Product details
Overview
PTN3360ABS,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. It provides inverting HPD level shifting (5 V sink → 1.1 V source), bidirectional DDC I²C level shifting (3.3 V ↔ 5 V), and integrated 50 Ω input termination. It enables multi-mode display source chipsets in graphics controllers and embedded video interfaces.
For engineers reviewing the PTN3360ABS,518 datasheet, PTN3360ABS,518 pinout, PTN3360ABS,518 application, or PTN3360ABS,518 equivalent, key selection considerations include TMDS lane speed compliance (2.5 Gbit/s), HPD inversion behavior, back-power-safe sink-side terminals, REXT-referenced output current accuracy, and HVQFN48 thermal pad layout requirements.
Technical Context
The PTN3360ABS,518 implements transparent, non-retiming level translation across three signal domains: four high-speed TMDS lanes with self-biasing 50 Ω differential inputs and open-drain current-steering outputs; a pass-gate-based DDC channel supporting 0–400 kHz I²C operation with enable-controlled isolation; and an inverting HPD buffer with integrated 200 kΩ pull-down on HPD_SINK. All sink-side pins (TMDS outputs, DDC I/Os, HPD_SINK) feature back-drive protection to block current flow when unpowered.
Its functional architecture separates control domains: OE_N exclusively enables/disables TMDS path termination and output drive (not affecting HPD or DDC), while DDC_EN independently gates DDC signal pass-through. The REXT pin sets output current reference via external 10 kΩ ±1 % resistor, directly determining VOL, swing accuracy, and edge timing over temperature and voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Lane count | 4 independent TMDS lanes; supports arbitrary assignment of IN_D[4:1] to OUT_D[4:1]. |
| Max data rate | 2.5 Gbit/s per lane (250 MHz character clock); meets HDMI v1.3a and DVI v1.0 electrical specs. |
| Supply voltage | 3.3 V ±10 %; consumes 35 mA typical in active mode, 0.8–1.5 mA in standby. |
| HPD logic | Inverting: HPD_SINK HIGH (5 V) → HPD_SOURCE_N LOW (0 V); HPD_SINK LOW → HPD_SOURCE_N HIGH (1.1 V). |
| DDC interface | Pass-gate level shifter; supports 0–400 kHz I²C clock; enables isolation when DDC_EN = LOW. |
| ESD resilience | 8 kV HBM, 500 V CDM; protects against handling and system-level electrostatic discharge. |
| Package | HVQFN48 (SOT619-1); 7 × 7 × 0.85 mm body with exposed thermal pad requiring PCB vias. |
Pinout & Package
HVQFN48 package (SOT619-1) with 48 terminals, 7 × 7 × 0.85 mm footprint, and exposed center thermal pad requiring solder connection and thermal vias for reliable operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_D1+ / IN_D1− to IN_D4+ / IN_D4− | Self-biasing differential inputs | AC-coupled PCIe/DisplayPort–compliant inputs; each pair has integrated 50 Ω termination when OE_N = LOW. |
| OUT_D1+ / OUT_D1− to OUT_D4+ / OUT_D4− | TMDS differential outputs | HDMI/DVI-compliant open-drain current-steering outputs; back-current safe when unpowered. |
| HPD_SINK (pin 30) | 5 V CMOS input | Hot-plug detect input from sink; pulled down by internal 200 kΩ resistor to guarantee LOW when unplugged. |
| HPD_SOURCE_N (pin 7) | 1.1 V CMOS output | Inverted HPD logic output to source; drives 100 µA load with VOL ≤ 0.2 V and VOH ≥ 0.7 V. |
| SCL_SOURCE / SDA_SOURCE (pins 9, 8) | 3.3 V open-drain DDC I/O | Source-side I²C lines; require external 3.3 V pull-up; isolated when DDC_EN = LOW. |
| SCL_SINK / SDA_SINK (pins 28, 29) | 5 V open-drain DDC I/O | Sink-side I²C lines; require external 5 V pull-up; rise-time accelerated for long-cable support. |
| OE_N (pin 25) | CMOS enable input | Active-low control for TMDS path only; disables IN_Dx termination and OUT_Dx drive when HIGH. |
| DDC_EN (pin 32) | CMOS enable input | Active-high control for DDC path only; disconnects SCL/SDA source-sink paths when LOW. |
| REXT (pin 6) | Analog current reference | Connect 10 kΩ ±1 % resistor to GND to set accurate output current; deviation reduces VOL/swing/timing accuracy. |
| VDD (pins 2,11,15,21,26,33,40,46) | 3.3 V supply | Eight dedicated power pins; all must be decoupled locally for stable high-speed operation. |
| GND (pins 1,5,12,18,24,27,31,36,37,43) | Ground return | Ten ground connections including exposed thermal pad; mandatory for EMI, thermal, and signal integrity. |
Key Features
| Feature | Design Value |

| Back-power-safe sink interface | Zero backdrive current on all sink-side pins (TMDS, DDC, HPD) when PTN3360ABS,518 is unpowered. |
| Inverting HPD buffer | Dedicated logic inversion ensures correct source-side HPD signaling without external inverters or software intervention. |
| Configurable power gating | Independent OE_N (TMDS) and DDC_EN (DDC) controls allow granular power management per signal domain. |

FAQ
What is the maximum data rate supported by PTN3360ABS,518 per TMDS lane?
The PTN3360ABS,518 supports up to 2.5 Gbit/s per TMDS lane, corresponding to a 250 MHz character clock. This meets the electrical specifications of HDMI v1.3a and DVI v1.0. Performance is validated with 400 ps unit interval (UI) at 2.5 Gbit/s and maintains ≤7.4 ps added jitter, ensuring signal integrity for high-resolution video transmission using the PTN3360ABS,518.
Does PTN3360ABS,518 require external termination resistors on its differential inputs?
No, the PTN3360ABS,518 integrates 50 Ω termination resistors on all four IN_Dx differential input pairs. These terminations are enabled automatically when OE_N is asserted (LOW). External AC coupling capacitors are still required per input pair, but no additional termination resistors are needed-reducing BOM count and PCB area for the PTN3360ABS,518.
How does the HPD inversion function work in PTN3360ABS,518?
The PTN3360ABS,518 provides inverting HPD translation: when HPD_SINK is HIGH (5 V, indicating monitor presence), HPD_SOURCE_N outputs LOW (0 V); when HPD_SINK is LOW (0 V, unplugged), HPD_SOURCE_N outputs HIGH (1.1 V). This matches HDMI source-side logic expectations and eliminates need for external inverters in the PTN3360ABS,518 signal path.
Can PTN3360ABS,518 operate without the external REXT resistor?
Yes, the PTN3360ABS,518 can operate with REXT left open, tied to VDD, or tied to GND-but output voltage swing (VOL), differential swing accuracy, and rise/fall time consistency degrade over voltage and temperature. For production designs requiring HDMI/DVI compliance, a 10 kΩ ±1 % resistor from REXT to GND is mandatory to ensure PTN3360ABS,518 meets spec limits.
Is PTN3360ABS,518 compatible with DisplayPort source outputs?
Yes, the PTN3360ABS,518 differential inputs comply with DisplayPort v1.1 and PCI Express v1.1 electrical specifications (low-swing AC-coupled differential signaling). It accepts DP/PCIe PHY outputs directly and translates them to HDMI/DVI-compliant TMDS signals-making the PTN3360ABS,518 ideal for multi-mode display sources implementing shared PHY architectures.
