I. Description
HE11113 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 `HE11113.
