MIPS Technologies Strengthens Leadership in Analog/Mixed-Signal IP With Innovative Audio Solution for Multimedia Applications

New Linearized Digital Audio IP Reduces Area by 50% Over Class-A/AB with Same Performance

LISBON, Portugal, Feb. 2 /PRNewswire-FirstCall/ -- MIPS Technologies, Inc. (NASDAQ: MIPS), a leading provider of industry-standard architectures, processors and analog IP for digital consumer, home networking, wireless communications and business applications, today introduced new Linearized Digital Audio IP for multimedia applications. The new Audio IP provides a high-quality, compact line driving solution for a wide range of applications including DVD players, digital photo frames, set-top boxes and iDTVs.

The new Linearized Digital Audio line driver is a significant addition to MIPS Technologies' Audio IP solutions. It replaces the traditional Class A/AB line driver, resulting in an area savings of approximately 50%, while keeping the same Hi-Fi performance. MIPS Technologies achieves this through an innovative technique in linearization of the pulse width modulation (PWM) output signal. The IP can be implemented standalone or as part of an audio subsystem across multiple process technologies in major foundries.

"It is increasingly common to incorporate analog audio functionality onto SoCs, especially for multimedia applications in mobile devices," said Nuno Ramalho, vice president of Audio and Power Solutions, Analog Business Group, MIPS Technologies. "Our new line driver technology is a breakthrough that significantly decreases area while keeping the same quality. To-date, MIPS Technologies is the only company supplying this innovative and valuable solution for next-generation SoCs."

MIPS Technologies' unique family of Class-D Audio and Linearized Audio DACs incorporates a complete, high-quality playback channel optimized for low power consumption and longer battery life for a wide array of consumer devices. High-order, over-sampling sigma delta technology is used together with drivers to achieve high efficiency. The channel filters are implemented digitally, embedded in the decimation and interpolation filters associated with the converters. Individual volume control schemes allow maximum flexibility in combining different playback functions. External component requirements are minimal, as no separate external references are required.
