3 Description

The TS3USB3031 device is a 2-channel, 1:3

multiplexer that includes a high-speed Mobile High-

Definition Link (MHL), Mobility Display Port (MyDP)

switch, and USB 2.0 High-Speed (480Mbps) switches

in the same package. These configurations allow the

system designer to save board space and eliminate

multiple connectors buy using a common USB or

Mico-USB connector for MHL/MyDP signals and two

sets of USB data. The MHL/MyDP path supports the

latest MHL Rev. 3.0 specification.

The TS3USB3031 has a VCC range of 2.5V to 4.3V

and supports overvoltage tolerance (OVT) feature,

which allows the I/O pins to withstand overvoltage

conditions (up to 5.5V). The power-off protection

feature forces all I/O pins to be in high impedance

mode when power is not present, allowing full

isolation of the signals lines under such condition

without excessive leakage current. The select pins

of TS3USB3031 are compatible with 1.8V control

voltage, allowing them to be directly interfaced with

the General Purpose I/O (GPIO) from a mobile

processor with out needing additional voltage level

shifting circuitry.

The TS3USB3031 is available in a small 1.8mm ×

1.8mm 12-pin VQFN package designed for mobile

applications.
