NXP Semiconductors PTN3360BBS,518

Overview

PTN3360BBS,518 from NXP Semiconductors is a high-speed HDMI/DVI level shifter IC that converts four lanes of low-swing AC-coupled differential inputs (e.g., DisplayPort/PCIe PHY signals) to DVI v1.0- and HDMI v1.3a-compliant TMDS outputs at up to 2.5 Gbit/s per lane, with integrated 50 Ω input termination, non-inverting HPD translation, and I²C DDC level shifting between 3.3 V source and 5 V sink sides - deployed in multimedia interface bridges for multi-mode display sources.

For engineers reviewing the PTN3360BBS,518 datasheet, PTN3360BBS,518 pinout, PTN3360BBS,518 application, or PTN3360BBS,518 equivalent, this device serves as a transparent, no-re-timing, single-supply (3.3 V ±10 %) level translation solution for HDMI/DVI interconnects where back-power safety, ESD robustness (8 kV HBM), and low-power standby via OE_N/ DDC_EN control are critical design requirements.

Technical Context

The PTN3360BBS,518 implements four independent self-biasing differential input buffers compliant with DisplayPort v1.1 and PCIe v1.1 electrical specs, each driving open-drain current-steering TMDS outputs meeting HDMI v1.3a and DVI v1.0 voltage swing (500 mV typ.), rise/fall time (75–160 ps), and skew (≤10 ps intra-pair, ≤250 ps inter-pair) requirements. Its architecture avoids re-timing or state machines, enabling fully transparent signal pass-through.

It integrates three isolated level-shifting domains: (1) TMDS lanes with back-current-safe outputs and 50 Ω on-die termination; (2) DDC channel using pass-gate technology supporting 0–400 kHz I²C operation with bidirectional isolation when disabled; and (3) HPD path featuring non-inverting 5 V-to-3.3 V translation and a 200 kΩ integrated pull-down on HPD_SINK to guarantee LOW when unplugged.

Key Specifications

Pinout & Package

PTN3360BBS,518 is housed in a 48-terminal HVQFN48 package (7 × 7 × 0.85 mm, SOT619-1), with exposed thermal pad requiring PCB soldering and thermal vias for optimal thermal performance. All nine GND pins (1, 5, 12, 18, 24, 27, 31, 36, 37) and eight VDD pins (2, 11, 15, 21, 26, 33, 40, 46) must be connected for stable operation.

FAQ

What is the maximum data rate supported by PTN3360BBS,518?

PTN3360BBS,518 supports up to 2.5 Gbit/s per lane, enabling full compliance with HDMI v1.3a and DVI v1.0 specifications for resolutions including 1080p60 and UXGA. This rate corresponds to a 250 MHz character clock and is validated across temperature (−40 °C to +85 °C) and supply (3.0–3.6 V) ranges per the official NXP datasheet Rev. 02.

Does PTN3360BBS,518 require external termination resistors on its differential inputs?

No. PTN3360BBS,518 integrates 50 Ω DC termination resistors on all four IN_Dx differential input pairs, eliminating the need for external resistors. This simplifies layout, reduces component count, and ensures consistent input impedance matching - critical for maintaining signal integrity in high-speed AC-coupled interfaces.

How does PTN3360BBS,518 handle hot-plug detection (HPD) signal translation?

PTN3360BBS,518 provides non-inverting HPD level shifting from 0–5 V on HPD_SINK (pin 30) to 0–3.3 V on HPD_SOURCE (pin 7), with an integrated 200 kΩ pull-down resistor on HPD_SINK to guarantee LOW when no display is connected. The HPD_SOURCE output follows HPD_SINK state regardless of OE_N or DDC_EN status.

Can PTN3360BBS,518 operate without the external REXT resistor?

Yes. PTN3360BBS,518 can operate with REXT (pin 6) left open, tied to VDD or GND, or connected via a resistor <10 kΩ. However, using the recommended 10 kΩ ±1 % resistor to GND ensures best accuracy for output voltage swing, rise/fall times, and VOL/VOL stability over voltage and temperature - especially critical in high-fidelity video links.

Is PTN3360BBS,518 compatible with both HDMI and DVI sinks simultaneously?

Yes. PTN3360BBS,518's TMDS outputs meet the electrical specifications of both HDMI v1.3a and DVI v1.0, including voltage swing (500 mV typ.), termination (50 Ω to 3.3 V), and timing (rise/fall ≤160 ps). Its DDC and HPD interfaces also support bidirectional communication with either sink type - enabling single-design reuse across HDMI and DVI endpoints.
