DCB500 - Transceiver for
Product Overview Powerline Communication
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.
