Product details
Overview
PI3DPX20012ZLDEX from Diodes Incorporated is a 20Gbps, 4-channel DisplayPort 2.0 (UHBR20) 1:2 DeMux ReDriver IC with programmable linear equalization, output swing, and flat gain. It features 100Ω differential CML I/Os, automatic receiver detect per channel, adaptive power management, and operates from 3.3V over –40°C to +85°C in a 40-pin TQFN package. Used in high-bandwidth signal extension for gaming workstations and AIO PCs.
For engineers reviewing the PI3DPX20012ZLDEX datasheet, PI3DPX20012ZLDEX pinout, PI3DPX20012ZLDEX application, or PI3DPX20012ZLDEX equivalent, key selection criteria include UHBR20 compliance, per-channel independent configuration via I²C or pin strap, low-power operation for battery-sensitive platforms, and support for 100Ω differential CML signaling across extended PCB traces or cables.
Technical Context
The PI3DPX20012 implements a transparent, rate- and coding-agnostic redriving architecture that preserves DP 2.0 link training integrity while compensating for channel loss. Its linear equalizer adapts to input signal levels, and each of four independent channels supports configurable receive equalization, transmit swing, and flat gain settings.
It interfaces between DP source ASICs and downstream switch fabrics or display panels using standard 100Ω differential CML signaling. The device includes squelch control per channel and automatic input detection to gate output activity, reducing dynamic power consumption during idle or loss-of-signal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20 Gbps per lane - supports full UHBR20 mode of DisplayPort 2.0 specification. |
| Channels | 4 independent differential lanes - enables 1:2 demultiplexing of DP main link traffic. |
| I/O Interface | 100Ω differential CML - matches standard DP physical layer impedance for minimal reflection and signal integrity loss. |
| Supply Voltage | 3.3 V ±5% - compatible with common system rail; enables direct integration without LDO overhead. |
| Operating Temp | –40°C to +85°C - qualified for commercial and industrial desktop/AIO thermal environments. |
| Control Interface | I²C (3-bit address) or pin strap - allows flexible factory programming or runtime reconfiguration. |
| Power Management | Adaptive per-channel squelch - disables output drivers when input signal falls below threshold, cutting dynamic power in idle states. |
Pinout & Package
Package: 40-pin ZLD (3 mm × 6 mm TQFN), 0.4 mm pitch, exposed thermal pad, RoHS 3 and halogen/antimony-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 3.3V main supply for core logic and I/O drivers; requires local 100nF decoupling. |
| GND | Ground reference | Common return for analog/digital domains; connects to exposed thermal pad for thermal dissipation. |
| IN0+, IN0− | Differential data input (Ch0) | Accepts UHBR20-compliant CML signals from DP source; supports automatic signal detect. |
| OUT0A+, OUT0A− | Differential data output A (Ch0) | Drives first destination (e.g., display panel port A); independently configurable gain/equalization. |
| OUT0B+, OUT0B− | Differential data output B (Ch0) | Drives second destination (e.g., daisy-chained display or alternate path); fully independent of OUT0A. |
| SCL, SDA | I²C interface | Enable runtime configuration of EQ, swing, and flat gain; support up to 8 devices on same bus via 3-bit address. |
| EN0–EN3 | Channel enable inputs | Hardware pin-strap control to activate/deactivate individual channels; overrides I²C settings if asserted. |
Key Features
| Feature | Design Value |
|---|---|
| UHBR20 Compliance | Fully compliant with DisplayPort 2.0 Ultra High Bit Rate 20 (UHBR20) electrical specification for 20 Gbps/lane operation. |
| Per-Channel Independence | Each of four channels has dedicated EQ, swing, and flat gain controls - enables mixed-media routing (e.g., one channel to cable, another to PCB trace). |
| Transparent Link Training | No interference with DP link training sequence - preserves native handshake, clock recovery, and error correction behavior of source/sink. |
| Low-Power Adaptive Operation | Automatic squelch per channel reduces active current by >70% during signal loss or standby - extends battery life in portable workstations. |
| Flexible Configuration | Supports both pin-strapped defaults (for boot-time setup) and I²C reprogramming (for dynamic adaptation) without reset. |

FAQ
Does PI3DPX20012ZLDEX require external configuration to operate?
No. The device supports pin-strapped default settings for equalization, swing, and flat gain, enabling immediate operation without I²C initialization. I²C is optional for dynamic reconfiguration during system runtime or calibration sequences. All channels function independently upon power-up with factory-configured or pin-selected parameters.
Can PI3DPX20012ZLDEX be used in automotive infotainment systems?
Not without qualification. While the PI3DPX20012ZLDEX operates across –40°C to +85°C, it is not AEC-Q100 qualified and is intended for commercial desktop/notebook applications. Diodes offers automotive-grade variants under separate part numbers with PPAP documentation, IATF 16949 manufacturing, and extended reliability testing.
What is the maximum supported trace length for UHBR20 signals with this ReDriver?
At 20 Gbps, the PI3DPX20012ZLDEX compensates for up to 25 dB insertion loss at 10 GHz when configured with maximum equalization. This corresponds to approximately 25 cm of FR4 PCB trace (5-mil width, 5-mil spacing, 4-layer stackup) or 15 cm of 26-AWG shielded DP cable - verified using industry-standard channel models and compliance test fixtures.
Is the thermal pad on the ZLD package electrically connected?
Yes. The exposed thermal pad on the 40-pin ZLD TQFN package is internally connected to ground (GND). It must be soldered to a solid GND plane on the PCB for both thermal performance and signal integrity - floating or unconnected pads degrade EMI performance and increase junction temperature by up to 18°C under full load.
