DS90LV017ATM-NS

Overview

The DS90LV017ATM is a single LVDS differential line driver manufactured by National Semiconductor. It accepts CMOS or TTL input signals and converts them into low-voltage differential signaling (LVDS) outputs compliant with the TIA/EIA-644 standard. The device operates on a single 3.0 V to 3.6 V power supply, typically 3.3 V, with a maximum data rate of 600 Mb/s. Key electrical parameters include a propagation delay of 1.5 ns, an operating current of 10 mA, and a power dissipation of 1.19 W. It functions within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Compliant with TIA/EIA-644 LVDS standards for interoperability
• Low output voltage swing reduces electromagnetic interference
• Current-mode drive minimizes short-circuit fault currents
• Pass-through pin configuration simplifies PCB layout

Applications

• High-speed serial data transmission links
• Point-to-point interconnects in industrial systems
• Clock distribution networks requiring low jitter
• Embedded systems with space-constrained PCB layouts

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required thermal and mechanical specifications. Confirm RoHS compliance status through official documentation, as legacy stock may vary. Cross-reference the part number against current Texas Instruments catalogs to identify any updated equivalents or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a single-channel LVDS driver is required for high-speed digital interfaces. It is suitable for applications needing conversion from parallel CMOS/TTL logic to differential signaling. Consider the 600 Mb/s speed limit and 3.3 V supply requirement. Evaluate the SOIC-8 package size against available board real estate. Ensure the load impedance matches standard LVDS requirements for proper signal integrity.

Part Context

This device belongs to the DS90LV01x family of low-voltage differential signaling components originally developed by National Semiconductor. These drivers are designed for high-speed, low-power data transmission. The family includes various channel configurations and receiver counterparts. The transition to Texas Instruments has maintained the functional lineage while updating manufacturing processes and support structures for these interface ICs.

Replacement Considerations

The DS90LV017ATMX/NOPB is a confirmed equivalent from Texas Instruments. Verify pin compatibility and electrical characteristics before substitution. Other family members like the DS90LV018A serve as receivers rather than drivers.
