Texas Instruments Inc. (TI) and Aliph, a developer of audio and speech technologies and products, have announced that Aliph is leveraging TI's S320C5405 DSP and high-performance analog technology to power Aliph's latest Jawbone headset for mobile phones.

Jawbone uses TI's C5405 device to process multiple audio channels, performing signal identification, adaptive noise subtraction, adaptive audio enhancement, echo cancellation and a variety of other real-time tasks to effectively filter out and transmit only clear voice from within a noisy environment.

In addition to the C5405 device, the Jawbone headset includes several TI analog components designed to increase power efficiency and performance, including four power management products. TI's TPS76927 low-dropout (LDO) voltage regulators provide ultra-low quiescent current and low-dropout voltage in a small SOT-23 package. In addition, Jawbone leverages the TPS6220x 300mA dc/dcC step-down converter, which can achieve up to 95 percent power efficiency and extend battery life.
