DS90LV047ATM

Overview

The DS90LV047ATM is a 3-V LVDS Quad CMOS Differential Line Driver manufactured by National Semiconductor, now part of Texas Instruments. It integrates four independent differential drivers designed for high-speed data transmission. The device supports data rates up to 400 Mb/s with a typical propagation delay of 1.7 ns. It operates on a single 3.3 V power supply, with a voltage range of 3.0 V to 3.6 V. The component is available in a 16-SOIC package and functions within an operating temperature range of -40°C to +85°C. It accepts CMOS or TTL input signals and outputs compliant LVDS differential signals.

Feature Summary

• Integrates four independent low-voltage differential signaling (LVDS) drivers into a single package.
• Accepts standard CMOS or TTL logic inputs for direct interfacing with digital sources.
• Outputs differential signals compliant with TIA/EIA-644 LVDS specifications.
• Designed for simplified printed circuit board layout through flow-through pin configuration.

Applications

• High-speed serial data transmission in multi-drop bus architectures.
• Clock distribution networks requiring low jitter and skew.
• Interfacing between field programmable gate arrays (FPGAs) and peripheral devices.
• Digital display interfaces and video signal transmission systems.

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required packaging and environmental compliance standards. Confirm availability status, as older revisions may be discontinued or replaced by newer NOPB variants. Cross-reference datasheet revisions to ensure compatibility with current design requirements.

Selection Notes

Select this component when four independent LVDS channels are required from a single source. It is suitable for designs needing direct CMOS/TTL interface without additional level shifting. Consider the 16-SOIC package constraints for PCB space. Verify that the 400 Mb/s data rate meets the system bandwidth requirements. Check thermal dissipation limits if operating at maximum ambient temperatures.

Part Context

This component belongs to the DS90LV047A series of LVDS interface integrated circuits. It serves as a line driver counterpart to receivers like the DS90LV048. The product lineage transitions from National Semiconductor to Texas Instruments, maintaining functional compatibility across generations. It is categorized under LVDS Interface ICs within the broader family of high-speed communication components.

Replacement Considerations

The DS90LV047ATM/NOPB is a lead-free version of the same functional device. Other quad LVDS drivers such as the ADN4667 from Analog Devices offer similar functionality but may require different pinout or voltage considerations. Always verify electrical parameters and pin assignments before substitution.
