PI3EQX10312 TM 10Gbps, 2-Port, USB 3.1 Mux/Demux ReDriver with Integrated USB-C Detector Features Description ReDriver PI3EQX10312 is a low-power, high-performance 10Gbps 2-Port USB 3.1 Gen-2/Gen-1 Mux/DeMux ReDriver with Plug-in Detector for 10Gbps Serial Link with Linear Equalizer Type-C connector. Full Compliancy to USB 3.1 Gen-2 and Gen-1 Super-Speed Standard The device includes two main function blocks: 1) The 2 Port Mux/DeMux ReDriver 1-to-2 DeMux from Host Tx to Device Rx 2) The Plug-in Detector for USB-C Connector 2-to-1 Mux from Device Tx to Host Rx Adjustable Output Linear Swing, Flat Gain and The 2 Port Mux/Demux ReDriver Equalization via I2C or Pin Control The ReDriver provides programmable equalization, swing, and flat 100 Differential CML I/Os gain to optimize performance over a variety of physical mediums by Automatic Receiver Detect reducing intersymbol interference. The ReDriver supports two 100 Auto Slumber Mode for Adaptive Power Management differential CML data I/Os between the protocol ASIC to a switch fabric, over cable, or to extend the signals across other distant data Supply Voltage 3.3V pathways on the users platform. Plug-in Detector The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. A low-level input signal USB Type-C Specification 1.3 detection and output squelch function is provided for each channel. Supports SOURCE/SINK/DRP Modes Each channel operates fully independently. The channels input Support DRP Modes with Try.SNK/Try.SRC signal level determines whether the output is active. Auto-Configure Ports Orientation through CC Detection The ReDriver also includes an adaptive power management feature to Supports VCONN to Power Active Cables and Other maximize battery life for power-sensitive consumer devices. Accessories The Plug-in Detector for USB-C Connector Supports Overcurrent Protection and Overvoltage The plug-in detector detects the plug-in orientation of the cable at a Protection for VCONN USB-C connector. It supports the port to configure as SOURCE Allow Both Pin Control and I2C Interface mode, SINK mode, and DRP modes and automatically connects Integrated Power Switches, High-Precision Resistors and based on the voltage levels detected on CC pin. It is a fully-integrated Current Sources for CC Pins solution with ultra-low power dissipation. Provides Support for Default USB Power, 1.5A, and 3A The plug-in detector supports both pin and I2C control based on SOURCE Modes with I2C Control and Pin Control ADDR1 pin setting. It allows the system to choose between pin Output Indicator for Plug-in Detection control and I2C control mode. Power-Saving Mode In pin control mode, the PORT0 and PORT1 input pins determine 24V Tolerance on CC1, CC2 and VBUSDET the port setting in which the SOURCE, SINK, or DRP port can be Power Supply Range: 3.0V to 5.0V selected. In SOURCE and DRP modes, the SRC CUR input pin Temperature Range: -40C to 70C selects USB Type-C current advertisement at default USB, 1.5A, and Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) 3A level. The system running in source mode can monitor ID pin to Halogen and Antimony Free. Green Device (Note 3) know the connector attached or not. Systems running in SINK mode Packaging (Pb-free & Green): can monitor systems VBUS for connector status as well as OUT1, and OUT2 for hosts charging profile capability. DEBUG and OUT3 42-contact, ZH42 (3.5mm 9mm) pins also indicate if a debug or audio accessory is attached. The plug-in detector provides VCONN function to power active Applications cables and other accessories through VCONN pin. Low-resistance Notebooks power switches are integrated in the chip-to-connect CC1/CC2 pins Mobile Phones to VCONN pin. Tablets Enabling I2C control mode allows high flexibility for port control Docking Station and communications through registers read/write. An interrupt signal for indicating changes with the I2C registers is sent to the master to notify the system any change in the USB-C connector while in parallel the system can still monitor ID pin. Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.
