DESCRIPTION

QFN-40 PACKAGE (TOP VIEW)

The PurePath™ Wireless platform is a cost-

effective and low-power solution optimized for

wireless transmission of high-quality digital audio.

The CC8520 includes a robust built-in wireless

audio transmission protocol and can control

selected external audio devices. Utilizing

numerous coexistence mechanisms allows the

CC8520 to avoid interfering with, or being

interfered by other 2.4 GHz radio systems. The

CC8520, which supports 2 audio channels, is the

first device in the PurePath™ Wireless platform.

The CC8520 operates autonomously, and can be

used with or without an external MCU. An external

host processor can be connected through SPI and

control some aspects of its operation. The CC8520

interfaces easily with other TI audio ICs and DSPs

(using I2S and DSP/TDM interfaces).

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).

NETWORK TOPOLOGY AND NOMENCLATURE

A CC8520 network consists of one Protocol Master (PM) and one or two Protocol Slave(s) (PS). The PM

provides the audio reference clock and controls network association. The PS regenerate the audio reference

clock based on the packets received. Audio can be transmitted from the PM to a PS. The device receiving the

audio is called an Audio Sink, the device sending the audio is called an Audio Source. A device can be both

Audio Sink and Audio Source at the same time (bidirectional audio will be supported in future revisions of the

firmware). The CC8520 network also includes a Data Side-Channel which is a bi-directional data link between

the PM and all PS in the network. This is further described in chapter 8.

Figure 3 illustrates the different network topologies that can be formed with CC8520 using the different

firmware versions.

SWRS091A – MARCH 2010

COEXISTENCE AND AUDIO COMPRESSION

The CC8520 implements a wide range of techniques to maximize coexistence performance when operating in

an environment with other 2.4 GHz wireless devices. The built-in protocol implements adaptive frequency

hopping. This helps improve coexistence with RF sources that do not move around in frequency, such as IEEE

802.11 (Wireless LAN) devices, as well as providing robust performance in a multipath RF environment. Audio

is buffered in the receiver, and any data which is not correctly received, is retransmitted utilizing the high raw

datarate (5Mbps). When link quality is poor (e.g. when moving out of range), audio is muted until a reliable link

is restored.

Forward Error Correction (FEC) is built into the CC8520 modulation scheme. Furthermore, packets are divided

into independent sections so that an error in one section does not mean the whole packet is lost.

The CC8520 supports uncompressed PCM16 audio, with no modifications made to the digital audio. High

quality audio compression can optionally be enabled and effectively reducing average current consumption by

lowering the radio duty-cycle. Compression improves robustness further, as there is less data sent and more

time available for retransmission.

AUDIO INTERFACE

The CC8520 audio interface is I2S compatible and it supports up to 2 audio channels. The audio interface on

the protocol master can be configured as clock master (supplied from the internal audio PLL) or as clock slave

(clock supplied from external audio IC).

The audio interface has 2 data pins. Each of these can be configured as an input, output or unused. The audio

interface can be configured to support I2S. The CC8520 supports word widths of 16 to 24 bits, but over-the-air

16 bits is always used.

HUMAN INTERACTION DRIVERS (HID)

The CC8520 supports basic HID functionality without an external MCU. This means that some basic

functionality can be controlled on the slave remotely from the master. The HID functionality supported

includes:

power control (to turn devices on/off)

network binding (to pair devices)

volume control (volume control can be managed locally)

Status LED (blinking diode to indicate the status of the RF link)

All HID functions are configurable in the PPW Configurator [1] and can be mapped to the CC8520 I/O pins.

EXTERNAL HOST INTERFACE (EHIF / Data side channel)

The external host interface (EHIF) allows an external host device, e.g. a microcontroller, to:

•

Control the operation of and poll status from the CC8520, mainly by taking over driver functionality.

Communicate with other external host devices through an integrated data side-channel

Get access to test functionality for audio, I/O and RF.

The external host interface is available via SPI with a single interrupt pin. The external host will act as SPI

master and CC8520 will act as SPI slave.

User specified data can be transferred between the master EHIF and the slave EHIFs, in both directions using

the data side-channel. The data side-channel establishes robust, ensured-delivery connections in both

directions from any slave to the master or from master to any slave (direct slave to slave communication is not

CC8520

WWW.TI.COM

SWRS091A – MARCH 2010

available). There is no specified minimum throughput for the data side-channel but under normal operating

conditions and data rate of up to 30 kbps is possible in each direction.

More details can be found in the CC8520 User’s Guide [2].

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably

be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing

such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and

acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are

designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated

products in automotive applications, TI will not be responsible for any failure to meet such requirements.
