Quad-core HD audio SoC is industry’s first
Claimed to be the first of its kind, the WM5110 quad-core HD audio processor SoC offers an advanced DSP feature set — enabling HD Audio performance for smartphones, tablet computers, and portable multimedia devices and setting a new standard for mobile audio processing. The part provides 110-dB SNR and 600 MIPS of processing power, while only requiring 3-mW DAC-to-headphone power consumption.
It comes 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. The WM5110 also features earpiece and stereo headphone ambient noise cancellation, acoustic echo cancellation, and both transmit-path and receive-path noise reduction, resulting in 32- and 20-dB noise reduction, respectively. All these features enable a reduction in background noise of up to 90% and an improved user experience for both the caller and listener.
It also features wideband voice, multi-microphone beamforming, wind-noise suppression and other programmable filters. Housed in a W-CSP package, the part is also claimed to feature 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.
