LM2502SM/NOPB

Overview

The LM2502SM/NOPB is a Mobile Pixel Link (MPL) display interface serializer manufactured by National Semiconductor. It converts parallel RGB data into a high-speed serial output stream for display applications. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 165 Mbps per lane. It features a 24-bit parallel input interface and utilizes a 28-pin SOIC package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Serializes parallel RGB video data into a differential LVDS-compatible serial stream
• Supports standard Mobile Pixel Link protocol for display panel interfacing
• Includes integrated clock recovery and data alignment logic

Applications

• Mobile phone LCD module interfaces
• Portable media player display drivers
• Embedded system visual output modules

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required lead-free and RoHS compliance status. Confirm the package type corresponds to the design footprint requirements before ordering.

Selection Notes

Select this component when a dedicated MPL serializer is required for low-power mobile displays. Compare pin compatibility with newer MPL-2 or MIPI alternatives if future-proofing is necessary. Verify that the serial output speed meets the target panel's timing specifications.

Part Context

This part belongs to the National Semiconductor Mobile Pixel Link family, designed to reduce trace count in portable devices. It serves as a bridge between application processors and display panels, replacing complex parallel bus architectures with a simplified serial connection.

Replacement Considerations

Check for direct pin-compatible upgrades such as the LM2502SQ/NOPB variant. Evaluate newer serializers like the LM4308 series for enhanced feature sets if system power consumption allows.
