Two-way audio communications using the CC2510

Keywords:audio communications? CC2510 RF transceiver? two-way communications?

This application note describes a two-way audio communications link between a Master and a Slave, based on the Texas Instruments CC2510 SoC low-power RF transceiver. It operates in the 2.4GHz ISM/SRD band. It has been optimized for low cost, using a PCB folded dipole antenna and a minimum of external components. Several key features of the CC2510 are employed, including the internal ADC, the DSM (Delta-Sigma-Modulator) and (optional) ulaw compression/expansion algorithm implemented in hardware. These features eliminate the need for an external audio codec.

While the card described herein is based on the CC2510 and operates in the 2.4GHZ band, both the card and the software can be easily modified for use with a CC1110 operating in the 433MHz, 868MHz, or 915MHz bands.
