DS90LV047ATMX

Overview

The DS90LV047ATMX is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a quad CMOS differential line driver, featuring four independent drivers and four receivers within a single package. The device supports data rates up to 400 Mb/s with a propagation delay of 1.7 ns. It operates on a supply voltage ranging from 3 V to 3.6 V, typically at 3.3 V, with a maximum power dissipation of 1.088 W. The component accepts CMOS or TTL input signals and outputs LVDS signals. It is housed in a 16-pin SOIC-Narrow package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four high-speed differential drivers and receivers for parallel data transmission.
• Compatible with standard CMOS and TTL logic input levels.
• Designed for low electromagnetic interference and reduced power consumption via LVDS technology.

Applications

• High-speed parallel data bus interfaces in industrial equipment.
• Video signal transmission in display systems.
• Data acquisition systems requiring reliable differential signaling.

Procurement Notes

Verify the specific suffix and RoHS compliance status carefully, as the DS90LV047ATMX is listed as obsolete in some distributor records while the NOPB variant remains active. Confirm availability through authorized channels or surplus suppliers, as standard production may have ceased. Ensure the received component matches the exact package type and marking to avoid integration issues in existing designs.

Selection Notes

Select this component when a quad LVDS driver is required for CMOS/TTL to LVDS conversion. Consider the DS90LV047ATMX/NOPB if lead-free manufacturing and RoHS compliance are mandatory for the project. Evaluate the 16-SOIC package constraints against board space requirements. Verify that the 400 Mb/s speed meets the system bandwidth needs without requiring higher-performance alternatives.

Part Context

This part belongs to the DS90LV047A series of LVDS interface devices from Texas Instruments. It is designed to replace older ECL or CML drivers in modern low-voltage digital systems. The series provides a standardized solution for long-distance, high-speed serial and parallel data transmission with minimal signal integrity issues.

Replacement Considerations

The DS90LV047ATMX/NOPB is the direct lead-free and RoHS-compliant equivalent. Check for pin-compatible upgrades within the same family if the obsolete status causes supply chain risks. Ensure any substitute maintains the 4-driver/4-receiver configuration and 400 Mb/s capability.
