225k ~ 1.4M Modem PSK 32-QFN (5x5)

The DCB1M is a device for multiplex communication over noisy power lines, at speed up to 1.4Mbit/s. The DCB1M is based on the DC-BUS™ technology for network communication between modules sharing a common DC or AC powerline. The device avoids complex cabling, saves weight, and simplifies installation. The DCB1M supports UART, SPI, DMX512, RDM, and I 2C protocols, enabling the user to meet this application protocol. Sleep mode allows low power consumption when the device is not used. A QFN32 5x5 mm package provides a small PCB footprint The DCB1M is beneficial for many applications ranging from LED, Aerospace, Automotive, Industrial, and even Toys.
