Description

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 Type-C connector.


The device includes two main function blocks:
1) The 2 Port Mux/DeMux ReDriver
2) The Plug-in Detector for USB-C Connector

The 2 Port Mux/Demux ReDriver


The ReDriver provides programmable equalization, swing, and flat gain to optimize performance over a variety of physical mediums by reducing intersymbol interference. The ReDriver supports two 100Ω differential CML data I/Os between the protocol ASIC to a switch fabric, over cable, or to extend the signals across other distant data pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. The channels’ input signal level determines whether the output is active.
The ReDriver also includes an adaptive power management feature to maximize battery life for power-sensitive consumer devices.

The Plug-in Detector for USB-C Connector


The plug-in detector detects the plug-in orientation of the cable at a USB-C connector. It supports the port to configure as SOURCE mode, SINK mode, and DRP modes and automatically connects based on the voltage levels detected on CC pin. It is a fully-integrated solution with ultra-low power dissipation.
The plug-in detector supports both pin and I2C control based on ADDR1 pin setting. It allows the system to choose between pin control and I2C control mode.
In pin control mode, the PORT0 and PORT1 input pins determine the port setting in which the SOURCE, SINK, or DRP port can be selected. In SOURCE and DRP modes, the SRC_CUR input pin selects USB Type-C current advertisement at default USB, 1.5A, and 3A level. The system running in source mode can monitor ID pin to know the connector attached or not. Systems running in SINK mode can monitor system’s VBUS for connector status as well as OUT1, and OUT2 for host’s charging profile capability. DEBUG and OUT3 pins also indicate if a debug or audio accessory is attached.
The plug-in detector provides VCONN function to power active cables and other accessories through VCONN pin. Low-resistance power switches are integrated in the chip-to-connect CC1/CC2 pins to VCONN pin.
Enabling I2C control mode allows high flexibility for port control 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.
