NXP Semiconductors PTN3460BS/F6Y

Overview

PTN3460BS/F6Y 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 VESA/JEIDA data packing - enabling 1920×1200@60 Hz resolution in notebook and AIO display interfaces.

For engineers reviewing the PTN3460BS/F6Y datasheet, PTN3460BS/F6Y pinout, PTN3460BS/F6Y application, or PTN3460BS/F6Y equivalent, key selection considerations include eDP v1.2 compliance, on-chip EDID emulation, firmware-configurable LVDS bus topology, panel power sequencing control via PVCCEN/BKLTEN/PWMO, and HVQFN56 package compatibility with high-density motherboard layouts.

Technical Context

The PTN3460BS/F6Y implements a full eDP v1.2 receiver with Auto Receive Equalization, Clock Data Recovery (CDR), and support for Fast/Full Link Training - enabling robust signal integrity across variable PCB trace lengths. Its dual-bus LVDS transmitter delivers up to 224 mega pixels per second using programmable channel swapping, differential pair inversion, and center-spread clock modulation (32.9 kHz).

System-level flexibility is achieved through three concurrent configuration paths: multi-level hardware pins (CFG1–CFG4), DP AUX channel register access (DPCD vendor region 0x00510h), and I2C-bus slave interface (100/400 kbit/s). The embedded microcontroller and on-chip NVM allow field-updatable firmware without external memory.

FAQ

What display resolutions does the PTN3460BS/F6Y support?

The PTN3460BS/F6Y supports up to 1920×1200@60 Hz in dual LVDS bus mode with 24 bpp color depth 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), pixel clock frequency, and LVDS bus mode - all programmable via DPCD registers or hardware pins. The PTN3460BS/F6Y datasheet specifies exact timing margins for each configuration.

Does PTN3460BS/F6Y require an external crystal or clock source?

No, the PTN3460BS/F6Y does not require an external crystal or clock source. It uses an integrated PLL and Clock Data Recovery (CDR) circuit to extract timing directly from the incoming eDP Main Link stream. This eliminates the need for external oscillators, reduces BOM cost, and simplifies PCB layout - a key advantage over competing bridges requiring separate clock generators. The PTN3460BS/F6Y achieves stable LVDS clock synthesis solely from the eDP signal.

How does PTN3460BS/F6Y handle panels without EDID ROM?

The PTN3460BS/F6Y implements on-chip EDID ROM emulation supporting VESA EDID structure v1.3 and up to seven distinct EDID data sets. When connected to a panel lacking EDID, the PTN3460BS/F6Y responds to DDC read requests with preloaded EDID data - eliminating the need for external EEPROM or BIOS modifications. This feature is enabled by default and configurable via DPCD vendor registers, ensuring seamless plug-and-play operation with diverse LVDS panels.

Can PTN3460BS/F6Y be configured via I2C-bus instead of DP AUX?

Yes, the PTN3460BS/F6Y supports configuration via I2C-bus in addition to DP AUX. The DEV_CFG pin (pin 12) selects I2C address mode: pull-down for 0x40h, open for 0xC0h, or pull-up for master mode. The I2C interface operates at Standard-mode (100 kbit/s) or Fast-mode (400 kbit/s), allowing full register access independent of eDP link status - useful during system initialization or debug. All PTN3460BS/F6Y configuration registers accessible via AUX are also available over I2C.

What is the function of the EPS_N pin on PTN3460BS/F6Y?

The EPS_N pin on PTN3460BS/F6Y selects the power supply configuration: pulled HIGH (or left open) enables single 3.3 V supply with internal 1.8 V regulator active; pulled LOW connects the device to external 1.8 V supply for dual-rail operation. This pin determines whether the internal regulator powers the 1.8 V domain (VDD(1V8) output at pin 19) or bypasses it. Correct EPS_N biasing is essential to avoid regulator conflict and ensure stable LVDS PHY operation in the PTN3460BS/F6Y.
