PTN3392BS/F4Y

Overview

The PTN3392BS/F4Y is a DisplayPort to VGA adapter IC designed to connect DisplayPort sources to VGA sinks. 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 (HBR) or 1.62 Gbit/s (RBR) per lane, with a bit error rate better than 10^-9. It features Flash-over-AUX for firmware upgradability and bridges the VESA DDC channel via I2C-bus over AUX. Powered by a single 3.3V supply, it minimizes application costs and includes monitor detection capabilities.

Feature Summary

• Supports DisplayPort v1.1a main link in one-lane and two-lane modes with HBR and RBR rates
• Integrates Flash-over-AUX capability for simple field firmware upgradability
• Bridges VESA DDC channel to DisplayPort interface with I2C-bus over AUX support
• Enables direct powering from DisplayPort source side 3.3V supply without additional regulators

Applications

• Connecting DisplayPort sources to VGA sinks
• Cost-effective VGA adapter designs
• Monitor detection systems requiring sink connection status reporting

Procurement Notes

Verify component authenticity through authorized distributors as this part is discontinued. Check manufacturing date codes against historical availability records. Ensure compliance with RoHS and REACH SVHC declarations specified for the PTN3392BS/F4Y variant. Confirm package integrity for HVQFN48 before integration into legacy systems.

Selection Notes

Select this component for applications requiring DisplayPort to VGA conversion with firmware upgradability. Consider the HVQFN48 package constraints and MSL level 3 requirements during PCB design. Evaluate thermal performance given the 260°C lead-free soldering peak temperature limit. Verify compatibility with DisplayPort v1.1a sources supporting HBR or RBR rates.

Part Context

The PTN3392BS/F4Y belongs to the PTN3392 family of DisplayPort to VGA adapter ICs manufactured by NXP Semiconductors. It shares core functionality with variants like PTN3392BS and PTN3392BS/F1 but differs in specific ordering suffixes indicating packaging or reel configurations. All variants are classified as No Longer Manufactured, serving historical reference purposes for existing designs.

Replacement Considerations

No public confirmed substitute part numbers are available for the PTN3392BS/F4Y. Designers should consider redesigning with newer DisplayPort controllers or consulting NXP for alternative solutions compatible with current production lines.
