Audio codec for mobile devices provide echo and noise cancellation at wideband voice sampling rates up to 16-kHz
April 26, 2012 // Paul Buckley
Texas Instruments Incorporated has introduced the industry's most highly integrated audio codec with embedded miniDSP cores, providing echo and noise cancellation at wideband voice sampling rates up to 16 kHz.
The TLV320AIC3262 integrates five amplifiers and two miniDSP cores, and gives designers the ability to interface to up to three devices simultaneously, such as application, Bluetooth and baseband processors. Audio and voice samples can be received, mixed and processed seamlessly within the codec. The inclusion of TI audio and voice algorithms, as well as third party algorithms, available on the codec and as additional licenses, benefits designers creating multi-purpose and high-definition audio designs for mobile devices.
The TLV320AIC3262 uses third-generation miniDSP technology that enables wideband noise and echo cancellation at up to 16 kHz to create clear, high-definition voice quality for circuit-switched or VoIP calls, including video conferencing applications.
SRS WOW HD are included as a standard feature at no additional cost to customers, improves audio playback quality and enables faster processing by offloading the duties of the host processor to the codec. Designers can also evaluate other certified pre-integrated SRS solutions such as TruMedia, CircleSurround Headphone and TruSurround HD , which are available commercially through direct licensing agreements with SRS Labs, Inc.
Three asynchronous audio buses plus asynchronous sampling rate conversion (ASRC) allows designers to connect to multiple audio sources and mix multiple sample rates. The device's Intelligent speaker protection algorithms control voice coil temperature and diaphragm excursion to enable maximum possible loudness without damaging the speaker.
The TLV320AIC3262 is available now in a 4.8-mm x 4.8-mm WCSP package, priced at $4.95 in quantities of 1,000.
