DS25BR120TSD/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS25BR120TSD/NOPB is a single-channel, low-jitter LVDS buffer optimized for high-speed signal transmission over lossy FR-4 printed circuit board backplanes and balanced metal cables. It operates at data rates up to 3.125 Gbps with a supply voltage range of 3V to 3.6V. The device features integrated 100Ω input and output termination to minimize insertion and return losses while reducing component count. It supports LVDS, CML, and LVPECL input levels and functions within an operating temperature range of -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrated transmit pre-emphasis with four selectable levels to compensate for channel loss in backplanes and cables.
• On-chip 100Ω differential input and output termination reduces signal reflection and simplifies board layout.
• High electrostatic discharge (ESD) protection on LVDS I/O pins ensures robustness against static damage.

Signal Buffers, Repeaters, Splitters Applications

• High-speed signal transmission over lossy FR-4 PCB backplanes
• Signal buffering for balanced metal cable interconnects
• Data communication systems requiring low jitter and high noise immunity

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for moisture sensitivity labeling if storage conditions are critical. Confirm that the part number matches the exact functional specification required for the design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single-channel LVDS buffer with integrated termination is required for 3.125 Gbps applications. Consider the WSON-8-EP package for space-constrained designs. Evaluate thermal performance based on the maximum power dissipation and ambient operating conditions. Compare against other series members if multiple channels or different signaling standards are needed.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to the Texas Instruments DS25BR family of high-speed interface buffers. It shares architectural similarities with models like the DS25BR100 and DS25BR110 but offers specific integration features such as built-in termination. The family targets demanding high-speed serial link applications where signal integrity is paramount.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS25BR100TSD/NOPB is a similar single-channel LVDS buffer within the same family. Verify compatibility regarding pinout, electrical characteristics, and packaging before substitution. Ensure that any alternative meets the specific 3.125 Gbps rate and termination requirements of the original design.
