PTN3392BS/F3,518

Overview

The PTN3392BS/F3,518 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 operates within a commercial temperature range of 0 °C to 85 °C in a 48-pin HVQFN package.

Feature Summary

• Supports VESA-compliant DisplayPort v1.1a conversion with HBR and RBR modes
• Integrates triple 8-bit DACs for analog RGB current-source outputs
• Enables I2C-bus over AUX for full support of MCCS and DDC protocols
• Includes monitor presence detection via load sensing and HPD reporting

Applications

• Dongle PC accessory connecting PC DisplayPort output to RGB monitors
• Desktop and notebook computers requiring legacy display connectivity
• Notebook docking stations providing VGA ports for external displays

Procurement Notes

Verify the specific firmware version associated with the 'F3' suffix against NXP documentation before procurement. Confirm that the component status aligns with project lifecycle requirements, as availability may be limited. Ensure the ordering part number matches the required packing method and reel specifications for automated assembly processes.

Selection Notes

Select this component when interfacing DisplayPort sources with standard VGA sinks requiring VSIS 1.2 compliance. Consider the S2 pin configuration for default I2C speed settings, which differs between firmware versions. Evaluate power consumption requirements, noting active mode usage varies with resolution and pixel clock rates. Ensure the application design accommodates the 48-pin HVQFN package thermal requirements.

Part Context

The PTN3392 series serves as a bridge solution for integrating modern DisplayPort interfaces with legacy VGA displays. The PTN3392BS/F3 variant specifically denotes a unit with a defined firmware version, distinct from the latest release found in the base PTN3392BS model. This differentiation allows for controlled firmware deployment in specific hardware revisions or legacy system maintenance scenarios.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing DisplayPort sources and VGA sinks if direct replacement is attempted.
