Product details
Overview
PI3DPX8100ZLDEX from Diodes Incorporated is a 3.3V, 4-lane DisplayPort 1.4 (8.1 Gbps) 2-to-1 active multiplexer switch with integrated linear redriver functionality. It supports RBR/HBR/HBR2/HBR3 data rates, provides up to +8.8 dB CTLE equalization at 4.05 GHz, and implements LTTPR-compliant redriver data path architecture for transparent link training. It is used in docking stations and KVM switches to route DP signals between two upstream sources and one downstream display.
For engineers reviewing the PI3DPX8100ZLDEX datasheet, PI3DPX8100ZLDEX pinout, PI3DPX8100ZLDEX application, or PI3DPX8100ZLDEX equivalent, key selection criteria include its 2-to-1 mux topology, LT-tunable redriver support, quad-level pin-strapped EQ/flat gain control, and TQFN-40 (3×6 mm) package compatibility with high-density DP interconnect layouts.
Technical Context
The PI3DPX8100 implements a dual-input, single-output 4-lane DP mux with independent differential channel paths per lane (DP0–DP3), each featuring programmable CTLE equalization and flat-gain linear redriver stages. Its LT-tunable architecture preserves link training packets end-to-end, enabling full PHY-layer transparency for DP1.4 compliance.
Control is implemented via combinational logic on AFS/BFS/PD pins, selecting among four discrete EQ gain levels (0 to +8.8 dB), three flat gain settings, and two output swing linearity modes. Input signal detection enables automatic entry into low-power mode when no valid DP signal is present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 8.1 Gbps per lane (DP1.4 HBR3), supporting full RBR/HBR/HBR2/HBR3 link training. |
| Equalization Gain | +8.8 dB max CTLE boost at 4.05 GHz; compensates PCB trace loss up to ~15 dB at Nyquist frequency. |
| Supply Voltage | 3.3 V ±0.3 V; single-rail operation eliminates need for auxiliary voltage rails. |
| Operating Temp | 0°C to +70°C commercial range; validated for laptop dock and peripheral enclosure thermal profiles. |
| Redriver Type | LTTPR-compliant linear redriver; passes link training sequences without modification for system-level PHY negotiation. |
| Control Interface | Pin-strapped logic (AFS/BFS/PD); no I²C or configuration register required-reduces BOM and layout complexity. |
Pinout & Package
Package: ZLD - 40-pin, 3 mm × 6 mm, 0.4 mm pitch TQFN with exposed thermal pad (RoHS-compliant, halogen-free, green).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DP0A+/DP0A− | Lane 0 differential input A | Primary upstream DP source lane 0 input pair; accepts AC-coupled 100 Ω differential signals. |
| DP1A+/DP1A− | Lane 1 differential input A | Primary upstream DP source lane 1 input pair; routed through same mux path as DP0A for synchronized switching. |
| Out0+/Out0− | Lane 0 differential output | Single downstream DP sink lane 0 output; drives 100 Ω differential load with pre-emphasis and de-emphasis waveform fidelity. |
| AFS/BFS/PD | Configuration logic inputs | Three-pin strap determines EQ gain level, flat gain setting, and output swing linearity mode at power-up. |
| VDD / GND | Power supply terminals | Single 3.3 V rail powers all redriver channels and internal logic; requires local 100 nF + 10 µF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| 2-to-1 Active Mux Topology | Enables seamless switching between two DP sources (e.g., laptop + desktop) to one monitor without signal interruption or retraining delay. |
| LT-Tunable Redriver Architecture | Maintains full DP link training packet integrity across redriver path, satisfying DP1.4 LTTPR PHY repeater requirements. |
| Quad-Level EQ Gain Control | Four selectable CTLE settings (0 / +3.5 / +6.0 / +8.8 dB) allow precise compensation for varying channel insertion loss. |
| Input Signal Detection | Automatically disables unused redriver lanes and enters low-power state when no valid DP signal is detected-reducing idle power by >40%. |
| Halogen- & Antimony-Free "Green" Design | Meets RoHS 3 (2015/863/EU) with Br+Cl <1500 ppm and Sb <1000 ppm-qualified for eco-sensitive industrial and consumer deployments. |
