Product details

Overview

PI3WVR31310AZLEX from Diodes Incorporated is a 3:1 HDMI/DP multiplexer or 1:3 demultiplexer switch supporting HDMI 2.0 (6 Gb/s) and DisplayPort 1.2 (5.4 Gb/s), with four high-speed differential lanes, AUX/DDC, HPD, and CAB_DET channels. It operates from a 3.3 V supply, features ESD protection (2 kV HBM), and enables manual or HPD-driven auto-port selection in demux mode for notebook, monitor, and TV sink applications.

For engineers reviewing the PI3WVR31310AZLEX datasheet, PI3WVR31310AZLEX pinout, PI3WVR31310AZLEX application, or PI3WVR31310AZLEX equivalent, key selection criteria include DP/HDMI dual-mode configuration, HPD direction control via DEMUX_MUX, priority-based port arbitration using PRI_SEL, and passive-switch R_ON ≤ 12 Ω on high-speed lanes.

Technical Context

The device implements a bidirectional passive analog switch architecture for high-speed differential signals, with independent switching control for D[0:3]P/N, AUX/DDC, HPD, and CAB_DET paths. Its dual-mode operation (DP or HDMI) is selected by the DP_HDMI pin, and port routing is determined by SEL1/SEL0 in manual mode or HPD detection with configurable priority (PRI_SEL = 0, 1, or M).

In 1:3 demux mode, HPD1/2/3 serve as inputs with internal 120 kΩ pull-downs, while HPD_SRC acts as an output; in 3:1 mux mode, HPD_SRC becomes an input and HPD1/2/3 become outputs. The switch supports both HDMI-sink-only operation and DP-source-to-sink demuxing, with no HDMI-source capability.

Key Specifications

Parameter	Value and Actual Design Meaning
High-speed data rate	HDMI 2.0 at 6 Gb/s or DP 1.2 at 5.4 Gb/s - enables full UHD 4K@60Hz video transport
R_ON (HS channel)	8–12 Ω - ensures minimal insertion loss and signal integrity for differential pairs
V_pass (DDC path)	1.5–2.5 V at 5 V input - level-shifts DDC signals to 3.3 V logic domain safely
HPD buffer drive	VOH ≥ 2.4 V / VOL ≤ 0.4 V at 4 mA - meets HDMI/DP sink-side HPD voltage compliance
Supply voltage	3.0–3.6 V - compatible with standard 3.3 V system rails and tolerates ±10% variation
ESD rating	2 kV HBM on all I/O pins - provides robust board-level ESD immunity without external protection
Switching time	1 µs (manual port change) - enables rapid reconfiguration during display hot-plug events

Pinout & Package

Package: 60-pin TQFN (5 mm × 9 mm), exposed thermal pad (EPAD) connected to GND.

Pin/Terminal	Circuit Role	Design Meaning
D0P–D3N	Main high-speed differential input	Accepts DP/HDMI source data lanes; routed to selected port based on SEL1/SEL0 or HPD priority
D0P1–D3N1, D0P2–D3N2, D0P3–D3N3	Port-specific high-speed differential outputs	Deliver switched video/data to three independent sinks; each set corresponds to one physical port
AUXP/AUXN, SDA/SCL	AUX channel (DP) or DDC channel (HDMI) interface	Bi-directional auxiliary signaling path; function depends on CAB_1/2/3 state and DP_HDMI mode
HPD_SRC, HPD1–HPD3	Hot Plug Detect I/O	Direction reverses between mux/demux modes; enables automatic port selection and sink notification
DEMUX_MUX, DP_HDMI, SEL1/SEL0, PRI_SEL, OEB	Configuration and control inputs	Digital logic pins that define topology (mux/demux), protocol (DP/HDMI), port selection method, and power enable

Key Features

Feature	Design Value
Configurable topology	Single device supports both 3:1 mux and 1:3 demux via DEMUX_MUX pin - reduces BOM count and layout complexity
Auto-port arbitration	PRI_SEL selects among three HPD priority sequences (port1/port2/port3, port2/port3/port1, port3/port1/port2) - eliminates firmware dependency for plug-and-play sink selection
Dual-protocol compatibility	Pin-selectable DP or HDMI mode with dedicated AUX/DDC routing - avoids separate switches for different display interfaces
Integrated HPD buffering	CMOS HPD drivers support 5 V input tolerance and meet HDMI/DP sink electrical specs - removes need for external level shifters
Low-power standby	OEB-controlled shutdown draws ≤10 µA in DP mode - extends battery life in portable display systems

Applications

Notebook Display Hub

Monitor Input Selector

Use Scenario: A laptop connects to multiple external displays via USB-C or miniDP, requiring dynamic routing of video/audio to one active monitor.

