USB Type-C Crosspoint Switch

ANX7408 is an intelligent crosspoint switch that supports switching at data rates of up to 6.75Gbps. ANX7408 supports high-speed interfaces, such as USB 3.1 (Gen 1 – 5Gbps). ANX7408 is designed as a companion IC to various CPUs and Application Processors (APs) to enable notebook PCs, tablets, and smartphones to use mobile connectors such as the reversible USB Type-C (USB-CTM). An On-chip Microcontroller (OCM) is available to manage the signal switching, Channel Configuration (CC) detection, USB Power Delivery (USB-PD) charging and Vendor Defined Message (VDM) protocol, and other functions as defined in the USB Type-C v1.1 and USB Power Delivery v2.0 specifications. ANX7408 can be configured for a Downstream Facing Port (DFP), Upstream Facing Port (UFP), or Dual-Role Port (DRP) to support a USB-C receptacle
