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.
"TI's C5405 DSP offers the perfect combination of onboard peripherals and memory, a small package size and a 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 analogue components designed to increase power efficiency and performance, including four power management products.
TI's TPS76927 low-dropout (LDO) voltage regulators provide ultralow quiescent current and low-dropout voltage in a small SOT-23 package.
In addition, Jawbone leverages the TPS6220x 300mA DC/DC step-down convertor, which can achieve up to 95% 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 analogue 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 16bit, fixed point DSP that delivers the lowest standby power for its performance class (70-100MMACs) and is the industry's first device available in a 7 x 7mm 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 from www.jawbone.com.
