PTN3460BS/F1,518

Overview

The PTN3460BS/F1,518 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 up to 112 MHz and supports color depths of 18 bpp or 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. The component is housed in a 56-terminal HVQFN package measuring 7 mm x 7 mm with a 0.4 mm pitch.

Feature Summary

• Embedded microcontroller and on-chip Non-Volatile Memory (NVM) enable flexible firmware updates via Flash-over-AUX.
• Supports EDID ROM emulation for panels lacking EDID ROM, accommodating up to seven different EDID data structures.
• Provides programmable LVDS signal swing and center spreading to minimize EMI and compensate for channel attenuation.
• Features integrated Auto Receive Equalization and Clock Data Recovery for optimal channel compensation.

Applications

• All-in-One (AIO) platforms
• Notebook platforms
• Netbooks and net tops

Procurement Notes

Verify the specific firmware version indicated by the suffix 'F1' against system requirements, as firmware versions are not necessarily backwards compatible. Confirm that the ordering label matches the required firmware revision. Ensure the procurement source provides documentation confirming the exact part marking and package specifications.

Selection Notes

Select this component when interfacing eDP sources with legacy LVDS displays. Consider the F1 firmware version specifically if previous versions caused compatibility issues. Evaluate power supply constraints to determine if the internal regulator (3.3 V only) or external 1.8 V supply is preferred. Verify that the target panel resolution fits within the 112 MHz pixel clock limit.

Part Context

This part belongs to the PTN3460 series of bridge ICs designed for commercial and industrial embedded applications. The 'BS' designation indicates the specific package type and temperature range, while the '/Fx' suffix denotes the firmware version programmed during manufacturing. Other variants exist with different firmware revisions or industrial temperature ratings.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Firmware-specific parts require matching firmware versions for direct replacement. Consult NXP technical support for alternative components if the current firmware version is incompatible with the host system.

FAQ

How does the PTN3460 handle panels without an EDID ROM?

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

What is the function of the PD_N pin?

The PD_N pin is a dedicated control input for Deep power-saving state. When driven LOW, it triggers a power-down sequence. To exit this state, the pin must be driven HIGH.

Can the PTN3460 operate with a single power supply?

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