DS42MB200TSQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS42MB200TSQ/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 4.25 Gbps with CML input and output interfaces. The device integrates two independent 2:1 multiplexers and two 1:2 demultiplexers within a single package. It operates on a supply voltage ranging from 3.135 V to 3.465 V, drawing a typical operating current of 289 mA. The component is housed in a 48-pin WQFN package (7x7 mm) suitable for surface mount technology. It functions reliably across an industrial temperature range of -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix configuration when ordering, as the NOPB designation indicates RoHS compliance and lead-free status. Confirm availability through authorized distributors, noting that production cycles may vary. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when dual-channel CML muxing at 4.25 Gbps is required within a compact footprint. Compare pinout compatibility with legacy designs if replacing older versions. Evaluate power consumption against system thermal constraints given the 289 mA operating current. Ensure the PCB layout supports the 48-WQFN package requirements for optimal thermal dissipation and signal performance.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS42MB200 series of high-speed multiplexers. It shares functional similarities with other members like the DS42MB100 but offers higher channel density. The TSQ variant denotes a specific tape-and-reel packaging option. It serves as a critical interface component in systems bridging different data rate domains or expanding signal paths in high-bandwidth applications.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS42MB200TSQ is listed as obsolete, with the DS42MB200TSQ/NOPB serving as the direct replacement. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Review any changes in packaging or environmental compliance between the original and replacement parts.
