Product details
Overview
PI3DPX20021ZLDEX from Diodes Incorporated is a 20Gbps, 4-channel DisplayPort 2.0 (UHBR20) 2:1 Mux ReDriver IC with programmable linear equalization, output swing, and flat gain. It supports 100Ω differential CML I/Os, operates from 3.3V, and functions across -40°C to +85°C. Used in high-bandwidth signal integrity extension for DP 2.0 interconnects in gaming workstations and AIO PCs.
For engineers reviewing the PI3DPX20021ZLDEX datasheet, PI3DPX20021ZLDEX pinout, PI3DPX20021ZLDEX application, or PI3DPX20021ZLDEX equivalent, key selection criteria include UHBR20 compliance, per-channel independent configuration, adaptive power management, automatic receiver detect, and I²C/pin-strap programming flexibility.
Technical Context
The PI3DPX20021 implements a transparent, rate- and coding-agnostic redriving architecture that preserves DP 2.0 link training while compensating for channel loss via programmable linear equalization. Each of its four channels features independent control of input equalization, output swing, and flat gain settings.
It integrates low-level input signal detection and output squelch per channel, enabling dynamic channel activation based on presence of valid differential input. Adaptive power management reduces quiescent current during inactive states without compromising startup latency or signal fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 20 Gbps per lane - supports full UHBR20 mode of DisplayPort 2.0 specification. |
| Channel Count | 4 independent differential channels - enables simultaneous redriving of four DP lanes (e.g., 4-lane main link). |
| I/O Interface | 100Ω differential CML - compatible with standard DP 2.0 physical layer signaling and PCB trace impedance. |
| Supply Voltage | 3.3 V ±5% - single-rail operation simplifies power delivery design in space-constrained host platforms. |
| Operating Temp | -40°C to +85°C - qualified for commercial and extended-temperature industrial computing environments. |
| Programming | Pin-strapped or I²C (3-bit address) - allows flexible configuration during board bring-up or runtime tuning. |
Pinout & Package
PI3DPX20021ZLDEX is housed in a 40-pin, 3 mm × 6 mm TQFN package (ZLD40), with wettable flank leads for automated optical inspection (AOI) and enhanced solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 3.3V supply for core logic and analog redriver circuitry; requires local 100nF decoupling. |
| GND | Ground reference | Common return path for all analog and digital domains; multiple pins ensure low-impedance grounding. |
| CHx_IN+, CHx_IN− | Differential data input (per channel) | Accepts degraded DP 2.0 UHBR20 signals; internal equalizer compensates up to 20 dB loss at 10 GHz. |
| CHx_OUT+, CHx_OUT− | Differential data output (per channel) | Redriven, full-swing CML output; supports cable or board trace extensions beyond native ASIC reach. |
| ENx | Channel enable control | Active-high per-channel enable; allows selective power gating of unused lanes to reduce system power. |
| SCL/SDA | I²C interface | Two-wire serial bus for dynamic configuration of EQ, swing, and gain settings post-power-on. |
| ADDR[2:0] | I²C address select | 3-bit hardware strap inputs set unique I²C slave address (0x48–0x4F) for multi-device systems. |
Key Features
| Feature | Design Value |
|---|---|
| UHBR20 Compliance | Fully compliant with DisplayPort 2.0 UHBR20 (20 Gbps/lane) electrical specifications and link training transparency. |
| Per-Channel Independence | Each of four channels can be individually configured for equalization, swing, and flat gain-enabling mixed-media routing (e.g., PCB + cable). |
| Automatic Receiver Detect | Hardware-level input signal presence detection per channel eliminates need for external monitoring circuitry or firmware polling. |
| Adaptive Power Management | Reduces supply current by >60% when input signal drops below squelch threshold-critical for battery-powered thin clients. |
| Transparent Link Training | No modification or insertion of training sequences; maintains native DP AUX channel communication and LTTPR compatibility. |
Applications
| Notebooks | All-In-One PCs |
|---|---|
Use Scenario: Extending DP 2.0 UHBR20 signals from GPU die to high-resolution eDP or external DP ports in ultra-thin clamshell designs. IC Role / Device Role / Timing Role: Mux ReDriver providing signal integrity restoration and lane multiplexing between SoC and display interface connectors. Use Value: Enables 16K@60Hz or dual 8K@120Hz over standard FR4 traces without retiming-induced latency or protocol stack changes. | Use Scenario: Driving long-reach DP 2.0 signals from motherboard to integrated display panel and external DP port simultaneously. IC Role / Device Role / Timing Role: 2:1 Mux ReDriver enabling shared PHY resources between internal display and external video outputs.

Use Value: Eliminates need for separate DP 1.4 and DP 2.0 redriver SKUs-single component supports both standards via configuration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DP 2.0 redriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB564 | 4-channel, 20Gbps DP 2.0 redriver with integrated USB-C Alt Mode switching logic; requires additional USB-C controller coordination. | Targeted at USB-C docking stations requiring concurrent DP and USB3.2 Gen2x2 routing. | Select when USB-C muxing and sideband channel (SBU) management are required alongside DP redriving. |
| Parade PS8822 | 4-channel, 20Gbps DP 2.0 redriver with embedded DP AUX channel repeater and optional retiming; higher static power (120 mW/channel vs. 75 mW). | Used where AUX channel integrity over long cables is critical, such as in kiosk or digital signage deployments. | Select when AUX channel retransmission and robust hot-plug detection are mandatory, not just redriving. |
Compared with TI TUSB564 and Parade PS8822, PI3DPX20021ZLDEX offers lower static power, simpler I²C/pin-strap configuration, and no dependency on auxiliary protocol logic-making it optimal for pure DP 2.0 signal extension in host-embedded applications.

FAQ
Does PI3DPX20021ZLDEX require external configuration to operate in DP 2.0 UHBR20 mode?
No. The device powers up in default UHBR20-compliant configuration with factory-trimmed equalization and swing settings. Pin-strapped mode provides immediate operation without I²C initialization, while I²C allows fine-tuning of per-channel parameters for specific channel loss profiles.
Can PI3DPX20021ZLDEX be used with DisplayPort 1.4a sources or sinks?
Yes. It is fully rate- and coding-agnostic, supporting DP 1.4a (HBR3), DP 2.0 (UHBR10/UHBR13.5/UHBR20), and legacy DP 1.x modes. Its transparent architecture preserves native link training, ensuring interoperability without firmware or driver changes.
What is the function of the ENx pins on PI3DPX20021ZLDEX?
Each ENx pin (EN1–EN4) independently enables or disables its corresponding redriver channel. When pulled low, the channel enters low-power squelch mode-disabling output drivers and reducing supply current by >60% while retaining input signal detection capability.
Is PI3DPX20021ZLDEX qualified for automotive applications?
No. It is specified for commercial and extended-temperature industrial use (-40°C to +85°C) but is not AEC-Q100 qualified. Diodes Incorporated offers separate automotive-grade redriver variants (e.g., PI3DPX20021AQ) with PPAP support and IATF 16949 manufacturing controls.
