DS92LV040ATLQAX/NOPB

Overview

The DS92LV040ATLQAX/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments, originally developed under the National Semiconductor brand. This quad-channel bus transceiver features four drivers and four receivers, supporting data rates up to 155 Mb/s. It accepts LVTTL or LVDS inputs and provides BLVDS outputs. The device operates on a single 3.3 V power supply within a voltage range of 3.0 V to 3.6 V. It is housed in a 44-pin WQFN package with dimensions of 7 x 7 mm and a height of 0.8 mm. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports simultaneous transmission of clock and data signals over a common bus architecture
• Enables connection of multiple drivers and receivers via a single general-purpose bus
• Provides independent channel enable control for flexible system configuration

Applications

• Advanced Telecommunications Computing Architecture (ATCA) backplanes
• Micro Telecommunications Computing Architecture (MicroTCA) systems
• Wireless base station infrastructure
• Communication system routers
• LXI test instrumentation

Procurement Notes

Verify the manufacturer designation carefully, as the part number indicates Texas Instruments despite the original National Semiconductor design history. Confirm the specific suffix 'AX' against current datasheets to ensure pinout and electrical characteristics match the intended application requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring multi-drop LVDS connectivity for both clock and data distribution. Ensure the design supports the specified 155 Mb/s data rate and 3.3 V operating voltage. Verify that the 44-pin WQFN package fits the available PCB real estate and thermal management constraints for the target environment.

Part Context

This device belongs to the DS92LV040 family of LVDS transceivers. It was introduced as a solution for advanced computing architectures like ATCA and MicroTCA. The component integrates high-speed differential signaling capabilities into a compact form factor, facilitating robust signal integrity in noisy industrial and telecommunications environments.

Replacement Considerations

Check for direct equivalents within the DS92LV040 series. Verify compatibility with other National Semiconductor or Texas Instruments LVDS transceivers if pin-to-pin substitution is required. Ensure any replacement maintains the same channel count and data rate specifications.
