Semiconductors that Save Wires

The Problem

Wires are bulky, heavy and unrelaible.

Reducing copper wires is a strategic goal of car-makers, aerospace framers and even smart cities lighting designers.


The Solution

Power Line Communication

Yamar’s DC-BUS innovative family of transceiver devices merge data/control lines over DC power lines to establish reliable multiplex UART, LIN, CAN-bus and SPI networks, addresses the EMI/EMC requirements.



DC-BUS devices for power line communication

SIG Family

UART and LIN transceivers over DC power lines at a maximum speed of 115.2Kbit/s using the unique signaling technology.


DC-BUS devices for power line communication

DCB Family

CAN, UART, SPI, I2C, DMX & RDM transceivers communicate over DC power lines at bit rates up to 1.4Mbit/s using the DC-BUS technology.
