DESCRIPTION/ORDERING INFORMATION
The TUSB1105 and TUSB1106 universal serial bus (USB) transceivers are compliant with the Universal Serial
Bus Specification Rev. 2.0. These devices can transmit and receive serial data at both full-speed (12-Mbit/s) and
low-speed (1.5-Mbit/s) data rates. The TUSB1105 and TUSB1106 can be used as USB device transceivers or
USB host transceivers.
The devices allow USB application-specific ICs (ASICs) and programmable logic devices (PLDs), with
power-supply voltages from 1.65 V to 3.6 V, to interface with the physical layer (PHY) of the universal serial bus.
They have an integrated 5-V to 3.3-V voltage regulator for direct powering via the USB supply VBUS.
The TUSB1105 allows single-ended and differential input modes selectable by a mode (MODE) input and is
available in RGT and RTZ packages. The TUSB1106 allows only differential input mode and is available in PW,
RGT, RSV, and RTZ packages.
The TUSB1105 and TUSB1106 are ideal for portable electronic devices, such as mobile phones, personal digital
assistants, information appliances, and digital still cameras.

FUNCTION
Signal levels on D+ and D– are determined by other USB devices and external pullup/pulldown resistors.
In suspend mode (SUSPND = HIGH) the differential receiver is inactive and output RCV is always LOW. Out of suspend (K), signaling is
detected via the single-ended receivers VP and VM.
During suspend, the slew-rate control circuit of low-speed operation is disabled. The D+ and D– lines are still driven to their intended
states, without slew-rate control. This is permitted because driving during suspend is used to signal remote wakeup by driving a K signal
(one transition from idle to K state) for a period of 1 ms to 15 ms.

Power-Supply Configurations
The TUSB1105/1106 can be used with different power-supply configurations, which can be dynamically changed.
An overview is given in Table 7.
• Normal mode – Both VCC(I/O) and VCC(5.0) or (VCC(5.0) and Vreg(3.3)) are connected. For 5-V operation, VCC(5.0) is
connected to a 5-V source (4 V to 5.5 V). The internal voltage regulator then produces 3.3 V for the USB
connections. For 3.3-V operation, both VCC(5.0) and Vreg(3.3) are connected to a 3.3-V source (3 V to 3.6 V).
VCC(I/O) is independently connected to a voltage source (1.65 V to 3.6 V), depending on the supply voltage of
the external circuit.
• Disable mode – VCC(I/O) is not connected, VCC(5.0) or (VCC(5.0) and Vreg(3.3)) are connected. In this mode, the
internal circuits of the TUSB1105 and TUSB1106 ensure that the D+ and D– pins are in 3-state and the
power consumption drops to the low-power (suspended) state level. Some hysteresis is built into the
detection of VCC(I/O) lost.
• Sharing mode – VCC(I/O) is connected, (VCC(5.0) and Vreg(3.3)) are not connected. In this mode, the D+ and D–
pins are made 3-state and the TUSB1105 and TUSB1106 allow external signals of up to 3.6 V to share the
D+ and D– lines. The internal circuits of the TUSB1105 and TUSB1106 ensure that virtually no current
(maximum 10 mA) is drawn via the D+ and D– lines. The power consumption through VCC(I/O) drops to the
low-power (suspended) state level. Both the VP and VM pins are driven HIGH to indicate this mode. Pin RCV
is made LOW. Some hysteresis is built into the detection of Vreg(3.3) lost.

Power-Supply Input Options
The TUSB1105 and TUSB1106 have two power-supply input options.
• Internal regulator – VCC(5.0) is connected to 4 V to 5.5 V. The internal regulator is used to supply the internal
circuitry with 3.3 V (nominal). Vreg(3.3) becomes a 3.3-V output reference.
• Regulator bypass – VCC(5.0) and Vreg(3.3) are connected to the same supply. The internal regulator is bypassed
and the internal circuitry is supplied directly from the Vreg(3.3) power supply. The voltage range is
3 V to 3.6 V to comply with the USB specification.
The supply-voltage range for each input option is specified in Table 8.

Peripheral-Side (Full-Speed) Regulator Bypass Mode
This mode is applicable when there is a 3.3-V supply already available on the board. The VBUS pin of the USB
connector, if left unused at the peripheral side, should be terminated with a 0.1-mF capacitor. While operating at
full speed, the 1.5-kΩ resistor must be connected between the D+ line and VPU(3.3) or an external 3.3-V supply.
When the VCC(5.0) and the Vreg(3.3) are connected together, the device operates at regulator bypass mode. This
enables power savings since the regulator is turned off.

Peripheral-Side (Full-Speed) Internal Regulator Mode
The USB side of the TUSB1105/1106 can be powered from the VBUS line directly if a 3.3-V supply is not present
on board. In this case, the internal regulator can be used to provide the 3.3-V supply for USB signaling. The
VCC(5.0) is connected to the VBUS, which receives 5-V supply from the host, and generates the 3.3-V output at the
Vreg(3.3) pin. In this mode, it is important that both VCC(5.0) and Vreg(3.3) pins have individual bypass capacitors in
the range of 0.1 mF. Powering VCC(5.0) through the VBUS port of the USB connector realizes significant power
saving for portable applications, such as cell phones, PDAs, etc. In this operating mode, the ICC(5.0) current is fed
from the host. The USB-side power consumption, ICC(5.0 ) is 4 mA (with the regulator active), as opposed to
logic-side ICC(IO) of 1 mA under full-speed operation. While operating at full speed, the 1.5-kΩ resistor must be
connected between the D+ line and the VPU(3.3) or an external 3.3-V supply.

If there is no 3.3-V supply on board, an external 5-V supply can support the USB-side power needs. When the
VCC(5.0) is connected to an external 5-V supply, the on-chip regulator generates the 3.3-V internal supply rail,
which is used to drive the USB signaling levels at the USB side of the TUSB1105/1106. The logic-side I/Os can
operate at any voltage range from 1.65 V to 3.6 V.
