Quad core SoC delivers HD audio for smartphones and tablets

May 25, 2012 // By Paul Buckley
Wolfson Microelectronics has introduced the WM5110, the first quad core high definition (HD) audio processor System-on-a-Chip (SoC).

The highly-integrated, low power HD audio processor with advanced DSP feature set is designed to deliver revolutionary HD audio performance for smartphones, tablet computers and portable multimedia devices, setting a new standard for mobile audio processing.

The WM5110 provides a 110 dB signal-to-noise ratio (SNR) and a fast 600 MIPS of processing power, while only requiring 3 mW DAC to headphone power consumption, making it the most powerful and efficient HD audio processor on the market. Coming complete with its own software development kit, and with enough MIPS and memory to run Wolfson's suite of sound enhancing and noise reduction software, customers' own software or third party software, OEMs can easily create a unique audio signature that will help differentiate their product in the marketplace, delivering a truly platform agnostic and future-proof system.

The WM5110 also features class-leading earpiece and stereo headphone Ambient Noise Cancellation (ANC), Acoustic Echo Cancellation (AEC), and both transmit-path (Tx) and receive-path (Rx) noise reduction, resulting in 32 dB and 20 dB noise reduction respectively. These features combine to provide a reduction in background noise of up to 90%, and a dramatically improved user experience for both the caller and listener.

Combined with additional features including wideband voice, multi-microphone beamforming, wind-noise suppression and other programmable filters, the WM5110 delivers clear and crisp voice calls, even in the noisiest environments; a true multimedia sound experience; outstanding audio capture and playback; and rich and natural-sounding conference calls.

This complete, low cost solution also features 10 fewer components than competitor parts with a comparable solution while providing additional functionality, a smaller PCB footprint and a reduced bill of materials cost for the manufacturer.

The WM5110 is available for limited sampling now in a W-CSP package.
