PTN3393BS/F1Y

Overview

The PTN3393BS/F1Y 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, I2C-bus over AUX support, and bridges the VESA DDC channel. Powered by a single 3.3 V supply, it includes monitor presence detection and operates within a commercial temperature range of 0 °C to 85 °C in a 40-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 field upgradability via Flash-over-AUX capability
• Provides monitor presence detection through load sensing and HPD signaling

Applications

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

Procurement Notes

Verify the specific firmware version associated with the FX suffix before procurement, as ordering suffixes indicate distinct firmware revisions. Confirm package availability and lead times directly with authorized distributors or NXP Semiconductors representatives. Ensure compliance with RoHS and REACH requirements specified in the material declaration. Check for any obsolescence notices or end-of-life notifications prior to finalizing orders.

Selection Notes

Select this component when interfacing DisplayPort sources with standard VGA sinks requiring cost-effective conversion. Consider the 40-pin HVQFN package constraints and thermal pad soldering requirements for PCB layout. Evaluate power consumption levels relative to system cooling capabilities, noting active mode usage varies with resolution. Verify that the host system supports the required DisplayPort link rates and lane configurations for the target resolution.

Part Context

The PTN3393 series serves as a bridge between modern digital display interfaces and legacy analog monitors. It addresses the need for backward compatibility in computing environments where VGA displays remain prevalent. The device simplifies design by integrating necessary receiver and DAC functions into a single chip, reducing external component count and board space compared to discrete solutions.

Replacement Considerations

PTN3393BS uses the latest firmware version. PTN3393BS/FX uses specific firmware versions (e.g., F1, F2, F3). Verify if the application requires a specific firmware revision compatible with the host controller. No direct functional replacements are listed in the provided documentation.
