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 (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 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.
