PTN3460BS,518

Overview

The PTN3460BS is an embedded DisplayPort to LVDS bridge IC manufactured by NXP Semiconductors. It converts DP streams from CPU/GPU sources into LVDS format for display panels. The device supports 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, supporting single or dual bus LVDS signaling with 18-bit or 24-bit color depths. Power supplies include 3.3 V (±10%) and 1.8 V (±5%). Operating temperature ranges from -40 °C to +85 °C. The component is housed in a 56-terminal HVQFN package measuring 7 mm x 7 mm.

Feature Summary

• Embedded microcontroller and on-chip Non-Volatile Memory enable flexible firmware updates.
• Supports EDID ROM emulation for panels lacking EDID ROM, accommodating up to seven data structures.
• Provides programmable LVDS signal swing and center spreading to minimize EMI and compensate for channel attenuation.
• Integrates 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 suffix required for the application, as versions are not necessarily backwards compatible. Confirm power supply configuration options, specifically whether the internal regulator will be used or if dual supplies are needed. Ensure the PCB layout accommodates the exposed center pad for thermal relief and electrical grounding.

Selection Notes

Select based on the required link rate and lane count compatibility with the source GPU or CPU. Evaluate the need for EDID emulation features if the target panel lacks non-volatile memory. Consider the operating temperature range requirements for the specific deployment environment. Verify that the host system supports the necessary I2C-bus or AUX interface protocols for configuration.

Part Context

The PTN3460 series serves as a bridge between Embedded DisplayPort sources and LVDS displays. It replaces discrete translation components by integrating protocol conversion, equalization, and control logic into a single chip. This integration reduces board space and simplifies design complexity for portable computing devices requiring high-resolution displays.

Replacement Considerations

PTN3460IBS/F1MP is a documented industrial-grade variant within the same family. Verify pinout and firmware compatibility before substitution. Other models in the PTN3460 series may differ in firmware or environmental ratings.
