DS91M125TMA

Signal Buffers, Repeaters, Splitters Overview

The DS91M125TMA/NOPB is an LVDS interface integrated circuit manufactured by Texas Instruments, functioning as a 1:4 M-LVDS repeater. It accepts a single LVDS input and provides four M-LVDS outputs. The device supports data rates up to 250 Mb/s with a propagation delay of 8.5 ns. It operates on a 3.3 V supply voltage within a range of 3 V to 3.6 V, drawing 78 mA of operating current. The component is housed in a 16-pin SOIC package and is rated for industrial temperatures from -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Converts low-voltage differential signaling inputs to multi-point LVDS outputs for signal distribution
• Provides one receiver channel to accept source signals and four driver channels for fan-out
• Operates reliably across extended industrial temperature ranges without external clocking

Signal Buffers, Repeaters, Splitters Applications

• High-speed digital signal distribution in industrial automation systems
• Fan-out buffering for display panels requiring multiple synchronized video lines
• Test and measurement equipment needing precise signal replication

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix (e.g., TMA vs TMAX) to confirm the packaging format, as tube and reel variants exist for this series. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the design accommodates the specified 3.3 V power rail and thermal dissipation requirements for the SOIC-16 package during operation.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the DS91M125TMA when a single LVDS source must drive four distinct M-LVDS loads. Compare against the DS91M124 if TTL/CMOS inputs are required instead of LVDS. Consider the DS91D176 for simpler point-to-point conversion needs. Verify that the 250 Mb/s maximum speed meets the system timing requirements.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the DS91M125 family of high-speed interface devices designed for robust signal integrity. It complements other Texas Instruments LVDS products like the DS91M047 quad driver. The device addresses the need for signal regeneration and distribution in noisy environments where standard CMOS levels are insufficient.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The DS91M124TMA/NOPB serves as a functional alternative if LVCMOS or LVTTL inputs are preferred over LVDS inputs, though it exhibits a lower propagation delay of 6.5 ns.
