DCB1M IC - DC power line transceiver

Enables SPI, UART, DMX512, RDM and I2C data networks over Power Line

The DCB1M IC is for communication networks over noisy DC power lines at bit rates up to 1.4Mbit/s. Transfering UART, SPI, DMX512 RDM, and I2C protocols. The IC has built-in error correction codes for communication robustness. and CSMA/CA arbitration mechanism for multiplex networks.

Description

The DCB1M IC operates as a transceiver for message communication, allowing multi-master network topology. The device is designed to operate over noisy power lines.

The device interfaces with UART, SPI, DMX512, RDM, and I2C protocols. The entire firmware is implemented in a small-size ASIC. Its IP can be implemented in the customer's own IC design, such as the Internet of Things (IoT) sub-network.

 

Operation

The DCB1M building blocks are divided into the following blocks:

  • Protocol handling block interprets the host protocol.
  • Transmit and Receive internal FIFOs, each has 1k bytes as a buffer between the host and the DC-BUS power line.
  • CODEC block encodes/decodes the message using 3 levels of data protection according to channel noise conditions.
  • Modem block, modulate, and demodulate messages using a phase-shift keying scheme.
  • CSMA/CA mechanism add Carrier sense and arbitration capabilities to the device
  • Sleep mechanism ensures low power operation during sleep mode. The device senses the bus for a short period to detect possible wake-up messages from other devices connected to the power line.
