Product Summary

The USB1T11ABQX is an one chip generic USB transceiver. The USB1T11ABQX is designed to allow 5.0V or 3.3V programmable and standard logic to interface with the physical layer of the Universal Serial Bus. The USB1T11ABQX 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 USB1T11ABQX conform with the “Serial Interface Engine”. Implementation of the Serial Interface Engine along with the USB1T11ABQX allows the designer to make USB compatible devices with off-theshelf logic and easily modify and update the application.
