Product details
Overview
PTN3393BS/F1Y from NXP Semiconductors is a DisplayPort v1.1a to VGA adapter IC integrating a 2-lane DisplayPort receiver and triple 8-bit DAC, supporting resolutions up to WUXGA (1920×1200 @ 60 Hz) with 240 MHz pixel clock, 700 mVpp analog RGB output into 75 Ω, and I²C-over-AUX for DDC/EDID bridging in dongle applications.
For engineers reviewing the PTN3393BS/F1Y datasheet, PTN3393BS/F1Y pinout, PTN3393BS/F1Y application, or PTN3393BS/F1Y equivalent, this device enables field-upgradable DP-to-VGA conversion with load-sensing monitor detection, HBR/RBR lane rate support (2.7/1.62 Gbit/s), and VESA VSIS 1.2-compliant analog video generation without external core regulators.
Technical Context
The PTN3393BS/F1Y implements a full DisplayPort v1.1a receiver with Main Link (1- or 2-lane, HBR/RBR), AUX channel (1 Mbit/s Manchester-II coded), DPCD register set (including SINK_COUNT and I²C speed control at 00109h), and integrated load-sensing circuitry for VGA monitor presence detection during vertical blanking. It bridges DDC traffic between source and sink using I²C-over-AUX syntax.
Its analog subsystem features three current-source DACs with RSET-controlled full-scale current (1.2 kΩ), generating HSYNC/VSYNC TTL outputs and 700 mVpp RGB signals compliant with double-terminated 75 Ω VGA cabling. Power sequencing is managed internally, with active-mode consumption of ~600 mW at UXGA and ~40 mW in low-power mode.

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 |
|---|---|---|---|
| ANX7411 | Single 27 MHz crystal-less architecture; integrated PLL eliminates external crystal; supports DP 1.2 but lacks Flash-over-AUX | Targeted at cost-sensitive consumer dongles where firmware field updates are not required | Choose ANX7411 when crystal BOM reduction outweighs need for post-deployment firmware upgrades |
| PS8315 | DP 1.1a compliant; 40-pin QFN; supports same resolutions but uses external 25 MHz crystal and lacks load-sensing monitor detect | Used in fixed-mount adapters where HPD is handled externally or omitted | Choose PS8315 when board layout already includes 25 MHz crystal and monitor detection is implemented at system level |
Compared with ANX7411 and PS8315, PTN3393BS/F1Y uniquely combines Flash-over-AUX upgradability, integrated 27 MHz crystal oscillator, and hardware-based VGA load sensing-making it optimal for certified, field-deployable dongles requiring robust monitor plug/unplug handling and firmware maintenance.

FAQ
What display resolutions does the PTN3393BS/F1Y support?
The PTN3393BS/F1Y supports all VESA-standard resolutions from VGA (640×480) to WUXGA (1920×1200) at 60 Hz, including UXGA (1600×1200 @ 162 MHz pixel clock) and SXGA (1280×1024 @ 108 MHz). Pixel clock rates up to 240 MHz are supported at 6 bits per color, and up to 180 MHz at 8 bits per color-limited only by the bandwidth of the upstream 2-lane DisplayPort link.
Does the PTN3393BS/F1Y require an external crystal oscillator?
Yes, the PTN3393BS/F1Y requires an external 27 MHz fundamental-mode crystal connected between OSC_IN and OSC_OUT pins, with two 20 pF load capacitors to ground. This crystal drives the on-chip PLL for precise pixel clock recovery and DAC timing-no crystal-less operation is supported.
How does monitor detection work on the PTN3393BS/F1Y?
The PTN3393BS/F1Y performs load sensing during vertical blanking intervals to detect 37.5 Ω (monitor connected) or 75 Ω (disconnected) termination on the VGA side. Upon detection, it updates DPCD register 00200h and asserts HPD with an IRQ pulse. Behavior is configurable via the S0 pin: tied HIGH enables conditional HPD assertion only when a monitor is present.
Can the PTN3393BS/F1Y drive standard VGA cables longer than 5 meters?
Yes-the PTN3393BS/F1Y is specified to drive up to 100 feet (~30.5 m) of analog VGA cable. Its 700 mVpp current-source RGB outputs maintain signal integrity over extended lengths, and its programmable I²C-over-AUX speed (down to 1 kbit/s) accommodates increased DDC bus capacitance in long-cable configurations.
What is the purpose of the RSET pin on the PTN3393BS/F1Y?
The RSET pin on the PTN3393BS/F1Y sets the full-scale current for all three 8-bit DACs. A 1.2 kΩ ±1 % resistor must be connected between RSET and analog ground to achieve the nominal 700 mVpp output amplitude into a doubly terminated 75 Ω VGA load-ensuring compliance with VSIS 1.2 analog video specifications.
