PTN3381DBS,518

Video Processing Overview

The PTN3381DBS,518 is a high-speed level shifter converting four lanes of low-swing AC-coupled differential inputs to DVI v1.0 and HDMI v1.4b compliant outputs up to 3 Gbit/s per lane. It supports 36-bit deep color and 3D modes. The device operates on a single 2.85 V to 3.6 V supply and includes an onboard 5 V DC regulator requiring only two external capacitors. It features integrated 50 Ω input termination, programmable equalization via the EQ5 pin, and active DDC buffering with rise time acceleration.

Video Processing Feature Summary

• Converts low-swing AC-coupled differential signals to TMDS-type DC-coupled current-mode signaling
• Includes an onboard 5 V DC voltage regulator eliminating the need for external regulators
• Provides active I2C-bus buffering and level shifting for DDC channels with rise time acceleration
• Supports HDMI dongle detection through an integrated I2C slave ROM responding to specific read commands

Video Processing Applications

• DisplayPort to HDMI adapters supporting 36-bit deep color and 3D modes
• DisplayPort to DVI adapters designed to drive long cables
• Multi-mode display source devices requiring reconfigurable I/O support

Video Processing Procurement Notes

Verify the exact ordering suffix matches the required package variant. Confirm that the component meets RoHS3 compliance standards as specified in the datasheet. Ensure the design accounts for the exposed thermal pad requirements for proper grounding and heat dissipation in the HVQFN48 package.

Video Processing Selection Notes

Select this component when integrating multi-mode display sources into HDMI or DVI sinks. It is suitable for designs requiring transparent level shifting without data retiming. Consider its back-power safe design for scenarios where the sink remains powered while the source is inactive.

Video Processing Part Context

The PTN3381D supersedes the PTN3381B model, offering improved high-speed performance with a programmable equalizer. It is functionally equivalent to the PTN3381D but distinguishes itself by including an onboard 5 V regulator. The device is part of NXP's portfolio for video processing and interface control.

Video Processing Replacement Considerations

The PTN3381B is listed as superseded by the PTN3381D series. Verify compatibility if substituting older inventory.
