8 / 19 page CC8520 WWW.TI.COM SWRS091A – MARCH 2010 8 Copyright © 2010, Texas Instruments Incorporated 2 SYSTEM DESCRIPTION The CC8520 is a 2.4GHz wireless SoC operating in the 2.4 GHz ISM band designed for streaming digital audio wirelessly. It is designated to operate autonomously (without any host MCU) but certain aspects of operation can be controlled by a host MCU. Before operation, the CC8520 must be programmed with a user-specific FW image, which can be created using the PPW Configurator [1]. The configuration file can be programmed into the on-chip Flash memory by using the PPW Configurator and the CC Debugger [2] and is also programmable in a production line. The configuration image contains information identifying the device as a master or a slave, how many channels are supported, the direction of the audio channels, HID support, audio device supported and more. If CC8520 is configured as a slave, it will automatically start searching for a valid audio network. If configured as a master, it will start a new network. As soon as a network is formed, audio transmission will commence. The CC8520 will automatically configure an attached supported audio IC (see compatibility list for a list of supported ICs in chapter 3). 3 SUPPORTED AUDIO DEVICES Supported ADC/DAC/Codec/Amplifier Devices The following device drivers will initially be implemented: Device DESCRIPTION AIC3101 Low-Power Stereo Codec with 6 Inputs, 6 Outputs, Speaker/HP Amp and Enhanced Digital Effects AIC3104 Low-Power Stereo CODEC with 6 Inputs, 6 Outputs, HP Amp and Enhanced Digital Effects ADC3101 92dB SNR Low-Power Stereo ADC with Digital Mic Support AIC3204 AIC3204: Very Low-Power Stereo Audio CODEC with Power Tune™ Technology Note: The complete list of supported devices can be found in the PPW Configurator [1]. Supported SPDIF-RX / SPDIF-TX / DSP Devices The following device drivers will be implemented: Device DESCRIPTION DIR9001 96 kHz, 24-Bit Digital Audio Interface Receiver DIT4096 96 kHz, Digital Audio Transmitter DSP Generic Digital Audio Device Note: The complete list of supported devices can be found in the PPW Configurator [1]. Other audio devices The CC8520 is compatible with any I2S-based audio device that does not need to be configured at power-up and that is compatible with the requirements listed in the audio interface (Chapter 6). It is also compatible with a wide range of TI DSPs using an I2S interface. |
