DS40MB200SQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS40MB200SQ/NOPB is a dual-channel multiplexer and buffer manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 4.0 Gbps with CML input and output signaling. The device integrates transmit pre-emphasis and receive equalization to enhance signal integrity over lossy channels. It operates within a supply voltage range of 3.135 V to 3.465 V and functions across an industrial temperature range from -40°C to +85°C. Packaged in a 48-pin WQFN (7x7 mm) format, it provides two independent 2:1 or 1:2 mux/buffer channels.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates dual channels capable of operating as either 2:1 multiplexers or 1:2 demultiplexers.
• Includes programmable transmit pre-emphasis to compensate for channel losses at the source.
• Features receive equalization capabilities to mitigate intersymbol interference in long traces.

Signal Buffers, Repeaters, Splitters Applications

• High-speed backplane interconnects
• Point-to-point serial links requiring signal conditioning
• Data acquisition systems with high bandwidth requirements

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate packaging variations. Ensure the supplier provides valid traceability documentation to guarantee the integrity of the integrated circuits prior to integration into final assemblies.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when dual-channel CML signal routing with active equalization is required. Compare against the DS42MB200 for higher speed needs or DS25MB200 for lower power applications. Evaluate board space constraints due to the compact WQFN package and ensure thermal management strategies align with the specified operating temperature limits.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DSxxMB200 family of high-speed mux buffers from Texas Instruments. It shares functional similarities with the DS40MB200SQ but includes the NOPB suffix indicating lead-free and RoHS-compliant construction. The series is designed for applications demanding reliable signal integrity in dense electronic environments.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS40MB200SQ/NOPB serves as a direct replacement for the discontinued National Semiconductor DS40MB200SQ. Verify pinout compatibility and electrical specifications before substituting other family members like the DS42MB200TSQ/NOPB, which offers higher data rate support.
