3 Description

The TS3USBCA4 is a passive 4:1 (TS3USBCA420)

and 3:1 (TS3USBCA410) MUX supporting various

types of differential or single-ended signals on the

SBU1/SBU2 terminals of a USB Type-C connector to

different interfaces. Those signals can be differential

DisplayPort auxiliary (AUX), analog audio MIC and

AGND, PCIe differential clock, or any other supported

generic differential or single-ended signals.

The audio path features ultra-low ON-state resistance

distortion (THD). The break-before-make feature

prevents signal distortion during signal transfer from

one channel to another. The high-speed paths

support bandwidth as high as 500 MHz to provide

adequate support for DisplayPort AUX, PCIe clock,

and other similar signals. Together with low power

consumption,

these

features

make

this

device

suitable for portable audio applications.

The TS3USBCA4 wide supply range from 2.4 V to

5.5 V gives users the flexibility of powering it from a

single-cell battery, a 3.3-V regulator, or VBUS. It also

provides options for both commercial and industrial

temperature ranges.
