PTN3363BSMP

Overview

The PTN3363BSMP is a low-power, high-speed level shifter designed to convert four lanes of low-swing AC-coupled differential input signals into DVI v1.0 and HDMI v1.4b compliant open-drain current-steering differential output signals. It supports data rates up to 3.4 Gbit/s per lane, enabling the transport of 36-bit deep color, 4K x 2K video formats, and 3D video data. The device operates on a single 3.3 V power supply (2.8 V to 3.6 V range) with typical power consumption of 72 mW. It integrates active buffering for HPD and DDC channels, providing voltage translation between 3.3 V source-side and 5 V sink-side domains while ensuring back-current safety.

Feature Summary

• Converts low-swing AC-coupled differential inputs to DVI/HDMI compliant TMDS outputs with integrated equalization
• Provides active buffering and level shifting for DDC I2C-bus channels between 3.3 V and 5 V domains
• Includes non-inverting Hot Plug Detect (HPD) level shifting with integrated pull-down resistor
• Features back-current-safe design on all sink-side terminals to prevent backdrive when unpowered
• Supports HDMI dongle detection via an internal I2C-bus slave ROM accessible through the DDC channel

Applications

• PC motherboards and graphics cards requiring multi-mode display support
• Docking stations facilitating connection to external displays
• DisplayPort to HDMI adapters supporting 4K x 2K and 3D video formats
• DisplayPort to DVI adapters designed to drive long cable runs

Procurement Notes

Verify the ordering part number PTN3363BSMP corresponds to the HVQFN32 package in the SOT617-3 version. Confirm the temperature range is -40 °C to +105 °C. Ensure the component is sourced from authorized distributors to guarantee authenticity. Check for RoHS compliance status as indicated in the product data sheet. Validate that the specific batch matches the required thermal and electrical specifications for your application.

Selection Notes

Select this component when interfacing multi-mode display sources with DVI or HDMI sinks requiring transparent level shifting without retiming. It is suitable for designs needing support for 4K x 2K and 3D video at up to 3.4 Gbit/s per lane. Consider its integrated DDC buffering and rise time acceleration if driving high capacitance loads. Ensure the system can accommodate the 32-terminal HVQFN32 package and provide adequate thermal grounding via the exposed pad.

Part Context

The PTN3363 is part of NXP's portfolio of high-speed interface solutions, specifically targeting display connectivity applications. It bridges the gap between DisplayPort/PCI Express electrical configurations and DVI/HDMI standards. The device enables chip set vendors to implement reconfigurable I/Os on multi-mode display sources, reducing pin counts while maintaining compatibility with multiple display standards.
