Product details
Overview
PTN3300BHF2,518 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 designs supporting HDMI, DVI, and DisplayPort on shared I/O pins.
For engineers reviewing the PTN3300BHF2,518 datasheet, PTN3300BHF2,518 pinout, PTN3300BHF2,518 application, or PTN3300BHF2,518 equivalent, key selection criteria include TMDS lane speed (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 HWQFN48 thermal-enhanced package compatibility.
Technical Context
The PTN3300BHF2,518 implements transparent, re-timing-free level translation across four independent high-speed lanes using self-biasing differential receivers with integrated 50 Ω termination and open-drain current-steering transmitters compliant with DVI v1.0 and HDMI v1.3a electrical specifications. Its architecture supports simultaneous AC-coupled input (PCIe/DP signaling) and DC-coupled TMDS output into 50 Ω to 3.3 V.
It integrates three independent level-shifting subsystems: (1) TMDS path with OE_N-controlled enable/disable and standby mode triggered by HPD_SINK = LOW; (2) DDC path using bidirectional pass gates with DDC_EN gating and 0–400 kHz bandwidth; (3) HPD path with non-inverting 5 V → 3.3 V translation and internal 200 kΩ pull-down on HPD_SINK. All sink-side terminals feature back-drive protection.

Pinout & Package
PTN3300BHF2,518 uses the HWQFN48 package (SOT1074-1): 7 × 7 × 0.65 mm body, no leads, 48 terminals, exposed thermal pad, resin-based construction. All GND pins (1, 5, 12, 18, 24, 27, 31, 36, 37, 43) and the exposed pad must be soldered to PCB ground for thermal, electrical, and functional integrity.

| OE_N (pin 25) DDC_EN (pin 32) |
Functional enable controls | OE_N (active LOW) disables TMDS lanes only; DDC_EN (active HIGH) enables/disables DDC path independently |

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 logic, and inverted HPD_SOURCE_N output | Required for HDMI-compliant dongles needing active DDC arbitration and dongle presence signaling | Select PTN3301HN/C,518 when HDMI dongle detection or buffered DDC is mandatory; PTN3300BHF2,518 suffices for basic level shifting |
| SN75DP130RGZR | Single-chip DisplayPort-to-HDMI bridge with embedded SerDes, re-timing, and HDCP support; requires configuration | Used where protocol conversion (DP packet → TMDS stream), HDCP, or embedded audio is needed | Choose SN75DP130RGZR for full protocol bridging; PTN3300BHF2,518 is preferred for transparent, low-latency, no-software level shifting |

FAQ
What is the maximum data rate supported by PTN3300BHF2,518 per TMDS lane?
The PTN3300BHF2,518 supports up to 2.25 Gbit/s per lane, corresponding to a 225 MHz character clock. This meets HDMI v1.3a and DVI v1.0 electrical specifications and enables resolutions including 1080p60 and WUXGA. The device maintains specified jitter (≤7.4 ps), skew (≤250 ps interpair), and rise/fall times (75–180 ps) at this rate.
Does PTN3300BHF2,518 require external termination resistors on its differential inputs?
No, PTN3300BHF2,518 integrates 50 Ω termination resistors on all IN_Dx+ and IN_Dx− inputs. These self-biasing differential inputs are designed for AC-coupled low-swing signaling (e.g., PCIe/DisplayPort) and do not require external termination. External AC coupling capacitors remain mandatory.
How does PTN3300BHF2,518 handle Hot Plug Detect (HPD) signal translation?
PTN3300BHF2,518 performs non-inverting level shifting of HPD from 5 V (sink side, HPD_SINK) to 3.3 V (source side, HPD_SOURCE). It includes an integrated 200 kΩ pull-down on HPD_SINK to guarantee LOW when no display is connected, automatically triggering standby mode to minimize power consumption.
What is the purpose of the REXT pin on PTN3300BHF2,518?
The REXT pin (pin 6) sets the current reference for the TMDS differential outputs. Connecting a 10 kΩ ±1 % resistor from REXT to GND ensures optimal output voltage swing accuracy (VOL, VOH), differential swing, and rise/fall time stability over voltage and temperature. Omitting it degrades accuracy but maintains basic functionality.
Is PTN3300BHF2,518 compatible with DisplayPort sources?
Yes, PTN3300BHF2,518 accepts low-swing AC-coupled differential inputs compliant with DisplayPort v1.1 and PCI Express v1.1 standards. It translates these signals to DVI/HDMI-compliant TMDS outputs, enabling DisplayPort sources to drive HDMI or DVI sinks without protocol conversion-only physical layer level shifting.
