Product details
Overview
PTN3300AHF2,518 from NXP Semiconductors is a DVI/HDMI level shifter IC that converts four lanes of 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, inverting 1.1 V HPD output, and bidirectional DDC level shifting between 3.3 V source and 5 V sink sides. It operates from a single 3.3 V supply and supports power-saving standby mode via HPD_SINK or OE_N.
For engineers reviewing the PTN3300AHF2,518 datasheet, PTN3300AHF2,518 pinout, PTN3300AHF2,518 application, or PTN3300AHF2,518 equivalent, key selection criteria include TMDS lane speed compliance (2.25 Gbit/s), back-current-safe sink-side terminals, REXT-referenced output accuracy, HPD inversion logic, and HWQFN48 package thermal performance for HDMI/DVI interface bridging in multi-mode display sources.
Technical Context
The PTN3300AHF2,518 implements transparent, non-re-timing level translation across three signal domains: four high-speed TMDS lanes using self-biasing differential inputs with integrated 50 Ω termination and open-drain current-steering outputs compliant to DVI v1.0 and HDMI v1.3a; a single-ended inverting HPD buffer translating 0 V/5 V sink-side logic to 0 V/1.1 V source-side logic; and bidirectional DDC pass-gate level shifting supporting I²C up to 400 kHz with DDC_EN control and back-power safety.
Its enable architecture separates control domains: OE_N disables only TMDS lanes (high-impedance IN_Dx/OUT_Dx), DDC_EN isolates only SCL/SDA paths, and HPD_SINK automatically places both TMDS and DDC into standby when LOW-triggering <50 µA quiescent current. All sink-side pins (HPD_SINK, SCL_SINK, SDA_SINK, OUT_Dx) are back-current safe, preventing reverse current flow when the sink is powered but the PTN3300AHF2,518 is unpowered.

Pinout & Package
PTN3300AHF2,518 uses the HWQFN48 package (SOT1074-1): 7 mm × 7 mm × 0.65 mm body, no leads, 48 terminals, exposed thermal pad, leadframe-based construction with visible terminals at package edge. GND pins (1, 5, 12, 18, 24, 27, 31, 36, 37, 43) and the exposed center pad must be soldered to PCB ground for electrical integrity and thermal dissipation.
| 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 | Accept low-swing AC-coupled PCIe/DP signals; 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 current-steering outputs | DVI/HDMI-compliant open-drain outputs; require external 50 Ω to 3.3 V termination |
| HPD_SINK (pin 30) | 5 V CMOS input | Detects sink presence; internal 200 kΩ pull-down ensures LOW when unplugged; triggers standby |
| HPD_SOURCE_N (pin 7) | 1.1 V CMOS output | Inverted HPD logic level-shifted to source-side 1.1 V rail; active regardless of standby state |
| SCL_SOURCE / SDA_SOURCE (pins 9, 8) SCL_SINK / SDA_SINK (pins 28, 29) | DDC I²C pass-gate I/O | Bidirectional level shifting between 3.3 V source and 5 V sink; enabled only when DDC_EN = HIGH and HPD_SINK = HIGH |
| OE_N (pin 25) | 3.3 V CMOS enable input | Active-low control for TMDS lanes only; disables IN_Dx termination and OUT_Dx drive when HIGH |
| DDC_EN (pin 32) | 3.3 V CMOS enable input | Active-high control for DDC path only; must toggle only during I²C bus idle periods |
| REXT (pin 6) | Analog current reference | Connect 10 kΩ ±1 % resistor to GND for accurate output voltage swing; open-circuit allowed with reduced accuracy |

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 circuitry, and non-inverting HPD output | Required for HDMI-compliant dongles needing active EDID emulation or dongle-detection handshake | Select PTN3301HN/C,518 when HDMI-specific features like dongle detect or buffered DDC are mandatory |
| SN75DP130RGZT | Single-lane DisplayPort-to-HDMI converter with integrated retimer and HDCP support; requires configuration via I²C | Targets DP source → HDMI sink conversion with HDCP compliance and jitter cleanup, not transparent level shifting | Select SN75DP130RGZT when signal regeneration, HDCP, or DisplayPort-native input is required instead of PCIe/DP PHY reuse |

FAQ
What is the maximum data rate supported by PTN3300AHF2,518 per TMDS lane?
The PTN3300AHF2,518 supports up to 2.25 Gbit/s per TMDS lane, corresponding to a 225 MHz character clock required for HDMI 1.3a and DVI v1.0 high-definition video transmission. This rate is validated under recommended operating conditions with proper AC coupling and 50 Ω termination on both input and output sides. The PTN3300AHF2,518 achieves this without re-timing, preserving signal integrity across the level shift.
Does PTN3300AHF2,518 require an external resistor on the REXT pin?
A 10 kΩ ±1 % resistor from REXT (pin 6) to GND is recommended for optimal output voltage swing accuracy, rise/fall time, and VOL/VOL consistency across temperature and voltage. While the PTN3300AHF2,518 functions without it-allowing REXT to be left open, tied to VDD, or grounded-the differential output parameters degrade in accuracy. For production HDMI/DVI interfaces where TMDS signal margin is critical, the external resistor is strongly advised for the PTN3300AHF2,518.
How does PTN3300AHF2,518 handle hot-plug detection when no display is connected?
The PTN3300AHF2,518 integrates a 200 kΩ pull-down resistor on HPD_SINK (pin 30), ensuring a reliable LOW state when no display is plugged in. This automatically places the PTN3300AHF2,518 into standby mode, reducing supply current to ≤50 µA. Simultaneously, HPD_SOURCE_N (pin 7) outputs a HIGH (1.1 V) signal-logic-inverted from the sink-side LOW-enabling the source to detect disconnection without external components. This behavior is guaranteed across −40 °C to +85 °C ambient.
Can PTN3300AHF2,518 be used with DisplayPort sources?
Yes, the PTN3300AHF2,518 is explicitly designed for use with DisplayPort-compliant sources: its IN_Dx inputs meet DisplayPort v1.1 and PCI Express v1.1 electrical specifications, including low-swing AC-coupled differential signaling and integrated 50 Ω termination. When paired with a DP PHY configured for HDMI/DVI coding, the PTN3300AHF2,518 translates those signals to TMDS-compliant outputs-enabling a single multi-mode source to drive HDMI or DVI sinks without redesigning the PHY layer.
Is PTN3300AHF2,518 pin-compatible with PTN3300AHF,518?
No, PTN3300AHF2,518 and PTN3300AHF,518 use different HWQFN packages: PTN3300AHF2,518 is in HWQFN48 (SOT1074-1, 7 × 7 × 0.65 mm), while PTN3300AHF,518 is in HWQFN48R (SOT1031-2, 7 × 7 × 0.7 mm). Though both have 48 pins and identical pin functions, the mechanical dimensions and thermal pad layout differ. PCB layout is not interchangeable; board redesign is required when migrating between these variants of PTN3300AHF2,518 and PTN3300AHF,518.
