Bluetooth, WiFi, other 2.4GHz devices
• Fast time-to-market– No SW development required – audio
protocol built in– Applications designs provided– Easy-to-use designers’ tool
• Flexible, low cost solution– Seamless connection and control of selected TI audio codecs,
DACs/ADCs and digital audio amplifiers using I2S and I2C – Data channel (for example, remote control)– A platform that enables multiple applications
PurePath FW Releases
• 1.0 – (June 2010)– Audio I/O – I2S– 1 Master– 1 Slave– Omni directional from master to slave
• 1.1 – (June 2011)– Audio I/O – I2S– 1 Master– 2 Slave– Omni directional from master to slave’s
• 1.2 – (August 2011)– Audio I/O – I2S– 1 Master– 2 Slave– Bi-directional from master to slaves and slaves to master

• Lets you evaluate CC8520 for wireless audio applications; audio interfaces include:
• S/PDIF optical + coax input/output
• line input/output, headphone output
• microphone input
• A TLV320AIC3101 audio codec is mounted on the Audio EB board -- but also has connectors to plug into most TI Codecs
