PTN3356R1BSZ

Overview

The PTN3356R1BSZ is a ROM-based DisplayPort to VGA adapter IC optimized 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 capable of pixel clocks up to 240 MHz. 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.

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
• Bridges VESA DDC channel to the DisplayPort Interface via I2C-over-AUX
• Includes monitor presence detection through RGB line load sensing

Applications

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

Procurement Notes

Verify the specific ordering part number against the manufacturer's current product data sheet before procurement. Confirm that the HVQFN32 package dimensions and thermal pad requirements match the target PCB layout. Ensure the design supports the required 3.3 V power supply and external crystal oscillator frequencies as specified in the functional description.

Selection Notes

Select this component when a compact, low-power solution is needed to bridge DisplayPort sources to legacy VGA displays on motherboards. Consider the 32-pin HVQFN package size constraints and the requirement for an external reference resistor for DAC output levels. Verify compatibility with the source's DisplayPort link rate and lane configuration capabilities.

Part Context

This component belongs to NXP's family of DisplayPort to analog video bridge ICs. It is designed to facilitate the transition from digital display interfaces to standard analog VGA connectors in computing platforms. The integrated nature of the receiver and DAC simplifies system design by reducing the bill of materials compared to discrete solutions.
