PTN3360DBS,518

Overview

The PTN3360DBS,518 is a high-speed level shifter that converts four lanes of low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.4b compliant open-drain current-steering differential output signals. It supports data rates up to 3.0 Gbit/s per lane for 36-bit deep color mode, 4K x 2K video, or 3D video transport. The device operates from a single 3.0 V to 3.6 V power supply with typical consumption of 70 mA in active mode. It features integrated 50 Ω termination resistors, back-current safe outputs, and an active DDC buffer with rise time acceleration.

Feature Summary

• Converts low-swing AC-coupled differential inputs to DVI/HDMI compliant TMDS outputs
• Provides active buffering and level shifting for the DDC channel between 3.3 V and 5 V domains
• Includes HPD signal translation from 5 V sink-side to 3.3 V source-side
• Features programmable equalizer settings and back-power safe design on all sink-side terminals

Applications

• PC motherboard and graphics card display interfaces
• Docking stations requiring multi-mode display support
• DisplayPort to HDMI adapters supporting 4K x 2K and 3D video formats
• DisplayPort to DVI adapters driving long cables

Procurement Notes

Verify the component matches the PTN3360D datasheet specifications before integration. Confirm the HVQFN48 package variant aligns with PCB footprint requirements. Ensure thermal vias are incorporated under the exposed pad for proper heat dissipation. Check that the ordering suffix corresponds to the specific tape-and-reel configuration required for assembly processes.

Selection Notes

Select this device when interfacing multi-mode sources like DisplayPort or PCIe PHYs with standard DVI or HDMI sinks. It is suitable for designs requiring transparent level shifting without re-timing. Consider the programmable equalizer for optimizing signal integrity over varying trace lengths. Ensure the system supports the required 3.3 V and 5 V voltage domains for proper operation of the TMDS and DDC channels respectively.

Part Context

The PTN3360DBS,518 is part of the PTN3360D family, superseding the PTN3360B model. It provides enhanced high-speed performance through a programmable equalizer. The device is designed to allow chipset vendors to implement reconfigurable I/Os on multi-mode display sources, supporting multiple standards while minimizing pin counts.

Replacement Considerations

The PTN3360B is the predecessor model. Verify if the improved equalizer performance of the PTN3360D is required for the specific application.