Applications
| Docking Stations | KVM Switches |
|---|---|
Use Scenario: Dual-source laptop/desktop sharing a single high-resolution DP monitor via USB-C or Mini-DP port. IC Role / Device Role / Timing Role: 2-to-1 active mux selects upstream source; redriver restores signal integrity over extended flex-cable or PCB trace runs. Use Value: Eliminates manual retraining delays during source switching and maintains 4K@60Hz + HDR timing stability across both inputs. | Use Scenario: Centralized control of multiple computers using one keyboard/video/mouse set with DP video routing. IC Role / Device Role / Timing Role: Acts as DP lane selector and signal conditioner to preserve eye opening across long backplane traces and connector interfaces. Use Value: Enables zero-frame-drop video handoff between systems while meeting DP1.4 electrical compliance at 8.1 Gbps. |
| Workstation Monitors | PC Peripherals |
Use Scenario: High-end monitor with dual DP inputs accepting graphics outputs from GPU and integrated graphics simultaneously. IC Role / Device Role / Timing Role: Mux + redriver ensures clean signal delivery to internal timing controller regardless of selected input source. Use Value: Supports simultaneous multi-GPU hot-plug detection and maintains consistent EDID handshake behavior across both DP ports. | Use Scenario: USB-C hub with DP Alt Mode output driving external displays from mobile devices or thin clients. IC Role / Device Role / Timing Role: Compensates for signal degradation caused by compact internal routing and low-profile connectors. Use Value: Delivers stable 4K@60Hz output even with 15 cm internal flex traces and unshielded board stackups. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DisplayPort 1.4 redriver-mux applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB546IRWBR | Single-input, 1-to-2 redriver; lacks 2-to-1 mux capability and LTTPR transparency-requires host-side link training management. | Suitable only for downstream fanout (one source → two sinks), not source selection. | Select when expanding DP output count-not for source switching. |
| Parade PS8409B | Integrated MCU-based DP retimer with I²C configuration; higher latency and firmware dependency vs. pin-strapped analog redriver. | Supports dynamic EQ tuning and HDCP forwarding but adds BOM cost and boot-time overhead. | Select when adaptive link optimization or content protection passthrough is required. |
Compared with TI TUSB546IRWBR and Parade PS8409B, the PI3DPX8100ZLDEX uniquely combines 2-to-1 analog muxing, LTTPR-transparent redriving, and zero-config pin-strapped tuning-enabling deterministic, low-latency DP source switching without host intervention or firmware.

FAQ
Does PI3DPX8100ZLDEX support DisplayPort 2.0 or UHBR speeds?
No. The PI3DPX8100ZLDEX is specified only for DisplayPort 1.4 with maximum data rate of 8.1 Gbps per lane (HBR3). It does not support DP2.0's UHBR10/13.5/20 speeds, nor does its CTLE bandwidth or redriver architecture meet UHBR jitter or equalization requirements.
Can AFS/BFS/PD pins be left floating or must they be tied?
All three control pins (AFS, BFS, PD) must be actively pulled HIGH or LOW using 10 kΩ resistors to VDD or GND. Floating states are undefined and may cause inconsistent EQ gain, flat gain, or output linearity selection-leading to signal integrity failures or unstable link training.
Is thermal pad soldering required for reliable operation?
Yes. The exposed thermal pad on the ZLD TQFN package must be soldered to a dedicated PCB thermal land with ≥6 thermal vias to internal ground planes. Omitting this compromises junction temperature rise, risking thermal shutdown or accelerated parametric drift above 65°C ambient.
Does PI3DPX8100ZLDEX pass DisplayPort certification tests (e.g., VESA CTS)?
Yes. Diodes Incorporated validates the PI3DPX8100 against VESA DisplayPort Compliance Test Specification (CTS) 1.4a, including eye diagram, jitter tolerance, link training robustness, and LTTPR transparency-certification reports are available under NDA from Diodes' technical support.
