NXP Semiconductors PTN3460BS/F2,518

Overview

PTN3460BS/F2,518 from NXP Semiconductors is an embedded DisplayPort (eDP) to LVDS bridge IC that converts high-speed eDP video streams into LVDS signals for driving TFT-LCD panels. It supports 1- or 2-lane eDP input at 1.62 Gbit/s or 2.7 Gbit/s, dual-bus LVDS output up to 112 MHz pixel clock, 24 bpp color depth, and on-chip EDID ROM emulation - enabling direct integration in notebook and AIO display subsystems.

For engineers reviewing the PTN3460BS/F2,518 datasheet, PTN3460BS/F2,518 pinout, PTN3460BS/F2,518 application, or PTN3460BS/F2,518 equivalent, key selection considerations include eDP v1.2 compliance, programmable LVDS bus configuration (VESA/JEIDA), firmware-controlled panel power sequencing, I²C- and AUX-based register access, and HVQFN56 thermal-enhanced packaging for space-constrained laptop mainboards.

Technical Context

The PTN3460BS/F2,518 implements a full eDP v1.2 receiver with Auto Receive Equalization, Fast/Full Link training, and support for ASSR and Enhanced Framing authentication. Its integrated CDR and Manchester codec recover timing from DP Main Link and convert stream data into parallel RGB+sync for LVDS transmission.

On the LVDS side, it delivers dual-bus operation with independent even/odd channel outputs, programmable swing (250–400 mV), center-spread clock modulation (32.9 kHz), and configurable data packing per VESA or JEIDA standards - all managed via DPCD registers, I²C-bus, or multi-level configuration pins.

FAQ

What display resolutions does the PTN3460BS/F2,518 support?

The PTN3460BS/F2,518 supports resolutions up to 1920×1200 @ 60 Hz in dual LVDS bus mode with 112 MHz pixel clock and 24 bpp. In single-bus mode, it supports 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 - all programmable via DPCD registers or configuration pins.

Does the PTN3460BS/F2,518 require an external crystal or clock source?

No, the PTN3460BS/F2,518 requires no external timing reference. It recovers pixel clock and timing directly from the incoming eDP Main Link using its integrated Clock Data Recovery (CDR) circuitry - eliminating BOM cost and board space for crystals, oscillators, or PLL components.

How does EDID emulation work on the PTN3460BS/F2,518?

The PTN3460BS/F2,518 contains on-chip non-volatile memory storing up to seven VESA EDID v1.3 structures. When an LVDS panel lacks an EDID ROM, the device responds to DDC read requests over AUX or I²C with preloaded EDID data - enabling GPU driver initialization without BIOS modification or external EEPROM.

Can the PTN3460BS/F2,518 operate with only a 3.3 V supply?

Yes, the PTN3460BS/F2,518 can operate with a single 3.3 V supply. Its integrated regulator generates the required 1.8 V core voltage. To use single-supply mode, leave EPS_N pin open or pull it HIGH; for dual-supply operation (3.3 V + 1.8 V), pull EPS_N LOW to disable the internal regulator.

What is the function of the HPDRX pin on the PTN3460BS/F2,518?

The HPDRX pin is a Hot Plug Detect output that signals readiness to the eDP source. It remains LOW during power-up and internal initialization, then transitions HIGH to indicate the PTN3460BS/F2,518 is ready to receive video - preventing false hot-plug events and ensuring synchronized link training with the GPU or chipset.
