resistor on D
when HIGH. If device is used as Downstream
port then this pin is hard-wired to GND.
Output Enable (active LOW)

When OE H receive mode (CMOS level is relative to V
CCIO
) is enabled.
When in transmit mode
(Note 2)
DAT_VP is a single-ended host data input
(CMOS level relative to V
CCIO
).
When in receive mode
(Note 1)
and Suspnd L DAT_VP is a single ended
data output comprised of the differential input data from the D
/D
inputs
(see Table 2);
When in receive mode
(Note 1)
with Suspnd H DAT_VP outputs the D
data.
(see Table 1 and Table 2) Output drive is 2mA (min) buffer
When in transmit mode
(Note 2)
SE0_VM is a data input (CMOS level rela-
tive to V
CCIO
).
When in receive mode
(Note 1)
and Suspnd L, SE0_VM is used as an out-
put (see Table 2)
(see Table 1 and Table 2). Output drive is 4ma (min) buffer
GND
Enables a low power state (CMOS level is relative to V
CCIO
).
In receive mode
(Note 1)
with Suspnd L the DAT_VP pin will be a function
of the D
/D
lines.
In receive mode
(Note 1)
with Suspnd H DAT_VP will have the value of D

Functional Description
The USB1101 transceiver is designed as an Upstream fac-
ing port device to convert CMOS data into USB differential
bus signal levels and to convert USB differential bus signal
to CMOS data. If you wish to use these as downstream
devices, Config must be hard-wired to GND.
To minimize EMI and noise the outputs are edge rate con-
trolled with the rise and fall times controlled and defined for
full speed data rates only (12Mbits/s). The rise and fall
times are balanced between the differential pins to mini-
mize skew.
The USB1101 supports the DAT_VP/SE0_VM format from
the OTG Transceiver Specification using the DAT_SE0
Mode. Table 1 describes the specific pin functionality selec-
tion and Table 2 describes the specific Truth Tables for
Driver, Receiver, and Suspended operating functions.
The USB1101 has the capability of serving Self Powered
power supply configurations only but interfaces to mixed
voltage supply applications.

Note 5:
DIFF denotes that the output of the differential receiver is output via DAT_VP when Suspnd L. This output should also not be gated by the SE0 or
SE1 condition when a skew between D
and D
signals could result in the short SE0 or SE1 conditions. Please refer to Expectation Notes for further infor-
mation.
Note 6:
This is the internal single ended output that is output on to DAT_VP when Suspnd
H and in receive mode.
Power Supply Configurations and Options
The modes of power supply operation include:
1. Self Powered Mode: V
CC
is connected to 3.3V source
(3.0V to 3.6V). This external supply connection pro-
vides the 3.3V for the USB pull-up source, the receiver
input and driver output circuitry.
2. Sharing Mode: V
CCIO
is connected and V
CC
is
d
0.8V.
In this mode the D
and D
pins are 3-STATE and the
USB1101 allows external signals up to 3.6V to share
the D
and D
bus lines. Internally the circuitry limits
leakage from D
and D
pins (maximum 10
P
A) and
V
CCIO
such that the device is in low power state.
3. Disable Mode: V
CCIO
is
d
0.5V and V
CC
is connected.
In this mode the D
and D
pins are 3-STATE and the
device is in low power state.
A summary of the Supply Configuration is described in
Table 3.

Note 7:
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 Characteristics table are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