IC Role / Device Role / Timing Role: Acts as a 1:3 DP demux with HPD auto-priority selection - detects which monitor is powered and routes signal accordingly.

Use Value: Enables seamless hot-plug detection and zero-latency port switching without OS driver intervention or manual menu navigation.

Use Scenario: A desktop monitor accepts inputs from PC, game console, and media player, allowing user-selected source switching.

IC Role / Device Role / Timing Role: Functions as a 3:1 HDMI mux with manual port selection via SEL1/SEL0 - routes HDMI 2.0 video from any source to the panel.

Use Value: Supports full-bandwidth 4K@60Hz across all inputs with <1 µs switching latency and no signal degradation due to low R_ON.

AV Switch Box

TV HDMI Sink Aggregation

Use Scenario: Consumer AV switch box consolidates three HDMI sources into one output for connection to a single TV or projector.

IC Role / Device Role / Timing Role: Serves as a 3:1 HDMI mux with DDC passthrough and HPD forwarding - maintains EDID communication and sink readiness.

Use Value: Preserves HDCP handshaking and audio return channel (ARC) functionality through integrated DDC switching and level translation.

Use Scenario: Smart TV design integrates multiple HDMI inputs (e.g., STB, Blu-ray, streaming stick) with shared processing pipeline.

IC Role / Device Role / Timing Role: Operates as a 3:1 HDMI mux with CAB_DET support - detects cable presence and prevents false HPD assertions from unterminated ports.

Use Value: Reduces false hot-plug interrupts and improves system reliability by validating physical connection before enabling signal path.

Equivalent & Alternatives

The following parts are listed as comparable options for similar HDMI/DP switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PI3WVR31310A	Same die, non-tape-and-reel packaging (ZLE suffix); identical electrical specs and pinout	No functional difference; differs only in packaging format and reel quantity	Select ZLE for sample evaluation or low-volume prototyping; ZLEX preferred for automated SMT production
TS3USB30E	Single 3:1 USB 2.0/HDMI DDC+AUX switch; lacks DP support, HPD auto-priority, and CAB_DET	Limited to HDMI-only sink applications with manual port control; no DP 1.2 capability	Use only when DP compatibility and automatic HPD arbitration are not required

Compared with PI3WVR31310AZLEX, the ZLE variant offers identical performance in a different packaging format, while TS3USB30E provides basic HDMI switching but omits DP support, auto-priority logic, and CAB_DET sensing-making it unsuitable for dual-mode or robust consumer electronics designs.

FAQ

Does PI3WVR31310AZLEX support HDMI source applications?

No. The device explicitly supports HDMI-sink applications only. In HDMI mode, it functions as a 3:1 mux for connecting multiple HDMI sources to a single sink (e.g., TV or monitor). It does not support HDMI-source configurations such as transmitting from a GPU or SoC to multiple displays.

How does HPD auto-priority selection work in 1:3 demux mode?

In 1:3 demux mode (DEMUX_MUX = low), HPD1/2/3 are inputs with internal 120 kΩ pull-downs. When multiple HPDs assert, the device selects the active port based on PRI_SEL: PRI_SEL = 0 → port1 > port2 > port3; PRI_SEL = 1 → port2 > port3 > port1; PRI_SEL = M (open/VDD/2) → port3 > port1 > port2. HPD_SRC then reflects the selected port's status within <2 ms.

What is the role of CAB_1/CAB_2/CAB_3 pins?

CAB_1/2/3 indicate cable presence per port. When CAB_x = LOW, the corresponding AUX channel is enabled for DP mode; when CAB_x = HIGH, the DDC channel is enabled for HDMI mode. This allows the same physical pins to serve AUX (DP) or SDA/SCL (HDMI) depending on detected cable type and protocol mode.

Can PI3WVR31310AZLEX operate with a 2.5 V supply?

No. The device requires a nominal 3.3 V supply with operating range 3.0–3.6 V. Electrical characteristics-including R_ON, V_pass, and HPD buffer performance-are specified only for VDD = 3.3 V ±10%. Operation outside this range may cause functional failure or violate HDMI/DP electrical compliance.
