Passive and Redriver Models

There are two available models of the USB-C-Switch: Passive and Redriver. The two models have different hardware installed by Acroname during manufacturing; the model cannot be changed after delivery. Acroname places a label on the side of each USB-C-Switch indicating both the model and hardware revision. High-level summary and intended applications of the two models are below with detailed differences in the specification tables.

To get up to speed with the USB-C-Switch and quickly learn about its functionality follow the quick start guide. Have a look at the basic example or dive into the programming interface of the USB-C-Switch for a more in depth view into the capabilities of each model.

Overview

The USB-C-Switch is a platform to simplify switching of multiple USB Type-C ports. The switch is a bidirectional four-to-one or one-to-four multiplexer (mux) which can create a dedicated connection between a device on the common port and a device on one of the available mux channels. The USB-C-Switch gives engineers advanced control of USB connections in testing and development applications. The USB-C-Switch consists of several layers of internal switches to achieve the 4:1 selector and USB line control functionality.

Without any hub or other directional intermediary devices, the USB-C-Switch can behave “like a cable” to connected devices. USB2, USB3, power, CC, Vconn, and SBU, are passed through the USB-C-Switch between the common-port and the selected mux port. Data link, power negotiations and power between USB devices are provided by the attached devices themselves, allowing the USB-C-Switch to be used bidirectionally in either a 1:4 or 4:1 configuration.
