DCB500 - Transceiver for

Powerline Communication

Product Overview

Description

The DCB500 is a transceiver for multiplex communication over noisy powerline in automotive and

avionics networks. The flexible protocol allows various applications such as transferring Data, Voice,

Compressed video (e.g. H.264) and music (e.g. MP3) between modules sharing a common DC

powerline at transfer rates up to 500Kbps.

The device is based on DC-BUS technology for multiplex network communication over noisy

powerline. It avoids complex cabling, saves weight, and simplifies installation. The device

communicates with its Host via Serial Peripheral Interface (SPI) or UART interface providing the user

the freedom to use his application-defined protocol.
