DS90LV049HMT

Overview

The DS90LV049HMT/NOPB is a high-speed LVDS interface integrated circuit manufactured by Texas Instruments. It features two drivers and two receivers, supporting data rates up to 400 Mbps. The device operates on a single 3V to 3.6V power supply with a typical operating voltage of 3.3V. It accepts LVTTL or LVCMOS inputs and provides differential LVDS outputs. Key electrical parameters include a propagation delay of 3.5 ns, a maximum input voltage of 35 mV, and a minimum input voltage of -100 mV. The component supports an extended industrial temperature range from -40°C to +125°C and has a power dissipation rating of 866 mW.

Feature Summary

• Supports full-duplex communication with integrated dual-line drivers and receivers for simultaneous transmission and reception.
• Compatible with standard LVTTL and LVCMOS logic levels at the input stage, simplifying integration with common digital interfaces.
• Designed for high-temperature environments, ensuring reliable operation in demanding industrial applications.

Applications

• Industrial control systems requiring robust signal transmission over long distances.
• Display interfaces connecting source boards to display panels via LVDS links.
• Data acquisition systems utilizing high-speed serial communication protocols.

Procurement Notes

Verify the suffix 'HMT' against 'HMTX' or 'TMT' to confirm package type and temperature grade before ordering. Ensure the specific variant matches the required thermal performance and physical footprint for the target PCB design. Confirm RoHS compliance status through official manufacturer documentation.

Selection Notes

Select this component when dual-channel LVDS transmission is needed with LVTTL/LVCMOS compatibility. Consider the extended temperature range if the application environment exceeds standard commercial limits. Evaluate the TSSOP-16 package constraints regarding board space and thermal management requirements.

Part Context

This part belongs to the DS90LV049 series of low-voltage differential signaling transceivers. It serves as a bridge between parallel logic interfaces and serial LVDS lines, enabling high-speed data transfer while reducing electromagnetic interference compared to parallel buses.

Replacement Considerations

The DS90LV049TMT/NOPB offers similar functionality but typically supports a lower maximum operating temperature of +85°C. Verify thermal requirements carefully when substituting. Other variants in the family may differ in packaging or speed capabilities.
