Product details
Overview
PI3HDX612ZLDEX from Diodes Incorporated is a 6Gbps HDMI 2.0 1:2 active signal duplicator IC designed for high-bandwidth video fanout in source-side applications. It supports 4K@60Hz resolution, features quad-level CTLE equalization (up to 8.9dB at 3GHz), programmable flat gain (−3.5dB to −0.5dB), and output swing control (800–1200mVppd), all configurable via pin strap or I²C. Used in PC graphics outputs driving dual HDMI displays.
For engineers reviewing the PI3HDX612ZLDEX datasheet, PI3HDX612ZLDEX pinout, PI3HDX612ZLDEX application, or PI3HDX612ZLDEX equivalent, key selection criteria include HDMI 2.0 channel count (3 data + 1 clock lanes ×2 outputs), CML I/O compatibility, 3.3V single-supply operation, −40°C to +70°C industrial temperature range, and ESD robustness (2kV HBM).
Technical Context
The PI3HDX612ZLDEX implements three independent differential input channels (RX0/1/2+,− and CLK+,−) feeding two fully replicated output banks (A/B), each with dedicated CML drivers for data (A0/B0–A2/B2) and clock (ACLK/BCLK). Its CTLE equalizers operate across 100MHz–3GHz with seven selectable boost profiles, compensating channel loss up to 15dB.
Control logic supports dual-mode configuration: pin-strapped mode (using EQ1/EQ2/RSVD, SF, MS) for static setup, and I²C slave mode (7-bit address, 100kHz) for dynamic per-channel power-down, equalizer tuning, and swing/gain adjustment. Power-down (PD pin) places all I/Os in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 6Gbps per lane - enables HDMI 2.0 4K@60Hz (4-lane TMDS) transmission without compression. |
| Equalization Range | 0.5–8.9dB at 3GHz - compensates PCB trace loss up to ~15dB over 15cm FR4 at 3GHz. |
| Output Swing | 800–1200mVppd - matches HDMI 2.0 receiver sensitivity while minimizing EMI via adjustable amplitude. |
| Flat Gain | −3.5dB to −0.5dB - maintains signal integrity across frequency by flattening CML driver response. |
| Input Return Loss | −21dB (diff, 10MHz–3GHz) - ensures minimal reflection-induced jitter on source-side HDMI inputs. |
| Supply Voltage | 3.0–3.6V - operates from standard 3.3V rail with ±0.3V tolerance; no auxiliary supplies required. |
| ESD Protection | ±2kV HBM - protects HDMI I/O pins against handling and system-level electrostatic discharge events. |
Pinout & Package
Package: 40-pin TQFN (ZLD), 3 mm × 6 mm, 0.4 mm pitch, exposed thermal pad (EP) for enhanced thermal dissipation in high-power active-redriver operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RX0+/RX0−, RX1+/RX1−, RX2+/RX2−, CLK+/CLK− | HDMI 2.0 TMDS input receivers | CML differential inputs with internal 50Ω termination to VCC; accept 1.2Vppd signals compliant with HDMI spec. |
| A0TX+/A0TX−, B0TX+/B0TX−, ..., ACLK+/ACLK−, BCLK+/BCLK− | Dual-channel HDMI output drivers | CML outputs with internal 50Ω pull-up; deliver programmable swing (800–1200mVppd) to two independent display sinks. |
| EQ1/EQ2/RSVD, SF, MS, PD | Configuration & control inputs | 4-level logic pins (with internal 100kΩ pull-up/200kΩ pull-down) set equalization, swing, flat gain, and mode; PD enables full-chip power-down. |
| SCL/SDA | I²C interface | Standard-mode (100kHz) slave interface for runtime register access; supports 7-bit address strapping via AD10/AD32/AD54. |
| VCC (pins 3,9,12,23,32), GND (18,37), EP | Power delivery network | Five VCC pins reduce IR drop; exposed pad lowers θJA to 17.9°C/W for sustained 1.66W active power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 1:2 HDMI 2.0 fanout architecture | Replicates full 4-lane TMDS + clock path to two independent displays without signal degradation or timing skew. |
| Quad-level CTLE equalization | Seven discrete boost settings (0.5–8.9dB at 3GHz) compensate varying PCB trace lengths and loss profiles. |
| Pin-strapped + I²C dual-mode control | Enables factory-set static configuration (no firmware) or dynamic runtime tuning in embedded systems. |
| Per-channel power-down via I²C | Allows selective disabling of individual output channels (A0/B0–A2/B2) to reduce power in multi-display standby states. |
| Integrated 3.3V CML I/O | Eliminates external level shifters; compatible with GPU HDMI transmitters and display receiver inputs. |
Applications
| PC Graphics Multi-Display Output | Digital Signage Video Distribution |
|---|---|
|
