Product details
Overview
PTN3392BS/F1,518 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 with triple 8-bit DACs, supporting resolutions up to WUXGA (1920×1200 @ 60 Hz, 154 MHz pixel clock) and VSIS 1.2 compliance. It integrates DisplayPort receiver, DDC bridging, HPD signaling, and load-sensing monitor detection for PC dongles and docking stations.
For engineers reviewing the PTN3392BS/F1,518 datasheet, PTN3392BS/F1,518 pinout, PTN3392BS/F1,518 application, or PTN3392BS/F1,518 equivalent, key selection considerations include its 48-pin HVQFN package, 3.3 V single-supply operation, Flash-over-AUX firmware upgradability, I²C-over-AUX support for DDC-CI/MCCS, and configurable I²C speed (100 kbit/s default for this variant).
Technical Context
The PTN3392BS/F1,518 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 timing for DAC conversion.
It features integrated DPCD registers (e.g., 00109h for I²C speed control), supports native AUX CH syntax and I²C-bus over AUX CH, and bridges sink-side DDC (SCL/SDA) to source-side AUX with defer response handling. Monitor presence detection uses active load sensing during vertical blanking only, updating DPCD SINK_COUNT and generating HPD IRQ without screen disturbance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main Link Lanes | 1 or 2 lanes - enables flexible bandwidth allocation for VGA resolutions from VGA to WUXGA |
| Data Rate per Lane | 1.62 Gbit/s (RBR) or 2.7 Gbit/s (HBR) - determines maximum supported pixel clock (up to 240 MHz) |
| DAC Resolution | Triple 8-bit - delivers 256-level grayscale per RGB channel, compatible with standard VGA analog levels |
| Pixel Clock Max | 240 MHz - supports WUXGA with reduced blanking and UXGA at full rate |
| I²C Speed Default | 100 kbit/s - set by S2 pin configuration and reflected in DPCD register 00109h reset value |
| Supply Voltage | 3.3 V ±10 % - powers all domains (VDDD, VDDA, VDDA_DP, VDD_IO, VDD_DAC) from single rail |
| Package | HVQFN48, 7 mm × 7 mm × 0.85 mm, 0.5 mm pitch - thermal-enhanced lead-free package with exposed pad |
| Operating Temp | 0 °C to +85 °C - qualified for commercial desktop, notebook, and docking station environments |
Pinout & Package
PTN3392BS/F1,518 is housed in a 48-pin HVQFN (SOT619-1) package with 7 mm × 7 mm footprint, 0.5 mm pitch, and thermally enhanced exposed center pad requiring PCB thermal vias. Power domains are segregated: VDDD/VDDA/VDDA_DP/VDD_IO/VDD_DAC supply pins, dedicated analog/digital grounds (GNDD/GND_IO/GND_DAC/GNDA_DP0/GNDA_DP1/GNDA), and differential DisplayPort lanes (ML0_P/N, ML1_P/N) and AUX (AUX_P/N).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDD (31,32) | Digital core supply | 3.3 V power for logic, DPCD, and control subsystems; requires local 0.1 µF decoupling |
| ML0_P/N (43,44) | Main Link Lane 0 differential input | AC-coupled DP lane; internal 50 Ω termination eliminates external resistors |
| AUX_P/N (39,40) | AUX channel differential I/O | Manchester-II encoded 1 MHz bidirectional channel for DPCD and DDC bridging |
| RSET (22) | DAC reference current control | Connects to GND_DAC via 1.2 kΩ ±1 % resistor to set 700 mVpp output into 37.5 Ω load |
| HPD (3) | Hot-plug detect output | 3.3 V TTL signal reporting sink connection status; behavior configurable via S0 pin |
| S2 (35) | I²C speed strap input | Pull-down = 100 kbit/s default (for PTN3392BS/F1,518); pull-up = 10 kbit/s; sets DPCD 00109h reset value |
Key Features
| Feature | Design Value |
|---|---|
| Flash-over-AUX field upgradability | Enables firmware updates without physical access or dedicated programming interface |
| VESA DDC bridging with I²C-over-AUX | Supports full DDC-CI and MCCS protocols by translating AUX transactions to SCL/SDA signals |
| Load-sensing monitor detection | Detects 37.5 Ω vs. 75 Ω termination during vertical blanking only - no image artifacts |
| Configurable HPD behavior | S0 pin selects between v1.1a-compliant (HPD always asserted post-init) or sink-aware (HPD tracks monitor presence) |
| Single 3.3 V supply operation | Eliminates need for separate core voltage regulator; powered directly from DP_PWR pin |
| VSIS 1.2–compliant analog outputs | RGB current-source outputs drive double-terminated 75 Ω cables directly at 700 mVpp |

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 | Integrated level-shifting and ESD protection for DDC lines; no DAC or video conversion - requires external VGA DAC | Targeted at DP-to-HDMI/VGA *re-timers* with external signal path; not a full adapter IC | Select when adding robust DDC buffering to existing adapter designs, not as standalone replacement |
| Parade PS8315 | Supports DP 1.2 (5.4 Gbit/s/lane), higher resolution (4K@30), but requires external crystal and lacks Flash-over-AUX | Designed for newer DP sources and higher-resolution displays; no native VGA DAC - outputs LVDS or eDP | Choose for DP 1.2 compatibility and future-proofing; not drop-in for PTN3392BS/F1,518's VGA-native use case |
Compared with TI TPD12S016 and Parade PS8315, PTN3392BS/F1,518 uniquely integrates full DisplayPort v1.1a receiver, triple 8-bit DAC, DDC bridge, and monitor detection in a single 48-pin HVQFN - eliminating external components required by alternatives and enabling compact, cost-optimized VGA dongles.

FAQ
What is the default I²C speed setting for PTN3392BS/F1,518?
The PTN3392BS/F1,518 defaults to 100 kbit/s I²C speed, as determined by the S2 pin being pulled low (internal pull-down) and reflected in DPCD register 00109h power-on reset value. This setting supports standard DDC communication with most VGA monitors and enables full DDC-CI and MCCS functionality without requiring source-side speed negotiation.
Does PTN3392BS/F1,518 require an external crystal oscillator?
Yes, PTN3392BS/F1,518 requires an external 27 MHz crystal connected between OSC_IN (pin 26) and OSC_OUT (pin 27). The on-board crystal oscillator circuit uses this reference to generate internal clocks for DAC timing and AUX channel operation; no internal RC oscillator is provided.
How does PTN3392BS/F1,518 handle monitor hot-plug detection?
PTN3392BS/F1,518 performs active load sensing during vertical blanking intervals to detect 37.5 Ω (monitor connected) vs. 75 Ω (disconnected) termination. Upon change, it updates DPCD SINK_COUNT register and asserts HPD IRQ to notify the DisplayPort source - all without visible screen disturbance.
Can PTN3392BS/F1,518 support resolutions beyond WUXGA?
No, PTN3392BS/F1,518 supports resolutions up to WUXGA (1920×1200) at 60 Hz with reduced blanking (154 MHz pixel clock) or full blanking (193 MHz), limited by its 240 MHz max pixel clock and dual-lane DP v1.1a bandwidth. Higher resolutions like QXGA or 4K exceed its DAC and link capability.
What is the purpose of the RSET pin on PTN3392BS/F1,518?
The RSET pin (pin 22) sets the full-scale current for the triple 8-bit DACs. A 1.2 kΩ ±1 % resistor must be connected from RSET to GND_DAC to establish 700 mV peak-to-peak analog RGB output into a 37.5 Ω load - matching standard doubly terminated 75 Ω VGA cabling requirements.
