Sonix
SN11112 is an USB audio controller. It supports
32KHz (which needs driver or application
software support), 44.1KHz or 48KHz sampling
rate in digital recording; 48KHz
sampling in analog recording; and 48KHz in digital/analog
audio playback. In digital playback
mode, it receives audio stream form PC via USB
interface and transmits audio data
according to the AES/EBU, IEC60958, S/PDIF consumer
interface standards. In analog
playback mode, it supports AC 97 Codec for analog
playback.
In
digital recording mode, it receives S/PDIF digital
audio input and sends back to PC through
USB. Three sampling rates; includes 32KHz, 44.1KHz
and 48KHz; are automatically locked internally.
In analog recording mode, fixed 48KHz sampling
rate is supported by analog audio recording.
Totally one control pipe,
two isochronous pipes, and one interrupt pipe
are supported by SN11112.
