USB multicore microcontrollers from Xmos have been selected by Sony for its new PHA-2 portable headphone amplifier.
The company’s xCORE-USB multicore microcontrollers will be used in the design of the Sony PHA-2. This device uses multiple audiophile USB interfaces with a high resolution DAC and headphone amp and is compatible with USB Audio Class 2 and DSD (Direct Stream Digital) technology; as a result this is said to provide a higher quality audio experience for listeners.
The headphones can support music files with sample rates of up to 192kHz and full 24-bit resolution, that is said to be on par with studio quality digital audio.
With the rising demand for higher quality music from portable devices, this range of microcontrollers is well equipped to meet these demands. They can be programmed to support a wide variety of streaming formats, including asynchronous data transfer that ensures jitter is removed. In addition to this, XMOS advises its solutions support a range of source devices including PCs, portable music players, current and legacy Apple products, and common Android smartphones.
