FAIRCHILD USB1T1105AMHX

Revised August 2005
USB1T1105A
Universal Serial Bus Peripheral Transceiver
with Voltage Regulator
General Description
The USB1T1105A is an Universal Serial Bus Specification Rev
2.0 compliant transceiver. The device provides an USB interface for Full-Speed (12Mbit/s) USB applications. The
USB1T1105A provides excellent flexibility, allowing differential
and single ended inputs while an integrated voltage regulator
sets the I/O level to 1.65V to 3.6V. Utilizing an integrated 5.0V to
3.3V voltage regulator, the part can be powered directly from
the USB host (VBUS) to minimize the power consumed from the
local sources while used in devices with low supply voltages.
The USB1T1105A provides 15kV ESD protection on the USB
bus pins (D/D). This eliminates the need for any external ESD
devices while providing excellent protection to larger and more
expensive ASICs and USB controllers.

output level is relative to VCCIO). Driven LOW when SUSPN is HIGH;
RCV output is stable and preserved during SE0 condition.

active (HIGH) it will drive the RCV pin to logic “0” state.

MODE input (CMOS level is relative to VCCIO). A HIGH selects the differential input
MODE (Vpo, Vmo) whereas a LOW enables the single-ended MODE (Vo, VFSEO) see
Table 2 and Table 3

Functional Description
The USB1T1105A transceiver is designed to convert CMOS
data into USB differential bus signal levels and to convert USB
differential bus signal to CMOS data.
Table 1 describes the specific pin functionality selection. Table
2, Table 3, and Table 4 describe the specific Truth Tables for
Driver and Receiver operating functions.
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. The rise, fall times are balanced between the differential pins to minimize skew.
The USB1T1105A also has the capability of various power supply configurations to support mixed voltage supply applications
(see Table 5) and Power Supply Configurations and Options for
detailed descriptions.

Power Supply Configurations and Options
3-STATE and the USB1T1105A 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
VCCIO such that device is in low power (suspended) state.
Terminals Vbusmon and RCV are forced LOW as an indication of this mode with Vbusmon being ignored during this
state.
The three modes of power supply operation are:
• Normal Mode: Regulated Output and Regulator Bypass
1. Regulated Output: VCCIO is connected and VCC (5.0) is
connected to 5V (4.0V to 5.5V) and the internal voltage
regulator then produces 3.3V for the USB connections.
2. Internal Regulator Bypass Mode: VCCIO is connected and
both VCC(5.5) and VREG(3.3) are connected to a 3.3V
source (3.0V to 3.6V).
• Disable Mode: VCCIO is not connected. VCC is connected, or
VCC and VREG are connected. 0V to 3.3V in this mode D and
D are 3-STATE and VPU is HIGH Impedance (switch is
turned off). The USB1T1105A allows external signals up to
3.6V to share the D and D bus lines. Internally the circuitry
limits leakage from D and D terminals (maximum 10P A).
In both cases for normal mode the VCCIO is an independent
voltage source (1.65V to 3.6V) that is a function of the external circuit configuration.
• Sharing Mode: VCCIO is only supply connected. VCC and
VREG are not connected. In this mode the D and D pins are
