Product details
Overview
PTN3300BHF,518 from NXP Semiconductors is a 4-lane DVI/HDMI level shifter IC that converts low-swing AC-coupled differential inputs (DisplayPort/PCIe compliant) to TMDS-compliant open-drain current-steering outputs at up to 2.25 Gbit/s per lane, with integrated 50 Ω input termination, 3.3 V single-supply operation, and back-current-safe sink-side I/O. It enables multi-mode display source devices to support HDMI/DVI while minimizing I/O pin count.
For engineers reviewing the PTN3300BHF,518 datasheet, PTN3300BHF,518 pinout, PTN3300BHF,518 application, or PTN3300BHF,518 equivalent, key selection considerations include TMDS lane speed compliance (2.25 Gbit/s), HPD non-inverting level shift (5 V → 3.3 V), DDC pass-gate isolation (0–400 kHz), REXT-referenced output accuracy, and HWQFN48R thermal pad layout requirements.
Technical Context
The PTN3300BHF,518 implements four independent self-biasing differential input buffers with integrated 50 Ω termination, each driving an open-drain current-steering TMDS output compliant with DVI v1.0 and HDMI v1.3a electrical specifications. Its differential path operates transparently-no retiming, no state machines, no latching-ensuring zero latency signal translation.
It integrates three isolated level-shifting domains: HPD (non-inverting 5 V ↔ 3.3 V), DDC (bidirectional pass-gate I²C channel supporting 0–400 kHz with DDC_EN control), and TMDS (AC-coupled input to DC-coupled 50 Ω-terminated output). Power management uses HPD_SINK-driven standby mode and OE_N-controlled TMDS disablement, achieving ≤2 µA standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Lane count | 4 independent high-speed differential lanes for TMDS clock/data |
| Max data rate | 2.25 Gbit/s per lane (225 MHz character clock); meets HDMI 1.3a timing budget |
| Supply voltage | 3.3 V ±10 %; consumes 35 mA typical in active mode (120 mW) |
| Differential input | Self-biasing, AC-coupled, 50 Ω terminated; compatible with PCIe v1.1/DP v1.1 signaling |
| Output compliance | Open-drain current-steering TMDS outputs meeting DVI v1.0 and HDMI v1.3a sink-side specs |
| DDC support | Pass-gate level shifter for SCL/SDA; 0–400 kHz operation; DDC_EN enables/disables isolation |
| HPD function | Non-inverting level shift: 0–5 V sink input → 0–3.3 V source output; includes 200 kΩ pull-down |
Pinout & Package
The PTN3300BHF,518 is housed in a 7 × 7 × 0.7 mm HWQFN48R (SOT1031-2) package with exposed thermal pad requiring solder connection and thermal vias for optimal performance. All 10 GND pins and the center pad must be connected to system ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_D1+ / IN_D1− IN_D2+ / IN_D2− IN_D3+ / IN_D3− IN_D4+ / IN_D4− | Self-biasing differential inputs | AC-coupled low-swing inputs accepting PCIe/DP-style signaling; each pair internally terminated to 50 Ω when OE_N = LOW |
| OUT_D1+ / OUT_D1− OUT_D2+ / OUT_D2− OUT_D3+ / OUT_D3− OUT_D4+ / OUT_D4− | TMDS differential outputs | Open-drain current-steering outputs compliant with DVI/HDMI sink termination (50 Ω to 3.3 V); phase-aligned with respective inputs |
| HPD_SINK (pin 30) HPD_SOURCE (pin 7) | Hot Plug Detect interface | 5 V CMOS input detects display connection; 3.3 V CMOS output provides non-inverted level-shifted signal; internal 200 kΩ pull-down ensures LOW when unplugged |
| SCL_SOURCE (9) SDA_SOURCE (8) SCL_SINK (28) SDA_SINK (29) | DDC I²C pass-gate channels | Bidirectional level-shifting I²C lines using pass-gate architecture; enabled only when DDC_EN = HIGH and HPD_SINK = HIGH |
| OE_N (pin 25) DDC_EN (pin 32) | Functional enable controls | OE_N (active LOW) disables TMDS lanes only; DDC_EN (active HIGH) isolates DDC channel; both support independent power gating |
| REXT (pin 6) | Analog current reference | Connect 10 kΩ ±1 % resistor to GND to calibrate output current accuracy; open-circuit or tie-to-rail operation degrades VOL/VOL swing accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Transparent TMDS translation | No re-timing, no firmware, no state machines-zero-latency signal pass-through ideal for real-time video paths |
