austriamicrosystems has announced that Core Logic, a provider of integrated application processor chipsets and newer chipsets for portable navigation devices (PNDs) under the brand name JADE, has selected its AS3518 audio codec and advanced power management IC (audio front end) to power a reference design aimed at personal navigation devices and multimedia phones.

AS3518 is a member of a family of integrated audio and power management devices that combine in a monolithic chip all system analog functions required for a digital SoC for mobile entertainment devices. austriamicrosystems targets versatile single-chip companion analog devices that complement increasingly complex mobile SoC processors by still saving board space and cost while offering improved performance when compared to discrete components.

austriamicrosystems' flexible and highly integrated audio and power management devices include functions such as low power and high quality audio DAC and ADCs, audio amplifiers, battery charging for Li-ion and other popular types, efficient DC/DC step-up/step-down power converters, LDOs, ultralow-power RTC, high voltage backlight power unit and touch screen interface amongst others. Advanced power management techniques like dynamic voltage with frequency scaling or adjustable DC/DC converters enable high efficiency over a wide range of current loads. A DC/DC step-down charger with wide-input range and programmability supports high current battery charging.

"The focus on supporting Core Logic in their development of personal navigation applications has enabled austriamicrosystems to deliver reference designs with simplified end customer support and rapid deployment to market of new products," said Roberto Simmarano, senior marketing director communications at austriamicrosystems. "Our customers expect the very best technologies with minimal time-to-market constraints so we are proud to work with a leading provider setting the pace in the Asian market in highly integrated application processors for multimedia phones."
