DS91M124TMA/NOPB

Overview

The DS91M124TMA/NOPB is an LVDS interface integrated circuit manufactured by Texas Instruments, functioning as a 1:4 M-LVDS repeater. It accepts a single LVCMOS or LVTTL input signal and drives four M-LVDS outputs simultaneously. The device supports data rates up to 250 Mb/s with a propagation delay of 6.5 ns. It operates on a 3.3 V supply voltage within a range of 3 V to 3.6 V, drawing 75 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.

Feature Summary

• Converts single-ended logic signals into differential M-LVDS transmissions for robust long-distance communication
• Provides one-to-four fan-out capability to distribute a single source signal to multiple destinations
• Ensures signal integrity through low-voltage differential signaling with defined common-mode rejection

Applications

• Clock distribution networks requiring high fan-out and jitter attenuation
• High-speed digital video interfaces utilizing M-LVDS standards
• Industrial control systems needing reliable serial data transmission over extended cable lengths

Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required packaging options. Confirm that the RoHS compliance status matches environmental regulations applicable to the target assembly process. Cross-reference the active manufacturing status to avoid obsolescence risks during production planning.

Selection Notes

Select this component when a single-ended logic input must be converted to a differential M-LVDS output with four-way distribution. Ensure the system requires a data rate of 250 Mb/s or lower. Verify that the PCB layout accommodates the SOIC-16 package dimensions and that the power supply provides stable 3.3 V operation within the specified current limits.

Part Context

This device belongs to the DS91M124 series of M-LVDS repeaters designed for high-speed serial data transmission. It complements other interface solutions by bridging standard logic levels with differential signaling requirements. The series focuses on maintaining signal quality across noisy environments while providing necessary fan-out capabilities for complex system architectures.

Replacement Considerations

The DS91M125TMA/NOPB serves as a functional alternative but accepts LVDS inputs rather than LVCMOS/LVTTL. Verify input signal compatibility before substitution. Other family members may offer different pin counts or driver configurations.
