PTN3392BS/F1,518

Overview

The PTN3392BS/F1,518 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 VESA-compliant DisplayPort v1.1a conversion with main link modes for HBR and RBR data rates.
• Integrates a triple 8-bit video DAC providing analog RGB current-source outputs compliant with VSIS 1.2.
• Enables I2C-bus over AUX functionality to facilitate full support of MCCS, DDC-CI, and DDC protocols.
• Includes built-in monitor presence detection that reports connection status changes to the source.

Applications

• Dongle PC accessory connecting PC DisplayPort output to RGB monitors
• Desktop and notebook computers
• Notebook docking stations

Procurement Notes

Verify the specific ordering suffix 'F1' corresponds to the required firmware version before procurement. Confirm package details match the HVQFN48 specification. Check environmental compliance certificates such as RoHS and REACH SVHC status. Ensure the component status aligns with project lifecycle requirements as availability may vary.

Selection Notes

Select this part when converting DisplayPort signals to analog VGA is required. Ensure the design accommodates the 3.3 V single supply requirement. Verify that the target display resolutions fall within the supported range up to WUXGA. Consider the external crystal oscillator requirement for clock generation.

Part Context

This component belongs to the PTN3392 family of bridge ICs manufactured by NXP Semiconductors. It serves as a specialized solution for bridging digital DisplayPort interfaces to legacy analog VGA displays. The device is distinct from other bridge solutions like the PTN3460 which targets embedded DisplayPort to LVDS conversion.

Replacement Considerations

PTN3392BS,518 and PTN3392BS/F4Y are alternative orderable parts within the same family offering different firmware versions. No direct functional replacements outside the PTN3392 series are documented in the provided datasheet.
