XMOS based, USB2 audio card, low power consumption, small form factor, 8 synchronous input channels and 4 stereo output channels.

Features

  • Connectivity USB Type B - Powered by computer via the USB port
  • 5V External power supply (REV3)
  • Automatic switching power supply - USB or external 5V power supply, priority on external power supply
  • USB 2.0 compatibility - High-Speed devices 480Mb/s compatible via a USB Hub powered
  • Drivers - Mac, Windows and Linux, acquiring multi-channel audio with version 2.0 of USB Audio Class. Automatic driver installation by the exploitation system. Third-party driver needed for Windows.
  • 8 synchronized analog differential inputs - RJ11 input format, all managed as individual channels, 100kΩ load impedance, providing 4.3 volts for microphones
  • 2 Analog stereo outputs - 3.5 mm jack output format, 10 kΩ source impedance
  • XMOS XS1-L16A-128-QF124 Processor MIPS 800/1000, 16 threads, speed depend on speed grade (C8,C10)
  • Support for standard sampling frequencies - 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz
  • Bit stream audio data - 8 inputs and 4 outputs up to 24-bits 192 kHz, ENOB 22-bits
  • XSYS2 connectivity - To program the processor using the debug adapter XMOS XTAG2
  • Connectivity expansion XMOS - With I/O to add an L-type Core XMOS only for future design
  • Noise signals to the acquisition - 0.1% THD, noise Floor medium -132dBv and -112dBv maximum
  • Test points - Multiple connections test points ADC/DAC, power supply, etc.
  • Based on XMOS USB AUDIO 2.0 MC Reference Design
