LM2506SQ/NOPB

Overview

The LM2506SQ/NOPB is a high-speed serializer/deserializer (SerDes) manufactured by National Semiconductor. It operates at data rates up to 320Mbps and features 22 serial inputs with 3 parallel outputs, or alternatively configured as 3 serial inputs with 22 parallel outputs. The device is housed in a 40-WQFN (5x5 mm) package designed for surface-mount applications.

Feature Summary

Supports high-speed data serialization and deserialization at 320Mbps
Configurable input/output mapping between serial and parallel interfaces
Compact 40-pin WQFN package suitable for space-constrained designs

Applications

High-speed digital signal transmission systems
Parallel-to-serial interface conversion modules
Serial-to-parallel data distribution networks

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific pinout configuration matches the required 22/3 or 3/22 I/O mapping. Ensure the 40-WQFN footprint dimensions align with the PCB layout specifications before ordering.

Selection Notes

Select this component when a fixed 320Mbps SerDes capability is required. Evaluate the trade-off between the 40-pin package size and the high I/O count. Consider thermal dissipation requirements associated with the QFN package in dense circuit layouts.

Part Context

This part belongs to the LM2506 series of serializers and deserializers. It serves as an interface bridge between parallel processing units and serial communication lines, facilitating efficient data transfer in electronic systems requiring high bandwidth over limited trace counts.

Replacement Considerations

Check for direct equivalents within the LM2506 family from Texas Instruments. Verify pin compatibility and electrical characteristics against alternative SerDes devices if sourcing from different manufacturers.
