Diodes Incorporated PI2DPX1263XUAEX

Overview

PI2DPX1263XUAEX from Diodes Incorporated is a 4-channel, 1.8V, 10Gbps DisplayPort 2.0/1.4 linear ReDriver with integrated AUX channel listener, supporting UHBR10 (10 Gbps), HBR3 (8.1 Gbps), and backward-compatible DP speeds; used in high-bandwidth display interconnects for laptop PCs, gaming consoles, and VR/AR goggle systems.

For engineers reviewing the PI2DPX1263XUAEX datasheet, PI2DPX1263XUAEX pinout, PI2DPX1263XUAEX application, or PI2DPX1263XUAEX equivalent, key selection criteria include ultra-low latency (<300 ps), per-channel CTLE/flat gain/linearity programmability via I²C, D3 power-saving mode support through AUX listener, and industrial temperature range (–40°C to +85°C).

Technical Context

The PI2DPX1263XUAEX implements a non-blocking linear ReDriver architecture that preserves pre-shoot and de-emphasis waveforms across all four DP lanes, enabling full DFE-based link training between source and sink. Its on-die CTLE equalizers compensate channel loss and reduce ISI jitter at each input.

It integrates an AUX channel listener that monitors DPCD register traffic to autonomously trigger D3 power-saving mode and dynamically activate negotiated lane count. I²C slave interface supports up to 1 MHz clock rate for real-time configuration of per-channel gain, flat gain, and output linearity settings.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported DisplayPort version and data rate?

The PI2DPX1263XUAEX supports DisplayPort 2.0 at UHBR10 (10 Gbps per lane) and is backward compatible with DP 1.4 (HBR3 at 8.1 Gbps), HBR2 (5.4 Gbps), and RBR (2.7 Gbps). It maintains full compliance with DP2.0 link training, including LTTPR compatibility and DPCD 1.5 register mapping.

Does the device require external configuration to enter D3 power-saving mode?

No. The integrated AUX channel listener autonomously detects DPCD register traffic patterns and triggers D3 entry without host processor involvement. This hardware-based behavior reduces system firmware complexity and ensures deterministic low-power transitions during display idle periods.

Can channel polarity be swapped without modifying the PCB layout?

Yes. The PI2DPX1263XUAEX supports hardware-level polarity interchange on each of its four differential channels via dedicated register bits. This eliminates the need for physical trace swapping or board revisions when addressing layout mismatches or connector orientation changes.

Is the I²C interface compatible with standard 1 MHz controllers?

Yes. The I²C slave interface operates at up to 1 MHz with standard open-drain signaling and supports repeated start conditions. All configuration registers-including per-channel CTLE, flat gain, and linearity-are accessible within this timing, enabling real-time tuning during link training or runtime adaptation.
