XMOS XR-USB-AUDIO-2.0-MC

USB Audio 2.0 Multichannel Reference Design

USB Audio Class 2.0 provides a dramatic improvement over USB Audio Class 1.0 with the addition of 24 bit audio, sample frequencies up to 192kHz and the ability to scale to large numbers of input/output channels.,XMOS has developed a USB Audio Class 2.0 software framework design to work on XS1-L devices. The design provides certified USB 2.0 High Speed device and Audio Class 2.0 device class implementations with configurable digital audio interfaces, peripherals and the ability to integrate audio processing.

Dual-core 1000MIPS, 16 threads, XS1-L2 processor
Streams bit perfect audio data up to 24-bit @ 192kHz
Supports standard sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz
USB endpoints use the asynchronous synchronization mode to allow an external low jitter audio master clock to be used
6 channel analogue input, 8 channel analogue output
S/PDIF output and input via RCA or TOSLINK with high quality local PLL for clock recovery
MIDI I/O, Musical instrument/MIC compatible input, House clock input, I/O expansion
XMOS XSYS debug header for easy programming/debug from the host using the XMOS XTAG2 debug adapter
