Yamar developed unique modulation and algorithms for DC power line communication over noisy channels, implemented in low-cost semiconductors.

The IC devices provide a transparent physical layer using the powerline as media for data transfer with a seamless interface to common protocols such as UART, LIN, CAN, SPI, I2C, DMX.

Innovative technologies

Utilizing the DC-BUS IC devices

Signaling over power line

Unique modulation technique allowing robust byte by byte with built-in error protection communication.

Byte-oriented communication over DC lines

Transfer each byte separately enables a seamless interface with the LIN/UART protocols with unrestricted data message length.

Multi-channels over single cable

Multiple independent networks coexist over a single power line using different narrow-band carrier frequencies.

Message-oriented multi-master communication over noisy channels

Transfer code-protected messages with built-in CSMA and arbitration mechanism in a multi-master network using CAN, UART, and SPI protocols.

Technology description

Signaling modulation is based on combinations of multiple phase shifts. It proved to be reliable over noisy power lines networks. The UART/LIN communication solution allows even a single byte to be transferred on noisy channels.

Multiple networks communicate over a single power line allowing simultaneous operation of LIN, UART, CAN, and SPI networks, each using a different carrier frequency.

Target applications

The technology is designed to be robust for any application's powerline unpredictable characteristic, as in Industrial, LED, EV, medical, renewable energy, power solutions, avionics, agriculture, marine, and more.

The DC-BUS technology was mainly designed for DC power lines but is able to operate on dedicated AC lines seamlessly.
