Back to Signal Integrity - ReDrivers™/Repeaters/Signal Conditioners


USB 3.2 Gen 2x2 ReDriver, 3.3V, Type C Port, CC Controller


The PI3EQX2034 is a low power, high performance USB 3.2 Gen 2x2 ReDriver™ with Plug-in Detector for Type-C® connector. The Device includes two main function blocks:

1) The USB3.2 Gen2x2 ReDriver

2) The Plug-in Detector for USB-C connector

The USB3.2 Gen2x2 ReDriver

The ReDriver provides programmable equalization, swing and flat gain to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. The ReDriver supports four 100Ω Differential CML data I/O’s 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 (DFP) 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 interfaces. The PORT input pins determine the port setting in which the SOURCE 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. DEBUG pin also indicate if a debug 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.

 I2C interface informs the processor the information of connection and plug orientation. An interrupt signal for indicating changes.
