PTN3360ABS,518

Overview

The PTN3360ABS is a high-speed level shifter designed to convert four lanes of low-swing AC-coupled differential input signals into DVI v1.0 and HDMI v1.3a compliant open-drain current-steering differential output signals, supporting up to 2.5 Gbit/s per lane. It features integrated 50 Ω termination resistors for self-biasing inputs and provides active level shifting for the DDC channel between 3.3 V source-side and 5 V sink-side. The device includes an inverting HPD buffer translating from 5 V on the sink side to 1.1 V on the source side. Powered by a single 3.3 V supply with typical consumption of 120 mW, it is housed in a 48-terminal HVQFN48 package.

Feature Summary

• Translates four lanes of low-swing AC-coupled differential inputs to DVI/HDMI compliant outputs
• Provides active level shifting for DDC channels between 3.3 V and 5 V domains
• Features inverting Hot Plug Detect (HPD) translation from 5 V to 1.1 V
• Includes back-current-safe designs on all sink-side terminals

Applications

• Multi-mode display sources requiring support for multiple display standards
• System implementations needing transparent level shifting without re-timing
• Interfaces connecting PCIe PHY electrical configurations to DVI or HDMI sinks

Procurement Notes

Verify component authenticity through authorized NXP distributors. Confirm package marking matches the HVQFN48 designation. Ensure ordering suffixes align with specific tape-and-reel requirements if applicable. Cross-reference datasheet revision dates to confirm feature consistency before procurement.

Selection Notes

Select this component when interfacing low-swing AC-coupled sources like DisplayPort or PCIe with standard DVI or HDMI sinks. It is suitable for applications requiring transparent level shifting without software configuration. Consider its power-saving modes and back-power safety features for systems where the sink may be powered while the shifter is inactive.

Part Context

The PTN3360A series serves as an enhanced performance alternative to the PTN3300A, offering higher speed capabilities and improved ESD robustness. While functionally similar to the PTN3360B, the PTN3360ABS specifically distinguishes itself by providing inverting level shifting on the HPD channel, catering to specific logic requirements in display interface designs.

Replacement Considerations

PTN3360BBS is a functional equivalent but lacks the inverting HPD characteristic found in the PTN3360ABS. Designers must verify HPD logic polarity requirements when substituting. Other family members like PTN3360D include active DDC buffers and support higher speeds, which may require schematic adjustments.
