USB-C crosspoint switch with re-timer for USB 3.1 (10G) and DP (8.1G)

ANX7441 is a crosspoint switch capable of supporting USB 3.1 Gen-2 (up to 10G), DisplayPort™ Alt Mode (up to 8.1G) and  concurrent USB3.1 (up to 10G), and DisplayPort Alt Mode (8.1G) over a single USB Type-C™ (USB-C) port. ANX7441 has  protocol aware built-in re-timers to recover both the USB or DisplayPort (DP) signals with insertion loss compensation of up  to 23dB. ANX7441 is supported by a digital switch to ensure the enhanced signals from the re-timer are preserved and  outputted over the USB-C connector. Also, ANX7441 integrates the SBU/AUX mux for switching DP AUX signals and  reducing overall system BOM cost.

USB-C Port Controller with Power Delivery
USB Power Delivery PHY with Channel Configuration Control

ANX7401 is a USB Power Delivery (USB-PD) PHY with an On-chip Microcontroller (OCM). The OCM enables ANX7401 to manage the signal switching, Channel Configuration (CC) detection, USB Power Delivery 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. ANX7401 is designed as a companion IC to various CPUs and Application Processors (APs) to enable notebook PCs, tablets, and smartphones to use the reversible USB Type-C (USB-C™) receptacle as a Downstream Facing Port (DFP). In the DFP configuration, ANX7401 has HPD output to support DisplayPort™ Alternate Mode as defined by VESA®.

Main Features: 
Other key features
  • On-chip Microcontroller (OCM) to implement USB- PD messaging and DisplayPort related functions
  • DisplayPort Alternate Mode communication support through USB-PD structured VDM messaging
  • 5V-tolerant CC/VCONN signals
