PTN3380BBS,518

Video Processing Overview

The PTN3380BBS,518 is a high-speed DVI level shifter with an integrated voltage regulator. It converts four lanes of low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.3a compliant open-drain current-steering differential output signals, supporting up to 1.65 Gbit/s per lane. The device operates on a single 3.3 V power supply (3.0 V to 3.6 V) and includes an onboard 5 V DC regulator capable of providing up to 75 mA load current. It features back-current-safe outputs, HPD level shifting from 5 V to 3.3 V, and DDC channel level shifting between 3.3 V and 5 V.

Video Processing Feature Summary

• Converts low-swing AC-coupled differential inputs to DVI/HDMI compliant TMDS outputs
• Integrates a 5 V DC regulator requiring only two external capacitors
• Provides back-power safe design for sink-side terminals to prevent backdrive current
• Supports transparent operation without data re-timing or software configuration

Video Processing Applications

• DisplayPort to DVI adapters
• Consumer video dongle applications

Video Processing Procurement Notes

Verify component authenticity through authorized NXP distributors. Confirm the specific ordering suffix matches the HVQFN48 package variant. Check RoHS compliance status as indicated in official documentation. Ensure storage conditions adhere to the specified moisture sensitivity level requirements prior to assembly.

Video Processing Selection Notes

Select this component when designing multi-mode display sources requiring conversion to DVI standards. It is suitable for applications needing integrated 5 V regulation for connector power. Consider the PTN3381B if HDMI adapter functionality is required instead of DVI. Evaluate PCB layout constraints for the exposed thermal pad in the HVQFN48 package.

Video Processing Part Context

This part belongs to the PTN33 series of video interface controllers manufactured by NXP USA Inc. It serves as a fully featured DVI level shifter, functionally comparable to the PTN3360B but distinguished by its onboard 5 V regulator. The device is designed to support multiple display standards while minimizing chipset I/O pin usage.

Video Processing FAQ

Does the PTN3380B re-time data signals?

No, the PTN3380B acts as a transparent level shifter and does not re-time any data.

What is the purpose of the REXT pin?

The REXT pin provides an accurate current reference for the differential outputs to ensure optimal output voltage swing accuracy.
