Product details
Overview
PTN3460BS,518 from NXP Semiconductors is an embedded DisplayPort (eDP) to LVDS bridge IC that converts DP v1.2/eDP v1.2 video streams into dual-bus or single-bus LVDS output for TFT-LCD panels. It supports 1- or 2-lane DP input at 1.62 Gbit/s or 2.7 Gbit/s, LVDS pixel clock up to 112 MHz, 18/24 bpp color depth, and on-chip EDID ROM emulation. It enables direct integration in notebook and AIO platforms requiring high-resolution panel interfacing without external timing references.
For engineers reviewing the PTN3460BS,518 datasheet, PTN3460BS,518 pinout, PTN3460BS,518 application, or PTN3460BS,518 equivalent, key selection considerations include DP-to-LVDS protocol conversion fidelity, firmware-configurable LVDS bus mapping (VESA/JEIDA), eDP authentication support (ASSR/Enhanced Framing), and dual-supply (3.3 V/1.8 V) or single-supply (3.3 V only) operation with HVQFN56 thermal pad grounding.
Technical Context
The PTN3460BS,518 implements a full DisplayPort receiver with Auto Receive Equalization, Clock Data Recovery (CDR), and native AUX/I2C-over-AUX transaction handling for DPCD register access and EDID-DDC communication. Its LVDS transmitter supports programmable center-spread clock modulation (32.9 kHz), differential pair swapping, and configurable swing (250–400 mV) for EMI reduction and channel compensation.
System-level control is enabled via three configuration methods: multi-level hardware pins (CFG1–CFG4), I2C-bus slave interface (100/400 kbit/s), and DP AUX channel. The embedded microcontroller and on-chip NVM allow field-updatable firmware, while Deep Power-down (PD_N) and reset (RST_N) pins provide deterministic power-state management aligned with eDPv1.2 panel sequencing requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar eDP-to-LVDS bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CH7511B-DS | Supports DP 1.1a only; no eDP v1.2 authentication (ASSR/Enhanced Framing); fixed 24 bpp LVDS output | Limited to legacy DP sources; lacks EDID emulation-requires external EEPROM | Choose when cost sensitivity outweighs eDP compliance and firmware update capability |
| PS8315-SP | Supports DP 1.2 but no eDP v1.2 features; no on-chip NVM or EDID emulation; requires external clock source | Suitable for non-eDP DP sources only; no panel power sequencing control via DPCD | Select only if design uses discrete DP (not eDP) and external timing reference is acceptable |
Compared with CH7511B-DS and PS8315-SP, the PTN3460BS,518 delivers full eDP v1.2 compliance, firmware-upgradable behavior, and autonomous EDID handling-making it the only option for modern notebook platforms requiring ASSR authentication and BIOS-agnostic panel bring-up.

FAQ
What display resolutions does the PTN3460BS,518 support?
The PTN3460BS,518 supports up to 1920×1200@60 Hz in dual LVDS bus mode with 24 bpp and 112 MHz pixel clock. In single-bus mode, it supports resolutions up to 1366×768@60 Hz. Resolution capability depends on configured lane count (1 or 2), color depth (18/24 bpp), and LVDS bus mode-verified per VESA and JEIDA data packing formats defined in the PTN3460BS,518 datasheet.
Does the PTN3460BS,518 require an external crystal or clock source?
No, the PTN3460BS,518 does not require an external crystal or clock source. It integrates a high-performance Clock Data Recovery (CDR) circuit and internal timing recovery logic that extracts pixel clock and synchronization signals directly from the incoming DisplayPort stream-enabling fully self-contained operation as specified in the PTN3460BS,518 product data sheet.
How is EDID handled on the PTN3460BS,518 when the LVDS panel lacks an EDID ROM?
The PTN3460BS,518 provides on-chip EDID ROM emulation supporting up to seven preloaded VESA EDID v1.3 structures. When the connected LVDS panel has no EDID ROM, the PTN3460BS,518 automatically responds to DDC read requests from the eDP source using the selected emulated structure-eliminating BIOS modifications and enabling true plug-and-play panel compatibility.
Can the PTN3460BS,518 operate with only a 3.3 V supply?
Yes, the PTN3460BS,518 can operate with a single 3.3 V supply. In this configuration, the internal regulator generates the required 1.8 V rail, and the EPS_N pin must be left open or pulled HIGH. Dual-supply operation (3.3 V + 1.8 V) is also supported when EPS_N is pulled LOW-providing design flexibility for power architecture optimization in the PTN3460BS,518 implementation.
What configuration interfaces does the PTN3460BS,518 support for runtime programming?
The PTN3460BS,518 supports three configuration interfaces: multi-level hardware pins (CFG1–CFG4) for boot-time setup, DP AUX channel for DPCD register access by GPU firmware, and I2C-bus interface (100/400 kbit/s) with selectable slave addresses (0x40h or 0xC0h) via DEV_CFG pin-enabling flexible integration across BIOS, driver, and hardware layers in the PTN3460BS,518 system design.
