CC8520 - TI delivers CD-quality wireless audio with new PurePath Wireless family
/ contains 3x video / Texas Instruments (TI) introduced the first device in the family of PurePathWireless audio products for consumer, portable and high-end audio applications, such as wireless headphones and wireless speakers. The CC8520 is an audio transceiver featuring a 2.4-GHz system-on-chip that transmits uncompressed CD-quality wireless audio over a state-of-the-art RF (radio frequency) link with no unwanted noise or dropouts.
The CC8520 simplifies implementation of wireless audio while reducing the
customer’s bill of materials (BOM) cost by 50 percent compared to competitive
products.

“TI has applied extensive design expertise in both digital audio and low-power
RF, working closely with key customers, to deliver a turnkey wireless audio
solution that many major audio customers are already designing into their new
systems,” said Laurent Giai-Miniet, general manager of TI’s Low-Power RF
business unit. “The CC8520 solution includes best-in-class hardware, software
and development kits to streamline the process of eliminating cables in audio
designs and to drive high-performance wireless digital audio into more consumer
applications, such as headphones, headsets, speakers, subwoofers and home
theater systems.”
