Audio codec achieves 16kHz wideband noise for mobile devices

Keywords:audio codec? DSP? amplifiers?

Texas Instruments Inc. has released an audio codec equipped with two embedded miniDSP cores and five amplifiers. Targeting mobile devices, the codec is said to enable wideband noise and echo cancellation at up to 16kHz.

The codec provides designers with 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 multipurpose and HD audio designs for mobile devices.

The codec provides designers with the ability to interface to up to three devices simultaneously, such as application, Bluetooth and baseband processors.

The codec's third-generation miniDSP technology enables wideband noise and echo cancellation at up to 16kHz to create clear, high-definition voice quality for circuit-switched or VoIP calls, including video conferencing applications.

It features SRS WOW HD to improve audio playback quality and enable 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.

It has three asynchronous audio buses plus asynchronous sampling rate conversion (ASRC) that allows designers to connect to multiple audio sources and mix multiple sample rates.

Also, 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 x 4.8mm WCSP package, priced at $4.95 in quantities of 1,000.
