General Description

The DMR01 is a micro power receiver chip for low frequency data transmission systems. Based on a 32 kHz clock source, 8 different carrier frequencies from 8.192 kHz to 122.88 kHz are possible. Depending on the transmit distance and the transmit time, the DMR01 works with 4 different data rates from 1 to 8 kBaud. The DMR01 is able to receive coded data with a maximum length of 128 bit for each transmit package. The DMR01 uses a seriel SPI register for an easy communication with external microcontrollers. Features like input amplifier gain, ADC sensitivity, data rate, selection of coded or uncoded data are programmable via the SPI interface.
