Product details
Overview
PTN3356BS/F1Z from NXP Semiconductors is a flash-based DisplayPort-to-VGA adapter IC designed for motherboard-level video interface bridging, integrating a VESA-compliant DisplayPort 1.2a receiver, triple 8-bit DACs, and I²C-over-AUX DDC bridging. It supports dual-lane DP input at 2.7 Gbit/s (HBR) or 1.62 Gbit/s (RBR), delivers up to 240 MHz pixel clock, and drives standard 75 Ω VGA loads with 700 mVpp analog RGB outputs - enabling WUXGA (1920×1200@60 Hz) in desktop and notebook platforms.
For engineers reviewing the PTN3356BS/F1Z datasheet, PTN3356BS/F1Z pinout, PTN3356BS/F1Z application, or PTN3356BS/F1Z equivalent, this page provides verified functional context, validated pin roles, confirmed power and timing specifications, and real-world VGA conversion use cases - all grounded in NXP's official Rev. 3 product data sheet dated 13 January 2015.
Technical Context
The PTN3356BS/F1Z implements a full DisplayPort 1.2a sink PHY with auto-receive equalization and CDR, supporting both RBR and HBR link rates across one or two lanes. Its digital subsystem extracts main stream video attributes during vertical blanking and reconstructs synchronized RGB timing using recovered pixel clock and frame geometry metadata.
It integrates native I²C-over-AUX protocol translation to bridge the DisplayPort source's DDC access to the VGA monitor's EDID/CI bus, while maintaining HPD signaling integrity via active-HIGH IRQ and DPCD register updates. Monitor presence detection uses periodic RGB line load sensing - not passive pull-up - to report sink connection status without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DisplayPort-to-VGA adapter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S016 | Dual-function ESD protector + level shifter; lacks integrated DAC, DP receiver, or firmware - requires external DP sink and VGA DAC | Only suitable as companion IC in hybrid designs; cannot replace PTN3356BS/F1Z standalone functionality | Select only when augmenting an existing DP sink design with ESD and level-shifting - not a functional alternative |
| Parade PS8315 | DP-to-LVDS bridge with integrated timing controller; no VGA analog output, DAC, or DDC bridging capability | Targets LVDS panels, not CRT/projector displays; incompatible pinout, power architecture, and firmware model | Choose only for LVDS-based industrial displays - not applicable for VGA signal generation or EDID passthrough |
Compared with TI TPD12S016 and Parade PS8315, PTN3356BS/F1Z uniquely delivers end-to-end DP-to-analog VGA conversion in a single chip - including receiver, DAC, DDC bridge, and monitor detection - whereas alternatives require multi-chip implementations or serve entirely different display interfaces.

FAQ
What display resolutions does PTN3356BS/F1Z support?
PTN3356BS/F1Z supports resolutions from VGA (640×480@60 Hz) up to WUXGA (1920×1200@60 Hz) and UXGA (1600×1200@60 Hz), with pixel clock rates up to 240 MHz at 6 bpc or 180 MHz at 8 bpc. It handles reduced-blanking modes and all standard VGA colorimetry formats (RGB), as confirmed in Table 8 of the NXP datasheet Rev. 3.
Does PTN3356BS/F1Z require external firmware loading?
No, PTN3356BS/F1Z is flash-based and ships with factory-programmed firmware enabling immediate operation. The "F1Z" suffix denotes firmware version 1; no external programming tool or host driver is needed for basic DP-to-VGA conversion, though optional utilities exist for lab-level register tuning.
How does PTN3356BS/F1Z handle VGA monitor detection?
PTN3356BS/F1Z performs active load sensing on the RED, GRN, and BLU analog output lines - pulsing them to detect 75 Ω termination - and reports connection status via HPD IRQ and DPCD register updates. This eliminates reliance on DDC pull-ups and prevents false disconnects common in passive schemes.
What power supply configuration is required for PTN3356BS/F1Z?
PTN3356BS/F1Z operates from a single 3.3 V supply applied to VDDA33_DNW, VDDE33_IO, and PVDD33. Internal 1.5 V rails (for DP PHY and DAC) are generated via the SWOUT switching regulator output, which must be connected to VDDA15_DP, VDDA15_DAC, and VDDD15 as shown in Figure 4 of the datasheet.
Can PTN3356BS/F1Z support 5 V HSYNC/VSYNC for legacy CRT monitors?
PTN3356BS/F1Z outputs 3.3 V HSYNC and VSYNC signals. To drive 5 V legacy CRTs, external level-shifting circuitry (e.g., 74LVC2G125DP buffer) is required - as illustrated in the "OPTION DESIGN" section of Figure 4 in the NXP datasheet. The IC itself does not provide 5 V tolerant sync outputs.
