USB1T11A Universal Serial Bus Transceiver
November 1999 Revised March 2005
USB1T11A Universal Serial Bus Transceiver
General Description
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 along with the USB1T11A allows the designer to make USB compatible devices with off-theshelf logic and easily modify and update the application.
Features
s Complies with Universal Serial Bus specification 1.1 s Utilizes digital inputs and outputs to transmit and receive USB cable data s Supports 12Mbit/s "Full Speed" and 1.5Mbit/s "Low Speed" serial data transmission s Compatible with the VHDL "Serial Interface Engine" from USB Implementers' Forum s Supports single-ended data interface s Single 3.3V supply s ESD Performance: Human Body Model ! 9.5 kV on D, D pins only ! 4 kV on all other pins s 16-lead Pb-Free MLP package saves space

Data, Data. Differential data bus conforming to the Universal Serial Bus standard. Suspend. Enables a low power state while the USB bus is inactive. While the suspend pin is active it will drive the RCV pin to a logic "0" state. Both D and D are 3-STATE. Edge rate control. Logic "1" operates at edge rates for "full speed". Logic "0" operates edge rates for "low speed". 3.0V to 3.6V power supply Ground reference

Note 3: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristic tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation.
