PTN3460IBS/F1MP

Overview

The PTN3460IBS/F1MP is an embedded DisplayPort to LVDS bridge IC manufactured by NXP Semiconductors. It converts DP streams from sources like CPUs or GPUs into LVDS format for display panels. The device supports Main Link rates of 1.62 Gbit/s and 2.7 Gbit/s with 1-lane or 2-lane operation. It handles pixel clock frequencies from 6 MHz to 112 MHz, supporting color depths of 18 bpp and 24 bpp in single or dual LVDS bus modes. Power supply options include a single 3.3 V rail or dual 3.3 V/1.8 V rails. It operates within a temperature range of -40 °C to +85 °C and is housed in a HVQFN56 package.

Feature Summary

• Embedded microcontroller and on-chip Non-Volatile Memory enable flexible firmware updates and configuration.
• Supports EDID ROM emulation to accommodate display panels lacking physical EDID memory.
• Provides programmable LVDS signal swing and center spreading to minimize EMI and compensate for channel attenuation.
• Features high-performance Auto Receive Equalization and integrated termination resistors for optimal signal integrity.

Applications

• Industrial PC design
• Automotive dashboard display
• All-in-One (AIO) platforms

Procurement Notes

Verify the specific firmware version associated with the F1 suffix before procurement, as firmware versions are not necessarily backwards compatible. Confirm that the ordering label indicates the correct firmware revision corresponding to the part number. Ensure the application environment meets the specified operating temperature range and power supply requirements for proper device initialization and operation.

Selection Notes

Select this component when interfacing eDP sources with legacy LVDS panels in industrial or embedded environments requiring wide temperature tolerance. Consider the available configuration methods, including multi-level pins, DP AUX interface, and I2C-bus interface, to determine the best fit for system architecture. Evaluate whether single or dual LVDS bus modes are necessary based on the target resolution and color depth requirements.

Part Context

The PTN3460I series serves as a bridge solution for converting Embedded DisplayPort signals to Low-Voltage Differential Signaling. It is designed for applications where direct eDP-to-LVDS connectivity is required without replacing existing panel infrastructure. The device integrates protocol conversion, link training, and panel control features into a compact package suitable for space-constrained embedded designs.

FAQ

How does the PTN3460IBS/F1MP handle panels without EDID ROM?

The device supports EDID ROM emulation, allowing it to mimic EDID behavior for panels that lack physical EDID memory. This feature avoids the need for specific changes in the system video BIOS.

What are the supported data formats for LVDS output?

The PTN3460I supports RGB data packing in both VESA and JEIDA formats. The specific format can be configured via multi-level configuration pins or through the register interface.

Can the PTN3460IBS/F1MP operate with a single power supply?

Yes, the device can be powered by a single 3.3 V supply with the internal regulator switched on. Alternatively, it supports dual supplies of 3.3 V and 1.8 V if the internal regulator is disabled.
