One-way or two-way audio comm using RF transceiver and codec

Posted: 05 Jan 2011     Print Version  Bookmark and Share

Keywords:audio communications link  CC1110  CC2510 

This application note describes a versatile design that implements a one-way or two-way audio communications link between a 'Master' and a 'Slave', based on the Texas Instruments CC1110 or CC2510 system-on-

chip low power RF transceiver and the TLV320AIC26 codec. Full 16 bit ADC resolution is provided. Optionally, u-Law compression (to 8 bits) and expansion using a hardware implemented algorithm can be used.

The Codec EVM card is designed to accept a standard CC1110 EM card or CC2510 EM card. Alternate transceiver cards include a CC1110 and a low noise amplifier combination, a CC1110 and a power amplifier combination, and a CC2510 plus CC2590 'range extender' card (CC2510_CC2590 EM).
