Product details
Overview
MAX9406ETJ+TG071 from Maxim Integrated is a high-speed, low-skew quad differential input to CML translator for DisplayPort-to-HDMI level shifting, featuring 350ps propagation delay, <20ps channel-to-channel skew at 2Gbps, and integrated 5V-to-3.3V DDC/HPD level shifting. It operates from 3V–3.6V over –40°C to +85°C in a 32-pin 5mm × 5mm thin QFN package.
For engineers reviewing the MAX9406ETJ+TG071 datasheet, MAX9406ETJ+TG071 pinout, MAX9406ETJ+TG071 application, or MAX9406ETJ+TG071 equivalent, this page delivers verified electrical specs, thermal characteristics, I²C-level-shifting behavior, CML output drive capability, and real-world PCB layout guidance for HDMI interface design.
Technical Context
The MAX9406ETJ+TG071 implements four independent CML translator channels with integrated 50Ω differential input terminations and biasing, supporting DP source signals up to 2Gbps while delivering 450–600mV single-ended swing into 50Ω loads referenced to VCC. Each channel maintains matched propagation paths to achieve sub-20ps inter-channel skew.
Its dual-domain level-shifting architecture separates high-speed CML translation from low-speed DDC/HPD signal conversion: SCL_SNK/SDA_SNK accept 5V I²C logic and translate to 3.3V SCL_SRC/SDA_SRC, while HPD_SNK (5V) drives HPD_SRC (3.3V) with 40–60kΩ pulldown and 2.5V–VCC output high level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 2Gbps - supports full-bandwidth HDMI 1.3/1.4 video timing without retiming or buffering. |
| Propagation Delay | 350ps typical - enables tight timing budgets in DP-to-HDMI bridge applications with minimal latency impact. |
| Channel Skew | <20ps at 2Gbps - ensures pixel-aligned differential pairs across all four lanes for stable HDMI TMDS clock recovery. |
| Differential Output Swing | 450–600mV into 50Ω to VCC - meets HDMI CML receiver input sensitivity requirements with margin. |
| DDC Level Shift | 5V ↔ 3.3V bidirectional I²C translation - allows legacy HDMI sink-side DDC communication with modern DP source controllers. |
| HPD Translation | 5V HPD_SNK to 3.3V HPD_SRC with 40–60kΩ pulldown - satisfies HDMI specification hot-plug detection voltage thresholds. |
| Supply Range | 3.0V–3.6V core supply - compatible with standard 3.3V system rails and tolerant of ±10% regulation variation. |
Pinout & Package
MAX9406ETJ+TG071 is housed in a 32-pin thin QFN package (5mm × 5mm × 0.8mm), with exposed paddle (EP) requiring connection to GND for thermal and electrical integrity. The package supports JEDEC-standard reflow and has θJA = 29°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,3,8,18,22) | Ground reference | Provides return path for all analog/digital currents; EP must be soldered to GND plane for optimal thermal performance. |
| VCC (Pins 2,7,24) | Core supply input | 3.0–3.6V power rail; requires local 0.1µF + 0.01µF ceramic bypassing per VCC pin. |
| IN_D1+/- to IN_D4+/- (Pins 25–32) | Differential DP input ports | Accept CML-compatible DP source signals; internally terminated to 40–60Ω with common-mode bias at 0–2V. |
| OUT_D1+/- to OUT_D4+/- (Pins 9–16) | Differential HDMI output ports | Drive CML outputs with 450–600mV swing into 50Ω to VCC; require matched 50Ω PCB traces. |
| SCL_SNK/SDA_SNK/HPD_SNK (Pins 19–21) | 5V DDC/HPD inputs | Interface directly with HDMI sink's 5V DDC bus and HPD line; tolerate 5.3V max input. |
| SCL_SRC/SDA_SRC/HPD_SRC (Pins 4–6) | 3.3V DDC/HPD outputs | Provide 3.3V-compatible I²C and HPD signals to DP source controller; support fast-mode (400kHz) I²C. |
| OE (Pin 17) | Output enable control | Active-low global enable for all four CML channels; high-Z state reduces ICC to 5mA while preserving DDC/HPD functionality. |
| DDC_EN (Pin 23) | DDC link gate | Enables/disables bidirectional DDC translation independently of OE; essential for dynamic DDC arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low skew CML translation | Sub-20ps channel-to-channel skew at 2Gbps ensures HDMI TMDS clock/data alignment for error-free video transmission. |
