DS15BR401TSQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS15BR401TSQ/NOPB is a quad-channel LVDS buffer and repeater manufactured by Texas Instruments. It supports data rates up to 2 Gb/s with low jitter performance from DC to the maximum speed. The device accepts CML, LVDS, or LVPECL input signals and converts them to LVDS outputs. It operates on a single 3.3 V power supply with a minimum voltage of 3 V and a maximum of 3.6 V. The component features a propagation delay of 2 ns and draws 215 mA of operating current. It is housed in a WQFN-32 package suitable for surface mount applications.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides four independent channels for buffering and repeating LVDS signals.
• Accepts multiple input standards including CML, LVDS, and LVPECL.
• Operates with low jitter characteristics across the full data rate range.
• Designed for high noise immunity in signal transmission paths.

Signal Buffers, Repeaters, Splitters Applications

• High-speed serial communication interfaces
• Data acquisition systems requiring signal distribution
• Test and measurement equipment

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the manufacturer designation as Texas Instruments despite the query specifying National Semiconductor, as TI acquired the relevant interface product lines. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the TSQ variant matches the required automotive-grade temperature range and WQFN-32 packaging specifications for the target design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when interfacing between different logic families such as converting CML or LVPECL sources to LVDS loads. The quad-channel architecture reduces board space compared to discrete solutions. Verify that the 3.3 V supply rail aligns with the system power budget and that the WQFN-32 footprint fits the PCB layout constraints.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the DS15BR401 series of LVDS interface ICs. It shares functional similarities with the DS15BR400 but offers enhanced performance capabilities. The TSQ suffix distinguishes it from commercial grade parts, indicating qualification for broader environmental conditions within the specified operating temperature range.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS15BR400 serves as a related alternative within the same family. Cross-reference pinouts and electrical parameters carefully before substitution to ensure compatibility with existing LVDS trace impedance and termination requirements.
