PTN3300BHF,518

Overview

The PTN3300BHF,518 is a high-speed level shifter manufactured by NXP USA Inc. It converts four lanes of low-swing AC-coupled differential input signals to DVI and HDMI compliant open-drain current-steering differential output signals, supporting data rates up to 2.25 Gbit/s per lane. The device operates on a single 3.3 V power supply with typical consumption of 120 mW in active mode. It features integrated 50 Ω termination resistors for self-biasing inputs and provides back-current safe outputs. The package is a 48-terminal HWQFN (SOT1031-2) with dimensions of 7 x 7 x 0.7 mm.

Feature Summary

• Translates low-swing AC-coupled differential inputs to DVI/HDMI compliant TMDS outputs
• Includes dedicated level shifting for DDC channels between 3.3 V and 5 V domains
• Provides non-inverting Hot Plug Detect (HPD) translation from 5 V sink to 3.3 V source
• Supports power-saving standby modes via HPD detection or explicit enable signals

Applications

• Multi-mode display sources requiring support for DisplayPort, HDMI, and DVI standards
• System-on-Chip designs needing transparent level shifting without re-timing
• Portable devices utilizing PCIe PHY electrical configurations for display interfaces

Procurement Notes

Verify the specific ordering suffix ',518' against the manufacturer's latest documentation to confirm packaging details. Confirm that the HWQFN48R package variant matches the required board layout specifications. Ensure compatibility with the 3.3 V supply voltage and check for any RoHS compliance updates in the most recent datasheet revision.

Selection Notes

Select this component when interfacing multi-mode display sources with DVI or HDMI sinks. It is suitable for applications requiring transparent level shifting without software configuration. Consider the PTN3300A if an inverting HPD function at 1.1 V is required instead. For systems needing active DDC buffering and dongle detection, evaluate the PTN3301 as an alternative.

Part Context

This part belongs to the PTN3300 family of DVI and HDMI level shifters. It is designed to allow chipset vendors to implement reconfigurable I/Os on multi-mode display source devices. This enables support for multiple display standards while minimizing the number of chipset I/O pins required for the interface.

Replacement Considerations

The PTN3300BHF2 is a leadframe-based alternative within the same family. The PTN3300A offers identical functionality but with an inverting HPD_SOURCE output. The PTN3301 provides additional features such as active DDC buffering and HDMI dongle detection.
