PI5USB31213AXEADemo Board Rev.B User Manual
◆Introduction
◆PI5USB31213A is a dual differential channel bi-directional Mux/Demux switch with plug-in detector for USB 3.1 Type-C connector applications.
◆PI5USB31213A is designed for USB 3.1 Gen2 (10 Gbps) application.
◆The device includes:
●The Plug-in Detector for Type-C connector (CC Sensing)
▲Supports Source/Sink/DRP/Try.SRC DRP/Try.SNK DRP
●Integrated 2:1 USB3.0 Mux/DeMux
▲Auto-configure ports orientation through CC Sensing
●Integrated VCONN switch to power active cable
■PI5USB31213A detects the plug-in orientation of the cable at a Type-C connector and switches between the USB controller and the new Type-C connector. It supports Host (Source/DFP) mode, Device (Sink/UFP) mode, Dual Role Port(DRP), Try.SRC DRP and Try.SNK DRP with automatic configuration based on the voltage levels detected on CC pins.It offers excellent signal integrity for high-speed signals at low power dissipation. PI5USB31213A enters disabled state when ENB pin is pulled up to VDD through an internal resistor.
■PI5USB31213A supports both pin and I2C control base on ADDR pin setting. It allows the system choose between pin control and I2C control mode. In pin control mode, the PORT input pin determines the port setting in which Source(DFP) only mode,Sink(UFP) only mode or Try.SNK DRP can be selected. Enabling I2C control mode allows higher flexibility for port control and communications through registers read/write in PI5USB31213A. There is also flexibility to support Default, 1.5A and 3A current modes. An interrupt signal for indicating changes with the I2C registers is sent to the master to notify the system any change in the Type-C connector while in parallel the system can still monitor ID pin.
