DS92LV040ATLQAX

Overview

The DS92LV040ATLQAX is a low-voltage differential signaling (LVDS) bus transceiver manufactured by Texas Instruments. It integrates four drivers and four receivers within a single package, supporting data rates up to 155 Mb/s. The device accepts LVDS or LVTTL inputs and provides corresponding LVDS or LVTTL outputs. It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. The component features a propagation delay of 2.3 ns and dissipates up to 4.8 W of power. It is housed in a 44-pin WQFN package suitable for surface mount technology and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent LVDS drivers and four receivers for high-density signal transmission.
• Supports flexible input/output configurations by accepting both LVDS and LVTTL signals.
• Designed for reliable operation in industrial environments with extended temperature coverage.

Applications

• High-speed digital video interfaces requiring LVDS compliance.
• Industrial control systems utilizing serial communication buses.
• Data acquisition modules needing isolated signal transmission.

Procurement Notes

Verify the specific suffix 'X' against official manufacturer documentation to confirm reel packaging specifications. Ensure compatibility with standard 3.3 V logic levels before integration. Confirm moisture sensitivity handling requirements during storage and assembly processes to maintain device integrity.

Selection Notes

Select this component when four-channel LVDS transmission is required alongside LVTTL interface compatibility. Consider the 44-pin WQFN footprint for PCB layout constraints. Evaluate the 155 Mb/s speed limit against system bandwidth requirements to ensure adequate performance margins.

Part Context

This part belongs to the DS92LV040A series of LVDS interface integrated circuits. It serves as a bridge between parallel LVTTL data sources and serial LVDS transmission lines. The device is designed to reduce electromagnetic interference while maintaining signal integrity over long cable runs in noisy environments.

Replacement Considerations

Consult official substitution guides for equivalent parts within the same family. Verify pinout compatibility and electrical characteristics before replacing existing components in established designs.
