NXP Semiconductors has 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.
This solution leverages the 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.
The 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.
