PDIUSBP11 Datasheet, PDF (2/10 Pages) NXP Semiconductors – Universal Serial Bus transceiver

Philips Semiconductors
Universal Serial Bus transceiver
Preliminary specification
PDIUSBP11
FEATURES
• Utilizes digital inputs and outputs to transmit and receive USB
cable data
• Supports 12Mbit/s “Full Speed” and 1.5Mbit/s “Low Speed” serial
data transmission
• Compatible with the VHDL “Serial Interface Engine” from USB
developer’s conference
• Available in SO, 14 pin package
• Hysteresis on D+, D–, V_MO inputs
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.

NAME AND FUNCTION
Receive data. CMOS level output for
USB differential input
Output Enable. Active LOW, enables
the transceiver to transmit data on
the bus. When not active the
transceiver is in receive mode
Inputs to differential driver. (Outputs
from SIE).

Gated version of D– and D+. Outputs
are logic “0” and logic “1”. Used to

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 suspnd pin is active it will drive
the RCV pin to a logic “0” state.
Edge rate control. Logic “1” operates
at edge rates for “full speed”. Logic
“0” operates edge rates for “low
speed”.
