DESCRIPTION

The PDIUSBP11 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 outputs from

the serial interface engine (inputs VPO and VMO on the

PDIUSBP11) are driven by the host. The gated inputs (outputs VP

and VM on the PDIUSBP11) are to be decoded by the host.

Implementation of the Serial Interface Engine along with the USB

transceiver allow the designer to make flexible USB compatible

devices with widely available logic components.
