The USB1T11A is a one-chip, generic USB transceiver. It is designed to allow 5.0V or 3.3V programmable and standard logic to interface with the physical layer of the Universal Serial Bus. It is capable of transmitting and receiving serial data at both full-speed (12Mbit/s) and low-speed (1.5Mbit/s) data rates. The input and output signals of the USB1T11A conform with the "Serial Interface Engine". Implementation of the serial interface engine allows designers to make USB-compatible devices with off-the-shelf logic to modify and update the application.
