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.
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. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm
antimony compounds.
