Features:

SN11020 provides a high-performance interface to bridge USB and ATA/ATAPI/SD/MMC compliance device. It provides a flexible and low cost single chip solution for application intened to utilize the convenience of USB. The DMA/Ultra DMA feature in ATA/ATAPI-4 specification is not support since the bootleneck in data transfer between ATA device and USB1.1 host is on the USB side. The maximum supported serial clock in SD/MMC interface is 12MHz and the supported block length is 2048 bytes. The external serial EEPROM gives users the flexibility to customize USB vendor ID and product ID for various version of products. This controller chip could be used to connect IDE hard disk, Compact Flash, MMC or SD memory card. In addition, CD-ROM and CD-RW driver is to be released in the near future. * USB 1.1 compatible. * Support ATA/ATAPI, PIO mode 0. * SD memory card specification 1.0 compatible. * MMC memory card specification 2.1.1 compatible. * SD/MMC serial clock rate is up to 12MHz. * Built-in FIFO for upstream and downstream data transfer. * Pin selectable bus-power or self-power. * Eight user-defined general purpose IO. * Drivers support Microsoft Win 98/Win 2000/Win Me/Mac OS 8.6/Mac OS 9. * Single 3.3V operation in 80-pin FQFP package.

USB 5.1 Channel Audio Controller SN11110

Features:

Sonix SN11110 is an USB audio controller. It supports 32KHz, 44.1KHz (which two need driver or application software support) and 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. Only R, L channel PCM audio in 5.1 channel can be conveyed in digital playback mode. In analog playback mode, it supports 6 channels 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 SN11110.
