Dialog Semiconductor Manages Audio and Power in First Intel-Processor-Based Handset
Posted on: Wednesday, 6 July 2005, 06:00 CDT
Dialog Semiconductor Plc (Nasdaq:DLGS)(FWB:DLG) has announced that a combined audio and power management IC launched by the company last year is featured in a new mobile phone handset claimed to be the first on the market based on an Intel cellular processor. The handset, launched to consumers by mobile network operator O2, uses Dialog's DA9011 GSM/GPRS audio and power controller to provide all the necessary power management and high performance audio functions for the advanced multimedia phone.
Roland Pudelko, CEO & president of Dialog Semiconductor, said, "The new phone features the ability to download music direct to a music player, run several different applications at the same time, provide video and audio playback, and provide up to 200 hours standby and four hours talk time. This is exactly the kind of consumer device that our technology addresses. The DA9011 is helping to manage this significant demand on the battery using our specialist mixed signal design expertise, and it utilizes our advanced knowledge of integrating in the same device high performance audio DACs for CD-quality music and audio playback."
The DA9011 was developed in collaboration with Intel Corporation to support the Intel(R) PXA800F cellular processor. Connecting directly to the battery, the DA9011 provides stable, low noise power supplies for all core circuits within the phone handset, with additional regulators for enhanced application capabilities such as Bluetooth(TM) modules, camera modules, and memory cards. It incorporates Dialog Semiconductor's unique Smart Mirror(TM) technology, a technique which uses advanced compensation and biasing techniques compared to conventional regulators to help minimize quiescent current consumption and optimize power supply rejection (PSRR) performance.
