Product details
Overview
PI2DPX1217XUAEX from Diodes Incorporated is a 4-to-4 channel, 10Gbps linear redriver IC supporting USB3.2 Gen2x2, DP1.4/DP2.0 UHBR10 (10Gbps per lane), and DP-Alt mode over USB-C. It integrates an AUX/SBU crossbar switch, operates from a single 1.8V ±5% supply, and delivers ultra-low latency (<300ps) for high-fidelity signal integrity in active cables and docking stations.
For engineers reviewing the PI2DPX1217XUAEX datasheet, PI2DPX1217XUAEX pinout, PI2DPX1217XUAEX application, or PI2DPX1217XUAEX equivalent, key selection criteria include per-channel CTLE/flat gain programmability, I²C-configurable operation modes (USB/DP/DP-Alt), Type-C flip/non-flip support, and industrial temperature range (–40°C to +85°C).
Technical Context
The PI2DPX1217XUAEX implements a non-blocking linear redriver architecture with differential input/output paths that preserve pre-emphasis and de-emphasis waveforms from the source transmitter, enabling system-level DFE-assisted link training. Its CTLE equalizers compensate frequency-dependent channel loss and reduce ISI jitter at each of the four high-speed lanes.
It features an integrated AUX+/AUX− and SBU1/SBU2 crossbar switch supporting Type-C connector orientation detection and dynamic signal routing, plus I²C slave interface (up to 1 MHz) for real-time configuration of CTLE gain, flat gain, and output linearity on a per-channel basis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C DP-Alt linear redriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB1046IRNQT | Retimer architecture (CDR-based), supports USB3.2 Gen2 only, no DP2.0 UHBR10 support | Lacks native DP-Alt mode and AUX/SBU switching; requires external mux for Type-C orientation | Choose when USB-only redriving is sufficient and CDR-based jitter cleanup is preferred over linear transparency |
| Parade PS8815 | Linear redriver with DP1.4 support (not DP2.0/UHBR10), 8Gbps max per lane, no I²C-configurable CTLE | Fixed equalization settings limit adaptability to varying channel loss profiles | Choose for cost-sensitive DP1.4 applications where programmability and UHBR10 headroom are not required |
Compared with TUSB1046IRNQT and PS8815, the PI2DPX1217XUAEX uniquely combines DP2.0 UHBR10 support, per-channel programmable equalization, and integrated AUX/SBU switching-enabling single-chip compliance with next-generation USB-C DP-Alt implementations without external logic.

FAQ
What USB and DisplayPort standards does the PI2DPX1217XUAEX support?
The PI2DPX1217XUAEX supports USB3.2 Gen2 (10Gbps), USB3.2 Gen2x2 (20Gbps aggregate), DP1.4 (8.1Gbps per lane), and DP2.0 UHBR10 (10Gbps per lane) in DP-Alt mode. It is fully compliant with USB-IF and VESA specifications for active cable and docking applications requiring reversible Type-C connectivity.
Does the device require external configuration to operate in USB mode?
No. The PI2DPX1217XUAEX powers up in default USB3.2 Gen2x2 bypass mode, enabling immediate plug-and-play functionality without I²C initialization. I²C configuration is optional and used only to switch to DP-Alt or mixed-mode operations or to tune equalization parameters.
How does the integrated AUX/SBU crossbar switch improve Type-C implementation?
The integrated AUX/SBU crossbar switch dynamically routes AUX+/AUX− and SBU1/SBU2 signals based on CC pin detection, eliminating manual orientation detection logic and external analog switches. This ensures correct sideband communication regardless of plug insertion direction while reducing BOM count and layout complexity.
Is the PI2DPX1217XUAEX suitable for automotive applications?
The PI2DPX1217XUAEX is specified for industrial temperature range (–40°C to +85°C) but is not AEC-Q100 qualified. For automotive use, Diodes Incorporated offers separate AEC-Q100-qualified variants with PPAP documentation and IATF 16949 manufacturing controls-contact Diodes or Aetrix for qualified alternatives.
