8.1 Overview

The TS3USBCA4 is a passive 4:1 (TS3USBCA420) and 3:1 (TS3USBCA410) MUX. It supports differential or single-ended signals on the SBU1/SBU2 terminals of a USB Type-C connected to different interfaces. The signals can be 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 (RON), low crosstalk and excellent total harmonic 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 supports operation from a wide VCC range between 2.4 V and 5.5 V, which gives the system designer the flexibility of powering the device from various sources, such as a regulator, a single-cell battery, or VBUS. The TS3USBCA4 provides options for both commercial and industrial temperature ranges.
