Product details
Overview
PTN3363BSMP from NXP Semiconductors is a low-power HDMI/DVI level shifter IC that converts four lanes of low-swing AC-coupled differential inputs to DVI v1.0 and HDMI v1.4b–compliant TMDS outputs at up to 3.4 Gbit/s per lane, supports 4K × 2K/3D video, integrates active DDC buffering with I²C-level shifting (3.3 V ↔ 5 V), and provides HPD voltage translation (5 V sink → 3.3 V source) for DisplayPort++ adapter applications.
For engineers reviewing the PTN3363BSMP datasheet, PTN3363BSMP pinout, PTN3363BSMP application, or PTN3363BSMP equivalent, key selection considerations include its 32-pin HVQFN package, programmable equalization (0–6 dB), HIZ_EN-controlled input termination, REXT-based current reference accuracy, and back-current-safe sink-side I/Os essential for robust hot-plug and redriver implementations.
Technical Context
The PTN3363BSMP implements transparent, non-retiming level translation across three signal domains: four high-speed TMDS lanes (IN_Dx → OUT_Dx) with self-biasing 50 Ω inputs and open-drain current-steering outputs; a bidirectional DDC channel (SCL/SDA) using active I²C-bus buffer architecture with rise-time acceleration on sink-side ports; and a unidirectional HPD level shifter with integrated 200 kΩ pull-down on HPD_SINK.
Its functional modes are controlled by OE_N (TMDS enable), DDC_EN (DDC enable), HIZ_EN (input termination mode), EQ0/EQ1 (4-level equalization), and DDET (HDMI dongle detection enable), all operating independently without state machines or clocked logic - ensuring deterministic latency and zero configuration overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max data rate | 3.4 Gbit/s per lane - supports HDMI v1.4b 36-bit deep color, 4K × 2K, and 3D video transport. |
| Supply voltage | 2.8 V to 3.6 V - single 3.3 V ±10 % rail powers full functionality with 72 mW typical consumption. |
| Input interface | Four self-biasing AC-coupled differential pairs (IN_D1± to IN_D4±) compliant with DisplayPort v1.2a/PCIe v1.1 electrical specs. |
| Output interface | Four open-drain current-steering TMDS outputs (OUT_D1± to OUT_D4±) compliant with DVI v1.0/HDMI v1.4b sink requirements. |
| DDC capability | I²C-bus level shifter supporting 400 kHz clock, 3.3 V ↔ 5 V translation, rise-time acceleration on sink-side SCL/SDA, and slave ROM for HDMI dongle detection. |
| HPD translation | Non-inverting level shift from 0–5 V (sink) to 0–3.3 V (source) with integrated 200 kΩ pull-down on HPD_SINK for reliable plug-detection. |
| Equalization | Programmable 0 dB / 2 dB / 4 dB / 6 dB via EQ0/EQ1 binary inputs - compensates channel loss in long-cable or multi-adapter paths. |
Pinout & Package
PTN3363BSMP is housed in a 5 mm × 5 mm × 0.85 mm HVQFN32 package (SOT617-3) with an exposed thermal pad requiring solder connection to system ground for thermal, electrical, and mechanical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_D1± to IN_D4± (pins 25–32) | Self-biasing differential inputs | Accept low-swing AC-coupled DP/HDMI-coded signals; internal 50 Ω termination enabled when HIZ_EN = LOW. |
| OUT_D1± to OUT_D4± (pins 9–16) | TMDS current-steering outputs | Drive DVI/HDMI-compliant DC-coupled differential loads terminated to 50 Ω @ 3.3 V; back-current safe when unpowered. |
| HPD_SINK (pin 21), HPD_SOURCE (pin 5) | Hot Plug Detect level shifter | Translates sink-side 0–5 V HPD to source-side 0–3.3 V output; HPD_SINK includes 200 kΩ pull-down for 'no display' detection. |

| OE_N (pin 17), DDC_EN (pin 22), HIZ_EN (pin 24) | Functional control inputs | Independent enable/disable of TMDS path, DDC path, and input termination mode - no interlock or sequencing required. |
| REXT (pin 4), EQ0 (pin 8), EQ1 (pin 2), DDET (pin 3) | Analog/feature configuration | REXT sets output current accuracy (12.4 kΩ recommended); EQ0/EQ1 select equalization; DDET enables HDMI dongle detection ROM. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DVI level shifting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S016 | Single-lane HDMI level shifter with integrated ESD protection; lacks DDC buffer, HPD translation, and equalization; max 3.0 Gbit/s. | Targeted at cost-sensitive, single-port HDMI add-ons - not suitable for 4-lane DP++ or 4K/3D use cases. | Select only for basic HDMI output where DDC isolation, multi-lane support, or 3.4 Gbit/s operation are unnecessary. |
| Pericom PI3HDX1204A | 4-lane HDMI redriver with fixed 6 dB equalization; no DDC/HPD functions; requires external level-shifting for control signals. | Designed for native HDMI redriver applications only - cannot translate DP++ source signals or manage DDC/HPD handshakes autonomously. | Choose when interfacing HDMI-only sources and sinks; requires companion logic for HPD/DDC management. |
Compared with TPD12S016 and PI3HDX1204A, PTN3363BSMP uniquely integrates full DP++ level shifting, active DDC buffering, HPD translation, and programmable equalization in one HVQFN32 device - eliminating need for supplemental ICs in adapter and docking designs.

FAQ
What is the maximum data rate supported by PTN3363BSMP per TMDS lane?
PTN3363BSMP supports up to 3.4 Gbit/s per lane, enabling transmission of HDMI v1.4b 36-bit deep color, 4K × 2K resolution, and 3D video formats. This corresponds to a 340 MHz TMDS clock frequency and is validated per DVI v1.0 and HDMI v1.4b electrical compliance requirements.
Does PTN3363BSMP require configuration or firmware to operate?
No, PTN3363BSMP operates transparently with no retiming, no state machines, and no software configuration. All functionality - including level shifting, equalization, DDC buffering, and HPD translation - is controlled by hardware pins (OE_N, DDC_EN, EQ0/EQ1, HIZ_EN, DDET). The PTN3363BSMP requires no initialization sequence or driver support.
How does PTN3363BSMP handle back-current protection when the sink is powered but PTN3363BSMP is not?
PTN3363BSMP provides back-current-safe design on all sink-side terminals - TMDS outputs (OUT_Dx), DDC I/Os (SCL_SINK/SDA_SINK), and HPD_SINK. When unpowered, it sinks less than negligible leakage current and blocks reverse current flow from the sink into its VDD rail or upstream source, preventing damage or unintended power-up.
What is the purpose of the REXT pin on PTN3363BSMP, and what resistor value is recommended?
The REXT pin (pin 4) sets the current reference for PTN3363BSMP's TMDS output drivers. For optimal output voltage swing accuracy across voltage and temperature, a 12.4 kΩ ±1 % resistor between REXT and GND is recommended. Direct connection to GND or VDD is allowed but reduces accuracy of VOL, differential swing, and edge timing.
Can PTN3363BSMP be used in both DP++ adapter and native HDMI redriver configurations?
Yes - PTN3363BSMP supports both use cases. In DP++ mode, HIZ_EN = LOW enables internal 50 Ω input termination for low-swing AC-coupled DP signals. In native HDMI redriver mode, HIZ_EN = HIGH places inputs in high-Z, allowing external 50 Ω termination - confirmed in Figure 2 and Section 7.1.4 of the datasheet.
