PTN3356BS/F2MP

Overview

The PTN3356BS/F2MP is a flash-based DisplayPort to VGA adapter designed for motherboard applications. It converts DisplayPort signals from the chipset to analog video for direct connection to VGA connectors. The device integrates a DisplayPort receiver supporting two lanes at 2.7 Gbit/s or 1.62 Gbit/s per lane, and a high-speed triple 8-bit video DAC. It operates on a single 3.3 V power supply with approximately 200 mW consumption at WUXGA resolution and 410 µW in low-power mode. The component supports resolutions up to 240 MHz pixel clock rate and includes DDC channel bridging via I2C-over-AUX.

Feature Summary

• VESA-compliant DisplayPort v1.4 converter supporting HBR and RBR link rates
• Triple 8-bit digital-to-analog converter for analog RGB current-source outputs
• Integrated monitor presence detection through load sensing on RGB lines
• Supports native AUX CH syntax and I2C-bus over AUX CH protocol

Applications

• Notebook computers
• Tablets and desktop PCs
• Dongles, adapters, and docking stations

Procurement Notes

Verify the specific firmware version associated with the 'F2' suffix by consulting the manufacturer's ordering information table. Confirm that the HVQFN32 package dimensions and thermal pad requirements match the PCB layout specifications. Ensure the design accounts for the exposed die pad connection to supply ground for proper operation.

Selection Notes

Select this component when a compact solution is required to bridge DisplayPort sources to legacy VGA displays. Consider the 32-pin HVQFN package size for space-constrained designs. Verify compatibility with the source device's DisplayPort version and lane configuration capabilities before integration.

Part Context

This part belongs to NXP's family of flash-based DisplayPort to VGA adapters. It is optimized primarily for motherboard applications where direct conversion from digital DisplayPort signals to analog VGA is necessary. The device simplifies system design by integrating both the receiver and the video DAC subsystems.

Replacement Considerations

Check for other variants within the PTN3356 series that may have different firmware versions indicated by the 'Fx' suffix. Ensure any substitute maintains the same HVQFN32 package footprint and pinout compatibility.
