Product details
Overview
PTN3392BS/F3,518 from NXP Semiconductors is a VESA DisplayPort v1.1a-compliant adapter IC that converts 1- or 2-lane DisplayPort signals (1.62/2.7 Gbit/s per lane) into analog VGA output via triple 8-bit DACs, supporting resolutions up to WUXGA (1920×1200 @ 60 Hz, 154 MHz pixel clock) and VSIS 1.2 compliance. It integrates a DisplayPort receiver, DDC bridge, HPD signaling, and load-sensing monitor detection for PC-to-VGA dongles and docking stations.
For engineers reviewing the PTN3392BS/F3,518 datasheet, PTN3392BS/F3,518 pinout, PTN3392BS/F3,518 application, or PTN3392BS/F3,518 equivalent, key selection criteria include its 2-lane DP-to-VGA conversion capability, Flash-over-AUX firmware upgradability, I2C-bus speed control via DPCD register 00109h (default 50 kbit/s for this variant), and HVQFN48 package with integrated termination and 3.3 V single-supply operation.
Technical Context
The PTN3392BS/F3,518 implements a full DisplayPort v1.1a receiver with CDR-based main link recovery for 1- or 2-lane operation at RBR (1.62 Gbit/s) or HBR (2.7 Gbit/s), plus Manchester-II encoded AUX channel handling at 1 MHz. Its digital subsystem extracts video attributes during vertical blanking and reconstructs RGB timing using recovered clock and stream data.
It bridges the DisplayPort AUX channel to the VGA-side DDC bus, enabling I2C-bus over AUX for MCCS, DDC-CI, and standard DDC protocols. Monitor presence detection uses active load sensing during vertical blanking only, updating DPCD registers 00200h/00204h and generating HPD IRQ without screen disturbance.

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 | Single-lane DP receiver only; no native 2-lane support; lower max pixel clock (165 MHz); requires external crystal | Limited to XGA/SXGA; not suitable for WUXGA or UXGA at 60 Hz; lacks Flash-over-AUX capability | Select when cost-sensitive, lower-resolution applications dominate and firmware updates are infrequent |
| Parade PS8315 | Supports DP 1.2; includes integrated HDCP engine; higher power consumption (~850 mW active); different pinout and package (QFN56) | Targets premium dongles requiring content protection; adds HDCP 1.3/2.2 compliance not present in PTN3392BS/F3,518 | Select when HDCP enforcement is mandatory and DP 1.2 link robustness outweighs footprint and power constraints |
Compared with TI TPD12S016 and Parade PS8315, the PTN3392BS/F3,518 offers balanced 2-lane DP v1.1a support, field-upgradable firmware, and minimal BOM count-making it optimal for cost-constrained, high-volume VGA dongles where WUXGA timing and VESA compliance are essential but HDCP is unnecessary.

FAQ
What is the default I2C-bus speed for PTN3392BS/F3,518 and how is it configured?
The PTN3392BS/F3,518 defaults to 50 kbit/s I2C-bus speed, determined by the S2 pin configuration (internal pull-down) and reflected in DPCD register 00109h at power-on reset. This setting is explicitly documented for firmware version F3 in Table 4 of the datasheet and enables reliable DDC communication over extended VGA cabling without requiring source-side speed negotiation.
Does PTN3392BS/F3,518 support both 1-lane and 2-lane DisplayPort configurations?
Yes, PTN3392BS/F3,518 supports both 1-lane and 2-lane DisplayPort v1.1a main link operation at either 1.62 Gbit/s (RBR) or 2.7 Gbit/s (HBR) per lane. The lane count is negotiated dynamically during link training, and the IC adapts its internal clock recovery and data path accordingly-enabling flexible use across DP sources with varying lane capabilities.
How does PTN3392BS/F3,518 handle monitor detection and HPD signaling?
PTN3392BS/F3,518 performs active load sensing during vertical blanking intervals to detect 37.5 Ω (monitor connected) versus 75 Ω (disconnected) termination. It reports status via DPCD registers 00200h/00204h and generates HPD IRQ pulses. HPD output behavior is controlled by the S0 pin: LOW forces constant HPD assertion; HIGH makes HPD state conditional on detected monitor presence.
What is the role of the RSET pin on PTN3392BS/F3,518 and what resistor value is required?
The RSET pin on PTN3392BS/F3,518 sets the full-scale current for the triple 8-bit DACs by connecting an external 1.2 kΩ ±1 % resistor to analog ground. This establishes the 700 mVpp analog RGB output amplitude into a doubly terminated 75 Ω VGA load-ensuring VSIS 1.2 compliance and eliminating need for external amplification or level shifting.
Is PTN3392BS/F3,518 compatible with DisplayPort sources that implement HDCP?
No, PTN3392BS/F3,518 does not implement HDCP encryption or decryption. It functions as a transparent protocol converter: encrypted DP streams pass through unchanged, but downstream VGA monitors cannot decode HDCP-protected content. For HDCP-compliant applications, a separate HDCP repeater or alternative IC such as Parade PS8315 must be used alongside PTN3392BS/F3,518.
