Product details
Overview
PI3DPX1207Q3ZHEX from Diodes Incorporated is a USB Type-C DP-Alt mode linear redriver IC supporting DP1.4 (8.1 Gbps) and USB3.1 Gen2/USB3.2 (10 Gbps), AEC-Q100 Grade 3 qualified (−40°C to +85°C), with integrated AUX switch and AUX listener, used in automotive infotainment systems for signal integrity restoration across high-speed DisplayPort and USB differential links.
For engineers reviewing the PI3DPX1207Q3ZHEX datasheet, PI3DPX1207Q3ZHEX pinout, PI3DPX1207Q3ZHEX application, or PI3DPX1207Q3ZHEX equivalent, key selection criteria include linear equalization support for transparent DP Link Training, independent EQ/gain/swing control per protocol, I²C-configurable multi-mode operation (4×DP / 1×USB+2×DP / 1×USB / 2×USB), and automotive-grade thermal and reliability validation.
Technical Context
This redriver implements non-blocking linear equalization to preserve receiver DFE adaptability and enable native Transparent DP Link Training without AUX channel dependency. It supports latency-free USB read/write transfers and variable frame rate video timing synchronization via DP redriver link training.
The device integrates dual-function AUX circuitry: an analog switch for Type-C plug orientation flipping and a dedicated AUX listener that triggers DP D3 power-down during pin-control mode. Configuration is supported exclusively via slave I²C (up to 1 MHz) or hardware pin strapping - no SPI or GPIO-based register access.
Key Specifications

FAQ
Does PI3DPX1207Q3ZHEX support USB3.2 Gen2x2 (20 Gbps)?
No. The device supports USB3.1 Gen2 and USB3.2 Gen2 (10 Gbps per lane), not Gen2x2. Its architecture is designed for single-lane 10 Gbps operation with independent lane control. USB3.2 Gen2x2 requires dual-lane aggregation and different PHY-level signaling not implemented in this redriver.
Can PI3DPX1207Q3ZHEX operate without I²C configuration?
Yes. All operational modes (4×DP, 1×USB+2×DP, etc.) and signal parameters (EQ/gain/swing) can be set via hardware pin strapping. I²C is optional for dynamic reconfiguration; default pin-control settings enable immediate functionality after power-up.
Is the AUX listener function active in both I²C and pin-control modes?
The AUX listener operates only in pin-control mode, where it monitors AUX activity to autonomously trigger DP D3 power-down. In I²C mode, D3 control is managed exclusively via register writes - the listener circuit is disabled to prevent conflict with host-driven state management.
What is the maximum allowable channel loss compensation capability?
The redriver provides up to 15 dB of linear equalization per channel at 5 GHz, sufficient to compensate for ≥20 dB insertion loss in typical automotive FPC-to-PCB interconnects. Measured eye opening improvement exceeds 0.25 UI at 10 Gbps under worst-case loss profiles per Diodes' application note AN-5012.
