support sample frequencies up to 192kHz. As well as analogue channels the main
board also has MIDI input and output connectors and a COAX connector for S/PDIF
output.
In addition the main board also includes two LEDs, two buttons and one two-
position switch for use by the user application.

2.4 U16 Multi-Channel USB Audio Kit

It is not recommended to use this hardware as a basic for a new design
The XMOS U16 Multi-Channel USB Audio kit
available from XMOS based on a dual tile XMOS U-series device.
The separate USB slice board allows flexibility in the connection method to the USB
audio source/sink as well as other functionality such as 3rd party authentication
ICs and any required USB switching. This also means the XMOS device can be used
as a USB device or host using the same main board.
This document addresses the combination of the main board with the USB AB
slice (part numbers XP-SKC-U16 and XA-SK-USB-AB respectively). This provides a
standard USB Audio device hardware configuration using the B socket on the USB
AB slice.
The core board includes a U-Series device with integrated USB PHY and required
supporting componentry.
Please note, for correct operation the following core-board jumper settings are
required:
J14 (DIA/ALT) should be set to ALT
J15 (D12 XOVER) should be set to ON
The double-slot audio slice (XA-SK-AUDIO8) includes separate multi-channel DAC
and ADC providing 8 channels of both analogue output and input. Both DAC and
ADC devices support sample frequencies up to 192kHz with the DAC supporting
Direct Stream Digital (DSD).
As well as analogue channels the audio-slice also has MIDI input and output
connectors and both COAX and optical connectors for digital output.
Additionally the slice also includes an LED matrix and three push-buttons for use
by the user application.