Use Scenario: A discrete GPU outputs HDMI 2.0 to drive two 4K monitors simultaneously via a single port. IC Role / Device Role / Timing Role: Active signal duplicator placed at source side; regenerates and fans out TMDS lanes and clock to two independent HDMI receivers. Use Value: Maintains 6Gbps signal integrity across both paths, enabling synchronized 4K@60Hz on dual displays without pixel drop or color banding. |
Use Scenario: A media player feeds identical 4K content to multiple wall-mounted displays in retail or transportation hubs. IC Role / Device Role / Timing Role: Central HDMI duplication node in digital signage controller; splits one source stream into parallel outputs with matched latency. Use Value: Eliminates need for separate source hardware per display; ensures identical frame timing and color fidelity across all screens. |
| Multi-Screen Splicing Systems | HDMI Display Peripheral Boxes |
|
Use Scenario: Video wall controller combines four 1080p inputs into a single 4K canvas, requiring duplicated HDMI outputs for adjacent panels. IC Role / Device Role / Timing Role: Lane-level signal repeater within splicing engine; duplicates specific TMDS lanes to adjacent display modules. Use Value: Enables precise pixel-aligned tiling by preserving sub-nanosecond inter-lane skew between duplicated outputs. |
Use Scenario: Compact HDMI switcher or splitter box routes one source to two TVs/projectors with EDID management. IC Role / Device Role / Timing Role: Core redriver in consumer/pro AV enclosure; restores signal amplitude and equalizes channel loss after cable attenuation. Use Value: Supports long HDMI cables (up to 15m passive) while maintaining HDCP 2.2 compliance and stable hot-plug detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI 2.0 signal duplication applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TDP1420IRHBT | Single-output HDMI 2.0 redriver (1:1); no built-in fanout; requires external multiplexer for 1:2. | Limited to point-to-point regeneration; cannot replace PI3HDX612ZLDEX without added logic and layout complexity. | Select only when duplication is handled upstream and only signal conditioning is needed. |
| Maxim MAX9278AETL+ | GMSL2 serializer with HDMI bridge; supports 1:2 via external FPGA; not pin-compatible; requires 1.8V/3.3V dual supply. | Targets automotive camera links; lacks native HDMI 2.0 timing compliance and DDC/HPD pass-through. | Choose only for GMSL-based systems needing HDMI translation-not for direct HDMI duplication. |
Compared with TI TDP1420IRHBT and Maxim MAX9278AETL+, the PI3HDX612ZLDEX uniquely integrates full 1:2 HDMI 2.0 fanout, CTLE equalization, and dual-mode control in a single 40-pin TQFN-reducing BOM count, PCB area, and firmware overhead versus multi-chip alternatives.

FAQ
What is the maximum supported HDMI resolution and refresh rate?
The PI3HDX612ZLDEX supports HDMI 2.0 with a 6Gbps per-lane data rate, enabling 4K resolution at 60Hz (3840×2160@60Hz) or 2K at 144Hz. This is achieved using all four TMDS data lanes plus the clock lane, with full compliance to HDMI 2.0 electrical specifications including jitter tolerance and eye diagram requirements.
Does the device support DDC and HPD pass-through for display enumeration?
Yes - the PI3HDX612ZLDEX does not terminate or modify DDC (I²C) or HPD signals. These signals are routed directly from source to both output ports (DDC1/HPD1 and DDC2/HPD2), preserving EDID communication and hot-plug detection functionality required for automatic display detection and configuration.
Can equalization and output swing be adjusted independently per output channel?
No - EQ1/EQ2 and SF pins configure equalization and swing/flat gain globally for both A and B output banks. However, I²C register access (via BYTE 2–6) allows per-channel power-down and per-channel selection of EQ<2:0>, FG1/FG0, and SW1/SW0 - enabling independent tuning of equalization profile, flat gain, and swing on each output bank.
What thermal management is required for continuous 4K@60Hz operation?
At full 4K@60Hz operation, the PI3HDX612ZLDEX dissipates ~1.66W. With its 40-pin TQFN (ZLD) package and θJA = 17.9°C/W, a minimum 150mm² copper pour connected to the exposed pad is required to maintain junction temperature ≤105°C at +70°C ambient. Use mesh stencil for EP soldering to ensure void-free thermal interface.
