DS40MB200SQ

Overview

The DS40MB200SQ is a dual-channel multiplexer and buffer designed for high-speed serial data transmission. It operates at data rates up to 4.0 Gbps using Current Mode Logic (CML) interfaces. The device integrates transmit pre-emphasis and receive equalization to enhance signal integrity over lossy channels. It supports 2:1 and 1:2 switching configurations, making it suitable for extending the reach of PCI Express and other high-speed interconnects in server and storage applications.

Feature Summary

Integrated signal conditioning with transmit pre-emphasis and receive equalization
Dual-channel architecture supporting 2:1 and 1:2 CML multiplexing
Designed to extend line coverage for high-speed switches and routers

Applications

Server backplane redundancy
Storage Area Network (SAN) infrastructure
PCI Express link extension

Part Context

This component originates from National Semiconductor, which was acquired by Texas Instruments. The part belongs to the DS40MB200 family of high-speed interface chips. While originally branded under National Semiconductor, subsequent documentation and equivalents are managed under the Texas Instruments portfolio following the corporate merger.

Replacement Considerations

The direct equivalent manufactured by Texas Instruments is the DS40MB200SQ/NOPB. This variant maintains identical functional specifications and pinout compatibility while adhering to RoHS standards.
