PTN3356BS/F1Z

Overview

The PTN3356BS/F1Z is a flash-based DisplayPort to VGA adapter IC designed for motherboard applications. It converts DisplayPort signals from the chipset into analog video signals for direct connection to VGA connectors. The device integrates a DisplayPort receiver supporting two lanes at 2.7 Gbit/s or 1.62 Gbit/s per lane, and a triple 8-bit video DAC. Powered by a single 3.3 V supply, it consumes approximately 200 mW during WUXGA streaming and 410 μW in low-power mode. It operates within a commercial temperature range of 0 °C to 85 °C and is housed in a 32-pin HVQFN package measuring 5 mm x 5 mm x 0.85 mm.

Feature Summary

• Supports VESA-compliant DisplayPort Main Link with HBR and RBR rates
• Integrates a high-speed triple 8-bit video digital-to-analog converter
• Provides I2C-over-AUX functionality for DDC channel bridging
• Includes monitor presence detection via RGB line load sensing

Applications

• Notebook computers
• Tablets and desktop PCs
• Dongles, adapters, and docking stations

Procurement Notes

Verify that the specific suffix 'Z' corresponds to the 7-inch reel packing method as documented in the ordering information table. Confirm the firmware version associated with the 'F1' designation matches the required system configuration. Ensure the component meets RoHS compliance standards before integration into the final assembly process.

Selection Notes

Select this component when a compact solution is required to bridge DisplayPort sources to legacy VGA displays. Consider the power consumption differences between DC-to-DC converter mode and LDO mode based on thermal constraints. Verify that the host system supports the necessary crystal oscillator frequencies of 24 MHz, 25 MHz, or 27 MHz for proper clock generation.

Part Context

This part belongs to NXP's family of flash-based DisplayPort to VGA adapters. It serves as a specialized interface controller optimized for low-power embedded platforms. The device simplifies design-in by integrating both the DP receiver PHY and the analog video output stage into a single small footprint.

Replacement Considerations

PTN3392BS is a discontinued alternative. Verify pin compatibility and firmware requirements if substituting.
