I. Description
SONiX
SN11113 is an USB audio controller. It supports 32KHz, 44.1KHz and
48KHz sampling rate in digital playback and recording; 44.1KHz and 48 KHz
sampling rate in analog audio playback and recording.
In digital playback mode, it receives audio stream from 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 32 KHz, 44.1 KHz, and 48 KHz; are
automatically locked internally. In analog recording mode, 44.1KHz and 48 KHz
sampling rate are supported by analog audio recording.
Totally one control pipe, two isochronous pipes, and one interrupt pipe are supported
by SN11113.
