USB1101
USB 2.0 FS Peripheral Transceiver (Preliminary)
General Description
The USB1101 provides a USB FS Transceiver functionality
with voltage level translation that is compliant to USB Specification Rev 2.0. The device allows interfacing of USB
Application specific devices with supply voltages ranging
from 1.65V to 3.6V with the physical layer of Universal
Serial Bus. It is capable of operating at 12Mbits/s (full
speed) data rates and hence is fully compliant to USB
Specification Rev 2.0. It supports the DAT_VP/SE0_VM
interface on the host side but offers reduced pin cou nt and
package size. The USB1101 has host side supply rail for
1.65V to 3.6V.
Features
■ Complies with USB Specification Rev 2.0
■ Supports DAT_VP/SE0_VM host mode
■ Utilizes digital inputs and outputs to transmit and receive
USB cable data
■ Supports full speed (12Mbits/s) data rates
■ Ideal for portable electronic devices

Functional Description
The USB1101 transceiver is designed as an Upstream facing port device to convert CMOS d ata into US B differen tial
bus signal levels and to co nve rt USB differe ntial b us si gn al
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 controlled 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 minimize 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 selection 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 configu rations only but interfaces to mixed
voltage supply applications.
