PTN3355BS/F1MP

Overview

The PTN3355BS/F1MP is a DisplayPort to VGA adapter integrated circuit manufactured by NXP Semiconductors. It converts digital DisplayPort signals into analog RGBHV video for VGA displays, featuring an integrated 1:2 VGA switch suitable for motherboard and docking station designs. The device 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. Powered by a 3.3 V supply, it consumes approximately 200 mW during WUXGA video streaming and enters low-power modes with consumption as low as 410 µW. It includes a high-speed triple video DAC and bridges the VESA DDC channel to the DisplayPort interface.

Feature Summary

• Supports VESA-compliant DisplayPort main link configurations including HBR and RBR data rates with native AUX channel support.
• Integrates a 1:2 VGA switch allowing connection to multiple VGA monitors from a single source.
• Includes internal step-down regulation to generate required core voltages from a single 3.3 V supply.
• Provides monitor detection capabilities through RGB line load sensing and hot-plug detect signaling.

Applications

• Ultra-low power notebook computer primary display adapters
• Docking stations requiring dual VGA port expansion
• Motherboard integrated graphics output solutions

Procurement Notes

Verify the specific suffix F1MP against official NXP documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly planning. Check current lifecycle status as some sources indicate this part may be discontinued; validate availability through authorized distributors if active procurement is required.

Selection Notes

Select this component when designing systems requiring direct conversion from DisplayPort to analog VGA without external bridge chips. Ensure the design accommodates the 40-pin HVQFN package dimensions and thermal dissipation needs. Verify that the host system supports the required DisplayPort lane configurations and AUX channel protocols for proper EDID reading and resolution negotiation.

Part Context

This part belongs to the PTN3355 family of low-power DisplayPort to VGA adapters. It is specifically optimized for space-constrained and power-sensitive applications such as mobile computing devices. The integration of the VGA switch distinguishes it from basic converter-only ICs, offering enhanced connectivity options for docking scenarios.

Replacement Considerations

Check NXP's official obsolescence notices for this part number. If discontinued, consult the manufacturer's recommended replacement list for equivalent DP-to-VGA converters with similar pinouts and electrical characteristics. No public substitute part numbers are confirmed in the provided data.
