LMH0074SQE/NOPB

Specialized Overview

The LMH0074SQE/NOPB is an adaptive cable equalizer manufactured by Texas Instruments, designed for SMPTE 259M and 344M serial digital video interfaces. It operates within a supply voltage range of 3.135 V to 3.465 V and supports data rates up to 3 Gb/s. The device is housed in a 16-pin WQFN package with exposed pad, suitable for surface mount installation. It functions across an industrial temperature range from -40°C to +85°C. Key electrical characteristics include a typical operating current of 85 mA and a power dissipation capability relevant to its thermal design constraints.

Specialized Feature Summary

• Adaptive equalization technology automatically adjusts to varying cable lengths and signal degradation conditions without manual configuration.
• Integrated mute functionality allows for controlled output silencing via the MUTEref pin to manage signal transitions.
• Compliance with SMPTE 259M and 344M standards ensures compatibility with standard SD/HD serial digital video signals.

Specialized Applications

• SDI signal distribution systems requiring cable loss compensation
• Professional video equipment input stages for long cable runs
• Broadcast infrastructure utilizing SMPTE 259M/344M compliant links

Specialized Procurement Notes

Verify the specific suffix 'SQE' against the manufacturer's latest datasheet to confirm package variant and tape/reel specifications. Ensure the NOPB designation aligns with lead-free and RoHS compliance requirements for your assembly process. Cross-reference the active status and moisture sensitivity level before finalizing component selection for production.

Specialized Selection Notes

Select this component when designing for SMPTE 259M or 344M serial digital video applications requiring adaptive equalization. Consider the 16-WQFN package dimensions for PCB layout constraints. Evaluate the 3.3V nominal supply requirement and ensure thermal management supports the device's power dissipation profile within the specified operating temperature range.

Specialized Part Context

This part belongs to the LMH0074 series of adaptive cable equalizers from Texas Instruments. It serves as a solution for extending the reach of serial digital video signals over copper cabling. The family includes variants such as LMH0074SQ and LMH0074SQX, differing primarily in packaging and reel configurations while maintaining identical functional performance.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers include LMH0074SQ-NOPB, LMH0074SQ/NOPB, LMH0074SQX-NOPB, and LMH0074SQX/NOPB. These variants share the same core functionality and pinout but may differ in shipping packaging or minor mechanical attributes.