| Back-current-safe sink I/O | Prevents reverse current flow from powered display into unpowered PTN3300BHF,518; protects source-side power rails during hot-plug scenarios |
| Multi-domain power gating | Independent control via OE_N (TMDS), DDC_EN (I²C), and HPD_SINK (system-wide standby) enables granular power optimization |
| Integrated 50 Ω input termination | Eliminates external resistors on AC-coupled differential inputs; reduces BOM count and PCB area in high-density display interfaces |
| DDC pass-gate isolation | Enables/disable DDC channel without bus hang risk when toggled only during I²C idle periods; supports robust EDID communication |

Use Value: Achieves ultra-low power consumption without external microcontroller intervention; simplifies power sequencing design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DVI/HDMI level shifting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTN3301HN/C,518 | Includes active DDC buffering (not pass-gate), HDMI dongle detect, and enhanced ESD (4 kV HBM) | Required for HDMI-only systems needing dongle detection or higher reliability in noisy environments | Select PTN3301HN/C,518 if active DDC drive and HDMI-specific features are mandatory; PTN3300BHF,518 suffices for standard DVI/HDMI with passive DDC |
| SN75DP130RGZT | Single-chip DisplayPort-to-HDMI converter with integrated retimer; supports HDCP; requires configuration via I²C | Used when DisplayPort source must drive HDMI sink with protocol translation-not pure level shifting | Choose SN75DP130RGZT only when DP-to-HDMI protocol conversion and HDCP are needed; PTN3300BHF,518 is strictly electrical level translation |
Compared with PTN3300BHF,518, PTN3301HN/C,518 adds active DDC drive and HDMI dongle detection but increases complexity and cost, while SN75DP130RGZT provides full protocol conversion at the expense of transparency and added configuration overhead-neither offers pin compatibility or identical functional scope.

FAQ
What is the maximum data rate supported by the PTN3300BHF,518?
The PTN3300BHF,518 supports up to 2.25 Gbit/s per lane, corresponding to a 225 MHz character clock, fully compliant with HDMI v1.3a and DVI v1.0 TMDS timing requirements. This rate is validated across all four differential lanes simultaneously under recommended operating conditions (3.3 V ±10 %, −40 °C to +85 °C).
Does the PTN3300BHF,518 require external termination resistors on its differential inputs?
No, the PTN3300BHF,518 integrates 50 Ω termination resistors for all four differential input pairs (IN_D1± through IN_D4±), eliminating the need for external components. These terminations are enabled only when OE_N is LOW; they are disabled in high-impedance mode when OE_N is HIGH.
How does the PTN3300BHF,518 handle Hot Plug Detect (HPD) signaling?
The PTN3300BHF,518 provides non-inverting HPD level shifting: HPD_SINK (0–5 V input) drives HPD_SOURCE (0–3.3 V output) with propagation delay ≤200 ns. An integrated 200 kΩ pull-down on HPD_SINK guarantees LOW when no display is connected, triggering automatic standby mode to minimize power consumption.
What is the purpose of the REXT pin on the PTN3300BHF,518?
The REXT pin (pin 6) sets the output current reference for the TMDS differential drivers. Connecting a 10 kΩ ±1 % resistor from REXT to GND ensures optimal accuracy of VOL, differential swing, and rise/fall times. Omitting this resistor degrades output voltage accuracy over temperature and supply variation but maintains basic functionality.
Is the PTN3300BHF,518 compatible with DisplayPort sources?
Yes-the PTN3300BHF,518 differential inputs are explicitly designed to accept low-swing AC-coupled differential signals compliant with DisplayPort v1.1 and PCI Express v1.1 electrical specifications. It translates these signals to DVI/HDMI-compliant TMDS outputs without protocol interpretation or retiming.
