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 allows designers to make USB-

compatible devices with off-the-shelf logic to modify and

update the application.

Receive Data. CMOS level output for USB differential input.

/OE I

Output Enable. Active LOW , enables the transceiver to transmit data on the bus.

When not active, the transceiver is in receive mode.

Mode I

Mode. When left unconnected, a weak pull-up transistor pulls it to VCC and, in this

GND, the VMO/FSEO pin takes the function of FSEO (force SEO).

Suspend. Enables a low-power state while the USB bus is inactive. While the

suspend pin is active, it drives the RCV pin to a logic “0” state. Both D+ and D- are 3-

Speed I

Edge Rate Control. Logic “1” operates at edge rates for “full speed.” Logic “0”

operates edge rates for “low speed.”

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device

reliability. The absolute maximum ratings are stress ratings only.
