GL811E

Product Summary

The GL811E is a highly-compatible, low cost USB 2.0 to ATA / ATAPI bridge controller, which integrates Genesys Logic own design high speed UTMI (USB 2.0 Transceiver Macrocell Interface) transceiver. The GL811E uses 12MHz crystal and slew-rate controlled pads to reduce the EMI issue. With 48-pin LQFP (9mmX9mm) package, the GL811E is the best cost/ performance solution to fit different situations in the USB 2.0 high speed storage class applications such as Hard Disk, CD-ROM, CD-R / RW and DVD-ROM.
