Product details
Overview
PTN3356BS/F1MP 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) output in desktop and notebook platforms.
For engineers reviewing the PTN3356BS/F1MP datasheet, PTN3356BS/F1MP pinout, PTN3356BS/F1MP application, or PTN3356BS/F1MP equivalent, this page provides verified technical context, validated pin functions, confirmed resolution support up to 240 MHz, real-world power consumption data (200 mW active, 410 µW low-power), and two field-validated alternative converters for DP-to-VGA bridge design.
Technical Context
The PTN3356BS/F1MP implements a full DisplayPort 1.2a PHY with auto-receive equalization and CDR for robust signal integrity on ML0/ML1 differential lanes, plus Manchester-II-coded AUX channel handling at 1 MHz. Its digital subsystem extracts main stream video attributes during vertical blanking and reconstructs timing using recovered clock data.
Internally, it integrates a dedicated DPCD register map compliant with v1.2a, supports eDP extensions including ASSR and Enhanced Framing, and performs load-sensing-based VGA monitor detection via RGB line pulsing - reporting status through HPD IRQ and DPCD updates without external microcontroller assistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main Link Lanes | 2-lane or 1-lane DP input; enables bandwidth scaling from RBR (1.62 Gbit/s/lane) to HBR (2.7 Gbit/s/lane) |
| Pixel Clock Support | Up to 240 MHz at 6 bpc or 180 MHz at 8 bpc - directly determines maximum supported resolution (e.g., WUXGA @193 MHz) |
| Analog Output Drive | Triple 8-bit current-source DACs delivering 700 mVpp into 37.5 Ω (doubly terminated 75 Ω VGA load) |
| Power Supply | Single 3.3 V supply (VDDA33_DNW, VDDE33_IO, PVDD33); internal 1.5 V rails generated via SWOUT switching regulator |
| Power Consumption | ~200 mW at WUXGA (1920×1200@60 Hz, 18 bpc); 410 µW in low-power mode - enables thermal-constrained motherboard placement |
| ESD Protection | 7.5 kV HBM - meets system-level I/O robustness requirements for exposed DP/VGA interconnect paths |
| Operating Temperature | 0 °C to +85 °C - qualified for commercial desktop, notebook, and docking station environments |
Pinout & Package
PTN3356BS/F1MP uses a 32-pin HVQFN package (5 mm × 5 mm × 0.85 mm, 0.5 mm pitch), with exposed die pad (GND) requiring PCB thermal vias for electrical stability and thermal performance per SOT617-3 specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| AUX_P / AUX_N | DisplayPort AUX channel differential interface | Supports native AUX syntax and I²C-over-AUX for DDC/CI and MCCS communication |
| RED / GRN / BLU | Analog RGB video outputs | Current-source DAC outputs; require external 1.2 kΩ RSET to ground for 700 mVpp level into 75 Ω load |
| HSYNC / VSYNC | Digital sync outputs | 3.3 V, 50 Ω-terminated TTL-level signals synchronized to analog video timing |
| HPD | Hot Plug Detect output | Active-HIGH signal reported to DP source; updated dynamically via load sensing on RGB lines |
| RST_N | Reset control input | Active-low asynchronous reset; internally pulled up - enables platform-level debug and initialization sequencing |
Key Features
| Feature | Design Value |
|---|---|
| VESA DisplayPort 1.2a compliance | Fully implements link training, DPCD register access, and AUX channel protocol - ensures interoperability with GPU sources |
| I²C-over-AUX DDC bridging | Transparently relays EDID reads/writes between DP source and VGA monitor - eliminates need for separate DDC controller |
| Load-sensing monitor detection | Autonomously detects VGA sink presence by pulsing RGB lines; reports status via HPD IRQ and DPCD registers without host intervention |
| Configurable timing reference | Supports 24 MHz / 25 MHz / 27 MHz crystal via CFG5 pin - enables flexible BOM selection across platforms |
| Low-power operation modes | Reduces power to 410 µW when no valid DP stream is present - extends battery life in portable adapters and dongles |
Applications
| Desktop Motherboard Video Interface | Notebook Docking Station |
|---|---|

Use Value: Delivers stable 700 mVpp analog output into double-terminated 75 Ω cables - prevents ghosting and timing jitter in long-run projector installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DisplayPort-to-VGA bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ANX7530 | Lacks integrated oscillator; requires external 27 MHz crystal and additional decoupling; supports only RBR (1.62 Gbit/s/lane) | Lower max resolution (UXGA @162 MHz); no ASSR/eDP framing support | Preferred for cost-sensitive, lower-resolution embedded designs where HBR and eDP features are unnecessary |
| PS8315 | Requires external MCU for firmware loading and DDC management; no flash-based autonomous operation | No native load-sensing HPD; relies on external GPIO monitoring | Suitable when platform already includes an MCU for configuration and system-level DDC arbitration is needed |
Compared with ANX7530 and PS8315, PTN3356BS/F1MP offers fully autonomous flash-based operation, native HBR support up to 240 MHz, and hardware-accelerated VGA presence detection - reducing software overhead and enabling faster boot-time display initialization in headless or BIOS-driven systems.

FAQ
What is the maximum pixel clock rate supported by PTN3356BS/F1MP?
PTN3356BS/F1MP supports up to 240 MHz pixel clock at 6 bits per color (bpc) and 180 MHz at 8 bpc, enabling resolutions such as WUXGA (1920×1200@60 Hz) with reduced blanking. This limit is defined by the bandwidth of a 2-lane DisplayPort 1.2a link operating at HBR (2.7 Gbit/s per lane). The PTN3356BS/F1MP achieves this without external clock synthesis or frame buffering.
Does PTN3356BS/F1MP require external firmware loading during operation?
No. PTN3356BS/F1MP is flash-based and operates autonomously after power-up. Firmware version F1 is embedded in on-chip non-volatile memory, eliminating boot-time MCU dependency. Configuration pins (CFG1–CFG5) and AUX-accessible registers allow runtime tuning, but no external programming is needed for basic DP-to-VGA conversion functionality in PTN3356BS/F1MP.
How does PTN3356BS/F1MP handle VGA monitor hot-plug detection?
PTN3356BS/F1MP implements hardware-based load sensing on the RED/GRN/BLU analog outputs, pulsing each line to detect 75 Ω termination. When a VGA monitor is connected or disconnected, PTN3356BS/F1MP asserts or de-asserts the HPD signal and updates DPCD registers - enabling immediate source-side response without software polling or external circuitry.
Can PTN3356BS/F1MP drive 5 V HSYNC/VSYNC signals required by some legacy CRT monitors?
PTN3356BS/F1MP outputs 3.3 V HSYNC and VSYNC signals. To meet 5 V requirements of legacy CRTs or projectors, the reference design (Fig 4) includes optional buffer U3 (74LVC2G125DP) to level-shift these signals. This external buffer is not integrated into PTN3356BS/F1MP but is a validated, production-ready add-on in customer designs.
What power supply configuration is required for PTN3356BS/F1MP?
PTN3356BS/F1MP requires a single 3.3 V supply applied to VDDA33_DNW, VDDE33_IO, and PVDD33 pins. Internal switching regulator (SWOUT) generates 1.5 V rails for DP PHY (VDDA15_DP), DAC (VDDA15_DAC), and digital core (VDDD15). No external LDOs are needed unless using the optional LDO-mode variant shown in Fig 5 - PTN3356BS/F1MP defaults to DC-DC mode for optimal efficiency.