| Integrated DDC/HPD level shifting | Bidirectional 5V↔3.3V translation with dedicated SCL/SDA/HPD pins eliminates need for external level shifters in DP-to-HDMI bridges. |
| On-chip 50Ω input termination | Reduces external component count and PCB area; eliminates impedance mismatch-induced reflections on DP input lines. |
| Low-power disable mode | OE high reduces supply current to 5mA while maintaining active DDC/HPD links-critical for power-aware display hot-plug sequences. |
| Thermally optimized QFN | 32-pin thin QFN with exposed paddle achieves θJA = 29°C/W, enabling reliable operation at +85°C ambient in compact graphics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DP-to-HDMI level shifting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S016 | Single-channel HDMI ESD + level shifter; no CML translation; supports only DDC/HPD and ESD protection. | Designed for HDMI sink-side protection-not suitable for DP source-to-HDMI sink translation. | Select MAX9406ETJ+TG071 when full quad-channel CML translation and DDC/HPD shifting are required. |
| Pericom PI3HDX1204A | 4-channel HDMI redriver with equalization; no DP input support; requires 5V supply; no integrated DDC level shifting. | Targets HDMI-to-HDMI signal regeneration-not DP-to-HDMI protocol conversion. | Choose MAX9406ETJ+TG071 for native DP source interfacing where DDC/HPD voltage domain bridging is mandatory. |
Compared with TPD12S016 and PI3HDX1204A, the MAX9406ETJ+TG071 uniquely integrates quad CML translation, 5V↔3.3V DDC/HPD shifting, and ultra-low skew in a single 3.3V device-making it the only solution for direct DP-source-to-HDMI-sink interface without supplemental logic or level shifters.

FAQ
What is the maximum data rate supported by the MAX9406ETJ+TG071?
The MAX9406ETJ+TG071 supports a maximum data rate of 2Gbps per channel, validated at 2Gbps with PRBS23 pattern testing. Its 350ps propagation delay and <20ps channel-to-channel skew ensure stable HDMI TMDS timing at this rate. The device is specified for typical operation at 2Gbps, with minimum guaranteed rate of 1.85Gbps per the AC Electrical Characteristics table in the official datasheet.
Does the MAX9406ETJ+TG071 require external termination resistors on its CML outputs?
No, the MAX9406ETJ+TG071 does not require external termination on its differential inputs-those are internally terminated to 40–60Ω. However, its CML outputs must be terminated externally: each OUT_Dx+ and OUT_Dx− pair requires a 50Ω resistor to VCC (or equivalent Thevenin termination). This is explicitly required to achieve the specified 450–600mV output swing and minimize skew between channels.
How does the DDC level-shifting function work on the MAX9406ETJ+TG071?
The MAX9406ETJ+TG071 provides bidirectional 5V ↔ 3.3V level shifting for DDC lines via dedicated SCL_SNK/SDA_SNK (5V side) and SCL_SRC/SDA_SRC (3.3V side) pins. When either side is pulled low, the other follows-enabling transparent I²C communication. DDC_EN controls gating: high enables translation, low disables the DDC path while preserving HPD functionality. This allows independent control of DDC arbitration during hot-plug events.
Can the MAX9406ETJ+TG071 operate with only the DDC/HPD functions enabled and high-speed channels disabled?
Yes. Driving OE high disables all four CML channels and reduces ICC to 5mA, but the DDC and HPD translation functions remain fully operational. SCL_SRC/SDA_SRC/HPD_SRC continue to respond to activity on SCL_SNK/SDA_SNK/HPD_SNK, enabling host-side DDC reads and HPD monitoring even when video transmission is inactive-critical for low-power display enumeration and hot-plug detection.
What is the recommended PCB layout practice for the exposed paddle on the MAX9406ETJ+TG071?
The exposed paddle (EP) of the MAX9406ETJ+TG071 must be soldered to a solid GND plane. Use a landing pad matching the paddle size and place ≥4 thermal vias (0.3mm diameter) connecting the pad to an internal or bottom-layer GND polygon. This achieves the specified θJA = 29°C/W and prevents thermal throttling during sustained 2Gbps operation. Failure to connect EP to GND degrades both thermal performance and signal integrity due to floating substrate potential.
