Data Sheet USB Two Channel Audio Controller SN11113 DATA SHEET SN11113 USB Two Channel Audio Controller Revision 1.1 Copyright © 2003, Sonix Technology Co., Ltd. All rights reserved. Data Sheet USB Two Channel Audio Controller SN11113 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. II.
