Oct 25, 2004

HOUSTON and BRISBANE, CA (October 25, 2004) – Strengthening its commitment to design technology that promotes customer innovation, Texas Instruments Incorporated (NYSE: TXN) (TI) and Aliph, a developer of next-generation audio and speech technologies and products, today announced that Aliph is leveraging TI's TMS320C5405™ digital signal processor (DSP) and high-performance analog technology to power Aliph's new Jawbone™ headset for mobile phones. For more information see www.jawbone.com.

Jawbone, a cutting-edge product for mobile phone headsets, provides a superior level of audio performance allowing users to communicate more clearly in almost any noisy environment. As mobile phone usage continues to proliferate, consumers are demanding that the performance, comfort and style be augmented as well. TI´s C5405 gives Jawbone all the processing power it needs to combat noise in an aesthetically pleasing consumer device.

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. The smaller size, low power consumption and extended functionality enabled by the DSP allowed Aliph designers to build a headset with unmatched performance in a package compact enough to surpass consumer expectations. For more information on the C5405 DSP, please see www.ti.com/c5405p.

"TI's C5405 DSP offers the perfect combination of on-board peripherals and memory, a small package size and a very good price/performance ratio for our Jawbone headset," said Ira Gerson, vice president, technology, Aliph. "We selected TI's DSP because it allowed us to meet our goal of delivering a superior customer experience in an innovative, wearable design."

In addition to the C5405 device, the Jawbone headset includes several TI high-performance 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 300-mA DC/DC step-down converter, which can achieve up to 95 percent power efficiency and extend battery life.

"We are delighted that Aliph and other small-scale end equipment developers can now better leverage the power of real-time processing while reducing device footprint by two thirds," says Raj Agrawala, C5405 product marketing manager, TI. "Aliph´s Jawbone is the perfect example of our customers using both TI DSP and high-performance analog technology to push the innovative envelope and deliver technology that helps them win in their markets."

Space is at a premium in a sleek mobile application such as Jawbone. TI´s C5405 is the only DSP that, in one package, meets and surpasses the size, power and functionality such consumer products demand. The new TMS320C5405 is a 16-bit, fixed point DSP that delivers the lowest standby power for its performance class (70-100 MMACs) and is the industry´s first device available in a 7 mm x 7 mm package. TI´s C5405 DSP is sampling now, with volume production scheduled for the fourth quarter of 2004. Planned pricing is $5.20 per unit in quantities of 10,000 units. Jawbone is exclusively available through the website www.jawbone.com, or by calling 1-866-JAWBONE.
