PTN3355BS/F3MP

Overview

The PTN3355BS/F3MP is a DisplayPort to VGA adapter integrated circuit manufactured by NXP Semiconductors. It converts digital DisplayPort signals into analog RGBHV video for VGA displays. The device integrates a DisplayPort receiver, a high-speed triple video digital-to-analog converter, and a 1:2 VGA switch. It supports one or two DisplayPort lanes operating at High Bit Rate (HBR) of 2.7 Gbit/s per lane or Reduced Bit Rate (RBR) of 1.62 Gbit/s per lane. The component operates from a single 3.3 V power supply, consuming approximately 200 mW during WUXGA video streaming and 410 µW in low-power mode.

Feature Summary

• Supports VESA-compliant DisplayPort main link modes including HBR and RBR with bit error rates better than 10^-9
• Integrates a 1:2 VGA switch allowing connection of multiple VGA monitors to a single source
• Bridges the VESA DDC channel to the DisplayPort interface for monitor detection and EDID handling
• Includes active high hot plug detect signal generation and load sensing on RGB lines

Applications

• Motherboard video output adapters
• DisplayPort to VGA docking stations
• Video extension cables and converters

Procurement Notes

Verify the specific suffix F3MP against official NXP documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check current availability as product lifecycles may change. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this component when a system requires converting a DisplayPort source signal to an analog VGA destination. The integrated 1:2 switch allows driving two VGA displays from one DP source. Verify that the host system supports the required lane count and bit rate for the target resolution. Ensure the design accommodates the 3.3 V power requirement and thermal dissipation for the HVQFN package.

Part Context

This part belongs to the PTN3355 series of low-power DisplayPort to VGA adapters. The series is optimized for motherboard applications where space and power consumption are critical constraints. It serves as a bridge between modern digital display interfaces and legacy analog monitors. The device simplifies design by integrating the receiver, DAC, and switching logic into a single small footprint.

Replacement Considerations

Check NXP datasheets for direct pin-compatible alternatives within the PTN3355 family. Verify if other suffixes offer different packaging options such as trays versus reels. Ensure any substitute maintains the same electrical characteristics and support for HBR/RBR modes.
