PTN3392BS/F2,518

Overview

The PTN3392BS/F2,518 is a DisplayPort to VGA adapter IC designed to connect a DisplayPort source to a VGA sink. It integrates a DisplayPort receiver and a high-speed triple video digital-to-analog converter supporting resolutions from VGA to WUXGA. The device supports one or two DisplayPort v1.1a lanes operating at 2.7 Gbit/s or 1.62 Gbit/s per lane. It features 'Flash-over-AUX' capability for firmware upgradability and bridges the VESA DDC channel to the DisplayPort interface. Powered by a single 3.3 V supply, it minimizes application costs and includes monitor detection via load sensing.

Feature Summary

• Supports I2C-bus over AUX and native AUX CH syntax per DisplayPort v1.1a specification
• Integrates a high-speed triple 8-bit video DAC with analog RGB current-source outputs
• Provides monitor presence detection and reports connection status via HPD IRQ
• Enables simple field firmware upgradability through Flash-over-AUX capability

Applications

• Dongle PC accessory connecting PC DisplayPort output to RGB monitors
• Desktop and notebook computers requiring legacy display connectivity
• Notebook docking stations facilitating external monitor attachment

Procurement Notes

Verify the specific firmware version associated with the '/F2' suffix against official documentation before procurement. Confirm that the HVQFN48 package dimensions and thermal pad requirements align with your PCB layout specifications. Ensure compatibility with the required DisplayPort source capabilities regarding lane count and bit rate support.

Selection Notes

Select this component when interfacing DisplayPort sources with standard VGA sinks requiring resolution support up to WUXGA. Consider the 3.3 V single-supply operation and integrated LDO capabilities for simplified power design. Evaluate the need for specific firmware versions indicated by the ordering suffix if custom initialization or behavior is required for the target application.

Part Context

The PTN3392 belongs to NXP's bridge IC solutions portfolio, specifically targeting display connectivity applications. It serves as a specialized adapter converting high-speed digital DisplayPort signals into analog VGA formats. This family of components facilitates backward compatibility in modern computing environments where legacy analog displays remain in use alongside newer digital interfaces.
