Looking to help companies differentiate their products in an increasingly competitive consumer market, Wolfson Microelectronics has launched the WM5110, said to be the first quad core high definition (hd) audio processor System on a Chip (SoC). The device, which is accompanied by an advanced dsp feature set, is designed to deliver hd audio performance in a range of products, including smartphones and tablet computers.
Duncan Macadie, Wolfson's audio hubs product line manager, said: "Handheld product oems are facing an ever increasing struggle to differentiate their products; the challenge of enabling their products to handle more and more audio demanding use cases, whilst managing growing cost pressures and time to market expectations, is enormous. Consumers expect exceptional quality voice calls, conferencing, audio playback and capture, as well as extended battery life." The WM5110's four dsp cores provide 600MIPS, while the device has a signal to noise ratio of 110dB. Importantly, says the company, it requires driving headphones from the d/a converter requires only 3mW. It also features ambient noise cancellation, acoustic echo cancellation and transmit and receive path noise reduction. Together, these features reduce background noise by up to 90%. "The WM5110 provides ten times the processing capability of our previous generation of products," McAdie noted. "It caters for the needs of both oems and consumers, providing the best hd audio performance on the market today and enables the clear differentiation that oems need to stand out in the global marketplace at a competitive cost.
