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.
