up to 255 slave devices
• Eight configurable I/O pins functioning as ADC, PWM, or digital I/O
• Noise-robust communication via unique multiphase signaling modem
• Multiple independent networks operable on a single powerline using distinct carrier frequencies

Applications

• Renewable energy Nano-Grid systems
• Battery management systems (BMS)
• Climate control networks
• Sensors and actuators bus interfaces
• Lighting control systems

Procurement Notes

Verify the specific revision status of the datasheet DS-SIG102 R 0.90 prior to finalizing design specifications. Confirm that the required external components, such as the 16MHz crystal and 10.7MHz bandpass filter, match the manufacturer's recommendations for optimal performance. Ensure that the PCB layout adheres strictly to the provided guidelines to maintain signal integrity and electromagnetic compatibility.

Selection Notes

Select the SIG102 when reducing harness size by combining power and data lines is critical. Choose this device for applications requiring remote control of sensors and actuators without a central microcontroller. Consider the available carrier frequency spacing if multiple networks must coexist on the same powerline. Evaluate the sleep mode requirements to ensure low power consumption aligns with system operational cycles.

Part Context

The SIG102 belongs to Yamar's SIG100 series of powerline communication ICs. It is specifically engineered for DC powerline networking, distinguishing itself from AC-coupled solutions. The device complements other Yamar products like the SIG102-EVB evaluation board, which facilitates development and testing of the transceiver capabilities in practical network configurations.
