Product details
Overview
PTN3356R1BSZ from NXP Semiconductors is a ROM-based DisplayPort-to-VGA adapter IC designed for motherboard-level video interface conversion, integrating a VESA-compliant DisplayPort 1.2a receiver and triple 8-bit DACs to deliver analog RGB output up to 240 MHz pixel clock (WUXGA @ 1920×1200, 60 Hz, 18 bpp), with 2-lane HBR/RBR support (2.7/1.62 Gbit/s per lane), I²C-over-AUX DDC bridging, and monitor presence detection via RGB load sensing.
For engineers reviewing the PTN3356R1BSZ datasheet, PTN3356R1BSZ pinout, PTN3356R1BSZ application, or PTN3356R1BSZ equivalent, key selection criteria include DP-to-VGA protocol translation fidelity, VGA output compliance with VSIS 1.2, low-power operation (~200 mW active, 410 µW standby), HPD signaling behavior, and compatibility with standard 75 Ω doubly terminated VGA loads.
Technical Context
The PTN3356R1BSZ implements full DisplayPort 1.2a physical layer reception-including CDR, auto-equalization, and Manchester-II AUX channel decoding-with native support for eDP extensions (ASSR, Enhanced Framing). Its digital subsystem extracts main stream video attributes during vertical blanking and reconstructs timing using recovered clock data.
It bridges the DisplayPort AUX channel to the VGA-side DDC bus using standardized I²C-over-AUX protocol conversion, enabling EDID access by the source while reporting sink status changes via HPD IRQ and DPCD register updates-without caching or modifying EDID content.

Applications

|---|---|
Use Scenario: Integrated DP-to-VGA conversion on ATX/mATX motherboard PCBs where legacy VGA header must coexist with modern GPU DP outputs. IC Role / Device Role / Timing Role: Protocol translator and timing reconstructor-extracts video attributes from DP main stream, recovers pixel clock, drives analog sync and RGB signals synchronized to source timing. Use Value: Eliminates need for discrete level shifters, external clock generators, or FPGA-based conversion logic; reduces BOM count and layout complexity. |
Use Scenario: Embedded in USB-C or proprietary docking stations to provide VGA output alongside HDMI/USB while sharing single DP Alt Mode lane. IC Role / Device Role / Timing Role: DP sink with VGA source emulation-accepts DP link training, responds to DPCD reads, and presents EDID to host while driving analog VGA signals. Use Value: Enables plug-and-play VGA monitor support without firmware intervention; maintains hot-plug detection across dock attach/detach cycles. |
| Embedded Industrial Panel PC | Legacy Monitor Upgrade Module |
Use Scenario: Retrofitting older industrial displays with VGA input into DP-based control systems where display replacement is cost-prohibitive. IC Role / Device Role / Timing Role: Signal integrity-preserving bridge-performs auto-receive equalization and CDR to recover clean DP data even over long or lossy traces. Use Value: Extends usable life of installed VGA monitors in automation systems; avoids EMI-prone active cable solutions. |
Use Scenario: Standalone adapter module (e.g., DP male to VGA female) with minimal external components for consumer electronics OEMs. IC Role / Device Role / Timing Role: Self-contained converter-integrates oscillator, DACs, HPD logic, and DDC bridge in single HVQFN package; requires only RSET and decoupling caps. Use Value: Reduces adapter bill-of-materials to <5 passive components; simplifies CE/FCC emissions testing by minimizing high-speed routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DisplayPort-to-VGA conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S016 | Integrated ESD protection (±15 kV contact), no internal DAC-requires external triple DAC and sync drivers | Targeted at DP source-side protection + level shifting; not a full protocol converter | Select when system already includes DAC and timing reconstruction circuitry; not drop-in for PTN3356R1BSZ's end-to-end conversion role |
| Parade PS8315 | Supports DP 1.4, higher pixel clock (340 MHz), but requires external oscillator and lacks integrated load-sensing HPD | Optimized for high-resolution embedded displays (e.g., medical panels); no VGA monitor detection logic | Choose for >240 MHz pixel rates or DP 1.4 compliance; add external GPIO-based HPD if VGA plug detection is required |
Compared with TPD12S016 and PS8315, PTN3356R1BSZ delivers complete, self-contained DP-to-VGA conversion-including DAC, sync generation, EDID passthrough, and hardware-based monitor detection-in a single chip with minimal external components, making it optimal for cost-sensitive motherboard and dongle designs requiring VESA 1.2a compliance and low standby power.

FAQ
What is the maximum supported pixel clock rate for PTN3356R1BSZ?
The PTN3356R1BSZ supports up to 240 MHz pixel clock at 18 bits per pixel (bpp), enabling WUXGA (1920×1200, 60 Hz) and 2.76M3 (1920×1440, 60 Hz) resolutions. At 24 bpp, the limit is 180 MHz due to 2-lane DP v1.2a bandwidth constraints. This is confirmed in Table 8 and Section 2.4 of the official datasheet.
Does PTN3356R1BSZ require an external crystal oscillator?
Yes, PTN3356R1BSZ requires an external 24 MHz, 25 MHz, or 27 MHz crystal or ceramic resonator connected between OSC_IN (pin 25) and OSC_OUT (pin 26). The CFG5 pin selects the frequency: HIGH = 24 MHz, LOW = 25 MHz, OPEN = 27 MHz-as specified in Table 5 of the datasheet.
How does PTN3356R1BSZ handle VGA monitor detection?
PTN3356R1BSZ performs periodic load sensing on the RED, GRN, and BLU analog outputs to detect presence of a 75 Ω termination. When a VGA monitor is disconnected, it asserts HPD IRQ and updates DPCD registers to notify the DP source-enabling automatic display disable without software polling.
Can PTN3356R1BSZ operate with only one DisplayPort lane?
Yes, PTN3356R1BSZ supports both 1-lane and 2-lane DisplayPort Main Link configurations at either RBR (1.62 Gbit/s) or HBR (2.7 Gbit/s) per lane. Lane count is auto-detected during link training; no configuration pin or register setting is required to enable 1-lane mode.
What is the function of the RSET pin on PTN3356R1BSZ?
The RSET pin (pin 23) accepts a 1.2 kΩ ±1% resistor to ground, which sets the reference current for the triple 8-bit DACs. This ensures precise 700 mVPP analog output amplitude into a 37.5 Ω load-matching the standard doubly terminated 75 Ω VGA interface requirement per VSIS 1.2.
