DCB1M evaluation board is used to test the DCB1M IC communication over DC noisy power lines such as of vehicles at speeds of up to 1.4Mbps.


The DCB1M Evaluation Board contains all the required firmware for operation as a DC power line transceiver.

The logic is implemented in a device that contains the modem and other logic required for its communication.

The built-in Analog-front-end consist of the analog circuitry, The board has line protection network and BPF filter required for the DCB1M ASIC operation.

A switching power supply provides the 3.3V required for the board operation from 10V to 35V DC power line.


The received phase modulated signal from the DC line passes through a protection network, input buffer and a passive filter to a comparator.

The device decodes the signal into bit stream message. The asynchronous or synchronous (UART/SPI) message output to the external host via JP1 HDO.

At the transmitter side, the external host input messages to the DCB1M device via JP1 HDI pin either as an asynchronous UART or synchronous SPI bit stream. The message is buffered into packets, protected against errors, modulated and conducted over the DC power line.
