Digital Radio Block Diagram

As you can see, this baseband processor performs the packet stream decoding, as well as channel and source decoding which usually requires an additional processor.

320AIC23

The 320AIC23 is an integrated CODEC and amplifier IC, which drives a pair of headphones. Integrating the CODEC and amplifier into one package reduces the component count and board space requirements. The IC exhibits 100 dB SNR, and has programmable gain amplifiers. The headphone amplifier provides 30 mW output, and the maximum sample rate is 96 kHz.

SST 39VF400A 4 Mbit Flash Memory

The DR101 uses a flash memory IC to store the firmware and operating system of the radio, and it operates on 2.7 V.
