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 (fcr = (2n+1) x 8192
Hz, n = 0..7). 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 until with a maximum length of 128
bit for each transmit package. A frame detector gives the possibility to separate the data for different
applications. The DMR01 uses a serial SPI register for a simple data exchange with external
microcontrollers. Features like input amplifier gain, ADC sensitivity, data rate, selection of coded or uncoded
data are programmable via the SPI interface.
