USB Type-C Crosspoint Switch

ANX7418 is an intelligent crosspoint switch that supports switching at data rates of up to 6.75Gbps. ANX7418 supports high-speed interfaces, such as USB 3.1 (Gen 1 – 5Gbps) and DisplayPortTM (DP) 1.3 at up to HBR2.5 (6.75Gbps). ANX7418 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. An integrated microcontroller (MCU) 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 v1.0 and USB Power Delivery v2.0 specifications. ANX7418 can be configured for a Downstream Facing Port (DFP), Upstream Facing Port (UFP), or Dual-Role Port (DRP) to support a USB Type-C receptacle. In the DFP configuration, ANX7418 supports the DisplayPort Alternate Mode as defined by VESA® to carry high-definition audio and video (A/V) contents at 1 or 2-lanes DP over the USB Type-C connector.
