USA: NXP Semiconductors (NXP) launched a new solution to drive the standardization of USB 2.0 for portable consumer devices – the world's first USB-driven digital audio headset solution, Nexperia PNX0161.

The new solution from NXP leverages USB 2.0 standard to shift the core audio streaming functions to the USB connector on the host device, alongside the existing battery charging and PC synchronization functions. This feeds the market trend for ultra-thin devices with a simplified design and a single standardized connection interface, enabling a marked reduction in bill-of-material costs and a quicker time to market. According to In-Stat analyst, Brian O'Rourke, "By 2011, hi-speed USB will dominate as the local interface on portable devices, feeding a market of 2.7 billion units at a CAGR of 24.4 percent."

"USB is fast emerging as a de facto connectivity interface in portable devices. NXP is leveraging its pole position to promote the adoption of USB technology with industry-first innovations, setting the stage for the future of USB applications for better connectivity and convenience on mobile phones, consumer electronics and PC peripherals," said Hans Fleurkens, product marketing manager, Mobile & Personal Business Unit, NXP Semiconductors. "Power consumption was the biggest challenge to the provision of digital audio on a headset, and NXP's PNX0161 is the first to address this most efficiently, while also offering a choice of functionality through a programmable core."

NXP's USB-driven digital audio headset solution, Nexperia PNX0161, has built-in DSP software, allowing OEMs to pre-set equalizers and maximize echo cancellation for improved sound quality. The programmable ARM7TDMI core is embedded with a DC/DC converter, which powers through the USB bus. Fully compliant with USB specifications, the solution offers plug-and-play operation with any USB host or On-The-Go (OTG) device and supports USB Audio and Human Interface Device (HID) classes.

In addition, foreseeing the emerging standardization of USB 2.0 in mobile devices, NXP also expands its applications for a compelling GSM/MP3 docking station reference design for maximum functionality such as mobile phone and MP3 player power charging, FM-radio enabled speakers and Bluetooth connection.
