PTN3460IBS/F2MP

Overview

The PTN3460IBS/F2MP is an Embedded DisplayPort to LVDS bridge IC designed for industrial and embedded applications. It converts DP streams from CPUs or GPUs into LVDS signals for display panels, supporting link rates of 1.62 Gbit/s and 2.7 Gbit/s with one or two lanes. The device handles pixel clocks up to 112 MHz in single or dual bus modes, accommodating 18-bit or 24-bit color depths. It features an embedded microcontroller and Non-Volatile Memory (NVM) for firmware updates, EDID ROM emulation, and operates within a temperature range of -40°C to +85°C. Powered by 3.3 V or dual supplies (3.3 V/1.8 V), it is housed in a 56-terminal HVQFN package.

Feature Summary

• Embedded microcontroller and on-chip Non-Volatile Memory enable flexible firmware updates without external components.
• Supports EDID ROM emulation to accommodate LVDS panels lacking physical EDID memory, configurable via specific control pins.
• Provides programmable panel power-up sequencing and backlight control through dedicated output pins.
• Integrates high-performance auto receive equalization and clock data recovery for optimal signal integrity across varying channel environments.

Applications

• Industrial PC design
• Automotive dashboard displays
• All-in-one (AIO) platforms

Procurement Notes

Verify the suffix 'F2' corresponds to the required firmware version, as different firmware revisions are not necessarily backwards compatible. Confirm the orderable part number includes the MP suffix for reel packaging. Ensure the application environment supports the specified operating temperature range and voltage requirements before finalizing procurement.

Selection Notes

Select this component when interfacing eDP sources with legacy LVDS panels in industrial or automotive contexts requiring wide temperature tolerance. Consider the F2 firmware version specifically if previous versions exhibited compatibility issues with certain display timings or EDID structures. Evaluate the need for EDID emulation features if the target panel lacks onboard memory.

Part Context

This part belongs to the PTN3460I family of bridge controllers manufactured by NXP Semiconductors. The IB designation indicates the industrial temperature grade variant. The F2 suffix specifies the pre-loaded firmware version on the internal non-volatile memory, which dictates specific operational behaviors and bug fixes compared to other firmware revisions like F1 or F6.

Replacement Considerations

PTN3460IBS/Fx serves as a functional replacement for Analogix ANX9804B series devices in similar bridge applications. When substituting, verify that the pinout compatibility and firmware configuration options align with the existing system design constraints.

FAQ

What does the 'F2' suffix indicate in the part number?

The 'F2' suffix indicates that the device is loaded with firmware version 2. Firmware versions are specific to the part and may not be backwards compatible with other versions.

Can the PTN3460IBS/F2MP operate without an external EDID ROM on the display panel?

Yes, the device supports EDID ROM emulation. This feature can be enabled via the CFG4 configuration pin to support panels that do not have an onboard EDID EEPROM.

Is the PTN3460IBS/F2MP suitable for automotive applications?

Yes, the PTN3460I variant is explicitly designed for industrial and embedded applications, including automotive dashboard displays, with an operating temperature range of -40°C to +85°C.
