XMOS USB Audio 2.0 Reference Design
XMOS introduced a reference design for USB Audio 2.0. The solution enables standard computer-based systems to deliver bit-perfect prosumer quality sound. The reference design works with the Mac OS-X 10.6 (Snow Leopard) Audio 2.0 native class driver, and XMOS has teamed with Thesycon to provide Audio 2.0 Class driver support for Windows. The XMOS USB Audio 2.0 reference design kit is available now and priced at $149 USD.
Implemented entirely in software, using the XMOS XS1-L1 event driven processor, the design supports hi-speed USB Audio 2.0 connectivity and up to 6 input and 6 output audio channels at 24-bit resolution and a sample rate of 192 kHz. Higher audio channel counts are also supported using the XMOS L2 and G4 devices.
A key factor in the reproduction of high quality audio, the reference design’s unique asynchronous clocking mode achieves sub-3ms roundtrip latency, making it suitable for live music playback. The credit card sized reference design board will suit the development of speakers, home theatre systems, sound cards, musical instruments and professional audio equipment.
The reference design’s software-defined workflow also enables users to readily adapt and customize the solution to handle specific interfacing requirements, DSP algorithms for audio enhancements and custom ‘front-of-box’ peripherals. To reduce development time, XMOS’ ready-made library of software components already includes I2S, S/PDIF and many other interfaces.
