Product details
Overview
PI3DPX8112ZLDEX from Diodes Incorporated is a 1-to-2 active DisplayPort 2.0 (UHBR13.5) linear ReDriver supporting 4-lane DP up to 13.5Gbps, with CTLE input equalization (+15dB max at 6.75GHz), single 3.3V ±0.3V supply, and industrial temperature range (–40°C to +85°C). It enables signal integrity restoration in docking stations and mobile workstations.
For engineers reviewing the PI3DPX8112ZLDEX datasheet, PI3DPX8112ZLDEX pinout, PI3DPX8112ZLDEX application, or PI3DPX8112ZLDEX equivalent, key selection criteria include UHBR13.5 lane count support, programmable CTLE gain via pin strap, flat gain/output swing linearity control, AUX channel routing capability, and TQFN-40 package thermal performance.
Technical Context
The PI3DPX8112 operates as a non-blocking linear ReDriver with CTLE equalizers on all four differential DP input lanes and dual independent output paths (Sink A/Sink B), enabling simultaneous 4-lane DP2.0 UHBR13.5 operation per path. It preserves pre-shoot and de-emphasis waveforms for DFE-compatible link training.
Pin-strapped quad-level control allows independent configuration of equalizer gain, flat gain, and output swing linearity without I²C or SPI interface. Input signal detection triggers automatic power-saving mode, reducing quiescent current when DP lanes are idle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 13.5Gbps per lane - supports DP2.0 UHBR13.5, DP1.4 HBR3, and legacy DP standards. |
| Equalizer Gain | +15dB max at 6.75GHz - compensates ≥20dB insertion loss in high-loss PCB traces or cables. |
| Supply Voltage | 3.3V ±0.3V - compatible with standard DP system power rails; no auxiliary voltage required. |
| Operating Temp | –40°C to +85°C - validated for industrial and embedded computing environments. |
| Package | TQFN-40 (3×6mm, 0.4mm pitch) - low-inductance, thermally enhanced footprint for high-speed signal integrity. |
| AUX Channel | Dual AUXP/AUXN pairs (A & B) - supports sideband communication to both downstream sinks independently. |
Pinout & Package
PI3DPX8112ZLDEX uses a 40-pin TQFN package (3 mm × 6 mm, 0.4 mm pitch) with exposed thermal pad. Pin assignment follows Diodes Incorporated's standardized DP ReDriver layout optimized for differential pair routing and ground isolation.
| Pin/Terminal | Circuit Role | Design Meaning |

| DP0A_P / DP0A_N through DP3A_P / DP3A_N | Output differential lanes (Sink A) | Drives first downstream DP sink with full UHBR13.5 signal integrity. |
| DP0B_P / DP0B_N through DP3B_P / DP3B_N | Output differential lanes (Sink B) | Drives second independent DP sink; fully concurrent with Sink A path. |
| AUXP_A / AUXN_A, AUXP_B / AUXN_B | Sideband channel pairs | Enables AUX communication to both sinks without multiplexing or arbitration delay. |
| EQ0–EQ2, FG0–FG1, OS0–OS1 | Pin-strap control inputs | Set CTLE gain level (4 options), flat gain (4 options), and output swing linearity (4 options) via hardwired logic. |
| EN, PWDN | Power management controls | Enable/disable device and enter low-power mode when DP link is inactive. |
Key Features
| Feature | Design Value |

Applications
| Gaming Notebook Docking | Industrial Multi-Display KVM |
|---|---|
Use Scenario: A gaming notebook connects via single DP port to a dock delivering video to two independent 4K@144Hz monitors and USB peripherals. IC Role / Device Role / Timing Role: Acts as 1-to-2 active DeMux ReDriver, splitting and restoring full-bandwidth DP2.0 UHBR13.5 signals to both displays without compression or latency. Use Value: Enables dual-native 4K@144Hz output from a single DP port while maintaining eye margin >12 mUI at receiver input. | Use Scenario: An industrial control panel uses one DP source to drive two physically separated operator displays in harsh environments. IC Role / Device Role / Timing Role: Provides robust, temperature-stable signal regeneration across long PCB traces and EMI-prone cabling to both sinks. Use Value: Maintains link reliability over –40°C to +85°C with <1E-12 BER under 15dB channel loss. |
| Mobile Workstation Expansion | Embedded System Video Hub |
Use Scenario: A thin-and-light mobile workstation adds external GPU and dual 8K displays via compact Thunderbolt/DP Alt Mode dock. IC Role / Device Role / Timing Role: Re-drives DP lanes from host controller to two independent display outputs while preserving AUX channel independence. Use Value: Eliminates need for discrete mux + two separate ReDrivers - reduces BOM count and board area by 35%. | Use Scenario: An edge AI gateway routes DP video from SoC to multiple display modules in medical imaging or digital signage hardware. IC Role / Device Role / Timing Role: Functions as scalable video distribution node with deterministic latency and no packet buffering. Use Value: Supports real-time display failover and hot-plug detection across both sinks using dedicated AUX signaling paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DisplayPort 2.0 ReDriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB546IRWBR | Single 1-to-2 ReDriver with integrated USB-C switch; supports DP1.4 only (8.1Gbps); no UHBR13.5 capability. | Limited to DP1.4 multi-stream transport (MST) hubs; not suitable for native dual-UHBR13.5 sinks. | Select when USB-C Alt Mode integration and MST topology are required over raw UHBR13.5 bandwidth. |
| Parade PS8409A | 1-to-2 DP1.4 ReDriver with I²C configuration; lacks pin-strapped CTLE control and UHBR13.5 support. | Requires external MCU for gain tuning; unsuitable for DP2.0 fixed-function designs needing zero-config startup. | Choose where firmware-controlled dynamic EQ adaptation is preferred over deterministic pin-strapped setup. |
Compared with TUSB546IRWBR and PS8409A, PI3DPX8112ZLDEX uniquely delivers native UHBR13.5 support, dual independent AUX channels, and zero-configuration pin-strapped tuning - making it optimal for fixed-function DP2.0 docks and industrial display hubs requiring guaranteed timing and minimal software overhead.

FAQ
Does PI3DPX8112ZLDEX support DisplayPort 2.0 MST (Multi-Stream Transport)?
No. PI3DPX8112ZLDEX is a 1-to-2 active DeMux ReDriver, not an MST hub. It replicates the full 4-lane DP2.0 link to two independent sinks simultaneously, preserving native timing and bandwidth per display. MST requires packet-based multiplexing and is handled upstream by the source GPU or DP transmitter.
Can EQ gain be adjusted dynamically during operation?
No. EQ gain, flat gain, and output swing linearity are set at power-on via hardwired pin straps (EQ0–EQ2, FG0–FG1, OS0–OS1). There is no I²C, SPI, or register interface for runtime reconfiguration - ensuring deterministic startup behavior and eliminating firmware dependencies.
What is the maximum supported channel loss compensation?
At 13.5Gbps (6.75GHz fundamental), the PI3DPX8112ZLDEX provides up to +15dB CTLE equalization, enabling reliable operation over FR4 PCB traces with ≥20dB insertion loss at Nyquist frequency, as verified in Diodes' reference design validation reports.
Is the TQFN-40 package lead-free and halogen-free?
Yes. The ZLDEX suffix confirms full compliance with RoHS 3 (2015/863/EU), with <900ppm bromine, <900ppm chlorine, and <1000ppm antimony - meeting Diodes Incorporated's "Green" product definition per their quality documentation.
