Diodes Incorporated PI3WVR14412ZLCEX

Overview

PI3WVR14412ZLCEX from Diodes Incorporated is a multi-standard 4-lane, 1:2/2:1 video switch supporting DisplayPort 1.3/1.4/2.0 and HDMI 2.1 with 20 Gbps data rate, -2.0 dB insertion loss @ 10 GHz, and DC-coupled operation up to 1.2 V_PP differential. It routes high-speed video signals between GPU and dual displays in ultrabooks, docking stations, and AV receivers.

For engineers reviewing the PI3WVR14412ZLCEX datasheet, PI3WVR14412ZLCEX pinout, PI3WVR14412ZLCEX application, or PI3WVR14412ZLCEX equivalent, key selection criteria include DP/HDMI multi-standard compatibility, DDC/AUX/HPD mux-demux capability, channel-to-channel crosstalk (-35 dB @ 10 GHz), off-isolation (-15 dB @ 10 GHz), and TQFN-40 (3 × 6 mm) package thermal performance.

Technical Context

The PI3WVR14412ZLCEX implements a bidirectional, logic-controlled analog switch matrix for four high-speed differential lanes (D0–D3), plus dedicated DDC/AUX and HPD signal routing paths. It supports both DP AUX channel (720 Mbps) and HDMI DDC (100 kHz–400 kHz) with independent select control via GPU_SEL and DDC/AUX_HPD_SEL pins.

Its DC-coupled architecture accepts 0–V_DD common-mode voltage and 1.2 V_PP differential swing, eliminating AC coupling capacitors. The device operates from 3.3 V ±10% and maintains <5 ps bit-to-bit skew between complementary pairs across all lanes.

FAQ

Does PI3WVR14412ZLCEX support HDCP encryption pass-through?

No. The PI3WVR14412ZLCEX is a physical-layer analog switch and does not process or decrypt HDCP content. It transparently passes encrypted TMDS or DP link training sequences, enabling downstream HDCP authentication to occur end-to-end between source and sink devices without interruption.

Can PI3WVR14412ZLCEX operate with 1.8 V I/O control logic?

No. The logic control pins (GPU_SEL, OE, DDC/AUX_HPD_SEL) require 3.3 V CMOS levels and are not 1.8 V tolerant. Driving them below 2.0 V may result in undefined state transitions; a level shifter is required if interfacing with 1.8 V microcontrollers.

What is the thermal resistance (θ_JA) of the ZLC package?

The TQFN-40 ZLC package has a typical θ_JA of 42 °C/W under JEDEC JESD51-7 4-layer board conditions (1 in² 2 oz Cu, 10 vias). With the exposed thermal pad soldered to a 200 mm² internal ground plane, θ_JA improves to ≤31 °C/W, supporting continuous 20 Gbps operation at ambient ≤70 °C.

Is PI3WVR14412ZLCEX qualified for automotive AEC-Q100 Grade 2?

No. This part is not AEC-Q100 qualified. Diodes Incorporated offers the PI3WVR14412QZLE as the automotive-grade variant (AEC-Q100 Grade 2, -40°C to +105°C), with identical functionality but manufactured in IATF 16949-certified facilities and PPAP-capable documentation.
