Sony chooses xCORE multicore microcontroller

08 October 2013

XMOS’ xCORE-USB multicore microcontrollers were selected by Sony for its new PHA-2 portable headphone amplifier.

The Sony PHA-2, launched at IFA last month, combines multiple audiophile USB interfaces with a high resolution DAC and a high-quality headphone amp, all in a tiny portable product. It is compatible with USB Audio Class 2 and DSD (Direct Stream Digital) technology, providing a higher quality audio experience for listeners using the Sony Walkman line of portable music players, Windows and Mac PCs, as well as iPads, iPods, and iPhones.

“The XMOS solution is proven to deliver the highest quality USB audio,” said Nigel Toon, XMOS CEO. “As a programmable platform, xCORE has allowed Sony to equip the PHA-2 with unique features such as Direct Stream Digital. xCORE was also the only platform that could fully meet Sony’s exacting product requirements: We believe users of the PHA-2 will be able to hear the results for themselves.”

The Sony PHA-2 is based on XMOS’ industry-leading USB audio solution, using the xCORE XS1-U8-64 8-core multicore microcontroller. It is capable of supporting music files with sample rates of up to 192kHz and full 24-bit resolution, delivering studio quality digital audio.

People are demanding higher quality music from their portable devices and xCORE multicore microcontrollers deliver this. They can be programmed to support a wide variety of streaming formats, including asynchronous data transfer that ensures jitter is removed. XMOS solutions support a range of source devices including PCs, portable music players, current and legacy Apple products, and common Android smartphones.
