Product details
Overview
PI3WVR14412Q2ZLCEX from Diodes Incorporated is a 20Gbps 1:2 high-speed signal switch for multi-standard video interfaces, supporting DP2.1, HDMI2.1, MIPI DPHY/CPHY, USB3.2, and LVDS. It features four differential lanes, DDC/AUX + HPD switching, AEC-Q100 Grade 2 qualification (−40°C to +105°C), and 3.3V supply. Used in automotive infotainment head units requiring robust signal integrity and DC-coupled operation.
For engineers reviewing the PI3WVR14412Q2ZLCEX datasheet, PI3WVR14412Q2ZLCEX pinout, PI3WVR14412Q2ZLCEX application, or PI3WVR14412Q2ZLCEX equivalent, key selection criteria include 20Gbps per-lane data rate, −2.0dB insertion loss @10GHz, −30dB channel-to-channel crosstalk, support for both DDC/HPD and AUX/HPD routing, and automotive-grade thermal and reliability validation.
Technical Context
The PI3WVR14412Q2ZLCEX integrates four independent high-speed differential switches with dedicated DDC/AUX and HPD analog signal paths, enabling full protocol-aware switching across DisplayPort 2.1 and HDMI 2.1 topologies. Its wide common-mode range (0 V to VDD) supports DC-coupled operation without AC coupling capacitors.
It employs low-skew, matched trace-length design with 5ps typical bit-to-bit skew and maintains signal fidelity up to 10GHz via −10dB return loss and −15dB off-isolation - critical for maintaining eye diagram integrity in 20Gbps 4-lane configurations used in ADAS camera links and digital cluster displays.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed multi-standard video switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TS3DV642AIPR | Supports up to 12Gbps per lane; no DP2.1 UHBR20 or HDMI2.1 FRL support; requires external level shifters for HDMI DDC | Limited to DP1.4/HDMI2.0; not AEC-Q100 qualified | Use only in non-automotive consumer displays where 20Gbps and automotive qualification are not required |
| Renesas PS8409A-EVK | PCIe Gen3-switch architecture; lacks native HDMI2.1/DP2.1 protocol awareness; no integrated HPD/DDC switching | Designed for PCIe-based docking, not video transport; requires companion I²C mux for display control | Select when PCIe lane aggregation is primary requirement; avoid for direct video interface replacement |
Compared with TS3DV642AIPR and PS8409A-EVK, the PI3WVR14412Q2ZLCEX uniquely delivers 20Gbps per lane with built-in DDC/AUX/HPD switching and AEC-Q100 Grade 2 compliance - making it the only drop-in solution for next-gen automotive display architectures requiring DP2.1 and HDMI2.1 coexistence.

FAQ
Does PI3WVR14412Q2ZLCEX support DP2.1 UHBR20 mode with full 20Gbps per lane?
Yes. The device is characterized for 20Gbps per lane operation per its DS44786 Rev 2-2 datasheet, with insertion loss of −2.0dB @10GHz and −30dB crosstalk - meeting the signal integrity requirements for DP2.1 UHBR20 eye mask compliance in typical 4-layer automotive PCB stackups.
Can PI3WVR14412Q2ZLCEX be used in HDMI2.1 FRL mode without external level shifting?
Yes. Its 0 V to VDD common-mode range supports DC-coupled TMDS signaling at 1.2Vpp differential, eliminating the need for AC coupling capacitors or external level shifters - validated for HDMI2.1 FRL 48G operation with integrated DDC/HPD switching.
What is the thermal pad connection requirement for ZLC package reliability?
The exposed thermal pad must be soldered to a minimum 12 mm² copper pour with ≥4 thermal vias (0.3mm diameter) to internal ground plane. This configuration achieves ≤35°C/W junction-to-board thermal resistance, ensuring safe operation at 105°C ambient in automotive head unit enclosures.
Is PI3WVR14412Q2ZLCEX pin-compatible with earlier PI3WVR14412Q variants?
Yes. All PI3WVR14412Q suffix variants (including ZLCEX, ZLCE, ZLCX) share identical ZLC package footprint, pinout, and electrical behavior. The 'EX' suffix denotes tape-and-reel packaging with extended automotive traceability - no layout or schematic changes required for migration.
