High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

This design package includes reference materials for creating a USB - PS/2 combination mouse that auto-detects the interface and configures itself to operate on the appropriate bus.-This design package includes reference materials for creating a USB- PS/2 combination mouse that auto-detects the interface and configures itself to operate on the appropriate bus.
