DS92LV040ATLQA/NOPB

Overview

The DS92LV040ATLQA/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a four-channel bus LVDS transceiver, integrating four drivers and four receivers within a single package. The device supports data transmission rates up to 155 Mbps, making it suitable for high-speed digital video and data applications. It accepts LVTTL inputs and provides BLVDS outputs, facilitating signal conversion between logic-level interfaces and differential signaling standards. The component operates on a supply voltage ranging from 3.0 V to 3.6 V, with a typical operating voltage of 3.3 V. It is housed in a 44-pin WQFN package measuring 7 mm by 7 mm with a height of 0.8 mm, designed for surface-mount technology.

Feature Summary

• Integrates four independent drivers and four receivers for bidirectional or parallel data transmission
• Converts LVTTL input signals to BLVDS output format for noise-immune communication
• Supports data rates up to 155 Mbps for high-speed digital interface requirements
• Operates within a standard 3.3 V power supply range with defined voltage limits

Applications

• High-speed digital video signal transmission systems
• Industrial control networks requiring noise-resistant differential signaling
• Data acquisition systems utilizing LVDS interconnects
• Embedded systems connecting logic-level components to differential buses

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest documentation to confirm pinout compatibility and revision status. Ensure the ordering quantity aligns with the specified factory packaging multiples, typically 2500 units per reel for this part number. Confirm RoHS compliance details directly with the supplier, as regulatory statuses can vary by production batch and region. Cross-reference the datasheet version date to ensure all electrical characteristics match the design requirements.

Selection Notes

Select this component when a compact solution for four-channel LVDS transmission is required alongside LVTTL interfacing. The 44-pin WQFN package offers a small footprint suitable for space-constrained designs. Verify that the target application operates within the -40°C to +85°C temperature range and utilizes a 3.3 V power domain. Consider the 155 Mbps speed limit to ensure it meets the bandwidth needs of the specific data lines being routed.

Part Context

This device belongs to the DS92LV040 series of LVDS interface ICs from Texas Instruments. It is part of a broader family of differential signaling solutions designed for robust data transmission in noisy environments. The 'NOPB' suffix indicates lead-free construction and absence of certain halogenated compounds, adhering to environmental standards. It serves as a bridge between TTL-compatible logic circuits and LVDS-based backplanes or cables.

Replacement Considerations

The DS92LV040ATLQAX/NOPB is listed as a variant with identical functional specifications but potentially different packaging or tape-and-reel configurations. Verify mechanical dimensions and thermal pad requirements before substitution. No other direct cross-manufacturer equivalents are confirmed in the provided source material.
