CC8520_1 Datasheet, PDF (2/19 Pages) Texas Instruments – 2.4 GHz RF SoC FOR WIRELESS DIGITAL AUDIO STREAMING CC8520 - PurePath™ Wireless

WWW.TI.COM
DESCRIPTION
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).
