Product details
Overview
PI3WVR13612ZLEX from Diodes Incorporated is a 4-lane, 1:2/2:1 multi-standard video switch supporting DisplayPort 1.3/1.4 (HBR3, 8.1 Gbps) and HDMI 2.0, with integrated switching of AUX/DDC/HPD signals. It operates from 3.3 V ±10%, delivers -1.6 dB insertion loss at 4.05 GHz, and supports DC-coupled operation up to 1.2 VPP differential with 0–3.4 V common-mode range for compact, high-density PCB routing in docking stations and embedded display hubs.
For engineers reviewing the PI3WVR13612ZLEX datasheet, PI3WVR13612ZLEX pinout, PI3WVR13612ZLEX application, or PI3WVR13612ZLEX equivalent, key selection criteria include its 7 GHz -3 dB bandwidth, 35 ps max channel-to-channel skew, -35 dB crosstalk at 4.05 GHz, dual HPD switching capability, and TQFN-52 (3.5 × 9.0 mm) package compatibility with high-speed layout constraints.
Technical Context
The PI3WVR13612ZLEX implements a fully differential 4-lane switch matrix with independent control for high-speed DP/HDMI lanes, plus dedicated 1-channel HPD and differential AUX/DDC switch paths. Its architecture enables simultaneous RBR/HBR1/HBR2/HBR3 and HDMI 2.0 TMDS signal routing without AC coupling.
Logic control includes GPU_SEL, DDC_AUX_SEL, and OE inputs to configure 1:2 or 2:1 topology per signal group. The device maintains signal integrity via matched trace lengths (35 ps skew), low off-isolation (-20 dB @ 4.05 GHz), and 720 Mbps DP AUX support - all within a single 52-pin TQFN package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 8.1 Gbps per lane - supports DisplayPort HBR3 and HDMI 2.0 full bandwidth |
| -3 dB Bandwidth | 7 GHz - preserves signal integrity through third-harmonic of 4.05 GHz fundamental |
| Insertion Loss | -1.6 dB @ 4.05 GHz - minimizes amplitude degradation in high-speed differential pairs |
| Crosstalk | -35 dB @ 4.05 GHz - prevents inter-lane interference in dense 4-lane routing |
| VDD Range | 3.3 V ±10% - compatible with standard logic supply rails and noise margins |
| ESD Tolerance | 1.5 kV HBM - provides robust handling during board assembly and system integration |
| Channel Skew | 35 ps max - ensures timing alignment across all four high-speed lanes |

Key Features
| Feature | Design Value |
|---|---|
| DC-coupled multi-standard operation | Eliminates 8–12 AC coupling capacitors per design, reducing BOM count and PCB area in space-constrained docks |
| 720 Mbps DP AUX switching | Meets DisplayPort 1.4 AUX channel timing requirements for link training and EDID reads |
| Matched 35 ps channel skew | Ensures deterministic eye alignment across all four lanes, critical for HBR3 compliance |
| Integrated HPD switching (1-channel 1:2/2:1) | Allows independent hot-plug signaling to two displays without external logic or muxing |
| Low -20 dB off-isolation @ 4.05 GHz | Prevents signal leakage into inactive paths, maintaining signal fidelity during dynamic reconfiguration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-standard video switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642RHAR | 64-pin VQFN; supports only DP 1.2/HDMI 1.4 (5.4 Gbps); no integrated HPD switching | Limited to lower bandwidth; requires external HPD logic and AC coupling caps | Choose when cost sensitivity outweighs HBR3 support and board space constraints |
| PI3WVR41312ZLEX | Same ZL package; 4-lane but 1:1 + bypass mode only; no 1:2/2:1 HPD or AUX switching | Designed for signal conditioning, not dynamic source/sink arbitration | Select only for fixed-path retiming or equalization, not active switching topologies |
Compared with TS3DV642RHAR and PI3WVR41312ZLEX, the PI3WVR13612ZLEX uniquely integrates full 4-lane 1:2/2:1 switching, dual HPD control, and DC-coupled operation - enabling single-chip solutions for dynamic multi-display arbitration without external components or bandwidth compromise.

FAQ
What voltage levels does the PI3WVR13612ZLEX support on its high-speed lanes?
The PI3WVR13612ZLEX supports differential signals from 0.2 VPP to 1.2 VPP with a common-mode range of 0 V to 3.4 V. This wide range enables direct DC coupling with DisplayPort 1.3/1.4 and HDMI 2.0 sources without AC coupling capacitors, preserving low-frequency content and reducing PCB area.
Does the PI3WVR13612ZLEX require external termination resistors?
No. The PI3WVR13612ZLEX integrates 100 Ω differential termination on all high-speed lanes internally. This eliminates the need for external 50 Ω resistors to ground per side, simplifying layout and ensuring consistent impedance matching across temperature and process variation.
How is HPD switching implemented in the PI3WVR13612ZLEX?
The device provides two dedicated HPD output pins (HPDA and HPDB) driven by internal logic that mirrors the active source's HPD state. When configured in 1:2 mode, HPDA and HPDB independently assert/deassert based on GPU_SEL and OE, enabling true dual-sink hot-plug detection without external GPIO or level shifters.
Can the PI3WVR13612ZLEX be used in HDMI-only applications without DisplayPort signals?
Yes. The PI3WVR13612ZLEX supports HDMI 2.0 TMDS lanes at 6 Gbps per channel (18 Gbps total) in addition to DP. Its wide common-mode range (0–3.4 V) and 7 GHz bandwidth accommodate HDMI 2.0's voltage swing and harmonics, and its DDC switching handles HDMI's I²C-based EDID communication natively.
