LMH2191TMX/NOPB

Clock Buffers, Drivers Overview

The LMH2191TMX/NOPB is a dual-channel clock tree driver manufactured by Texas Instruments. It functions as a fan-out buffer with a 1:2 input-to-output ratio, supporting maximum frequencies of 52 MHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and is housed in an 8-DSBGA package. It is designed for surface mount installation and supports standard clock inputs without differential signaling requirements. The component is rated for industrial operating temperatures between -40°C and +85°C.

Clock Buffers, Drivers Feature Summary

• Dual-channel architecture providing two independent output buffers
• Maximum operating frequency of 52 MHz
• Single-supply operation compatible with 2.5 V to 5.5 V power rails
• Compact 8-pin DSBGA surface-mount packaging

Clock Buffers, Drivers Applications

• Clock distribution networks requiring signal buffering
• Fan-out buffering for low-frequency timing references
• General-purpose clock tree drivers in embedded systems

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'TMX' indicates tape-and-reel packaging when ordering. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Check current availability status as production cycles may vary. Ensure the design accommodates the 8-DSBGA footprint dimensions and thermal requirements specified in the mechanical outline drawing.

Clock Buffers, Drivers Selection Notes

Select this component when a dual-output buffer is required for clock signals up to 52 MHz. It is suitable for applications needing a 1:2 fan-out ratio with single-ended I/O. Consider the 8-DSBGA package size constraints during PCB layout. Verify that the system power supply falls within the 2.5 V to 5.5 V range to ensure proper operation across the full temperature spectrum.

Clock Buffers, Drivers Part Context

This part belongs to the LMH2191 series of clock drivers. It is distinct from RF detectors like the LMH2110 or amplifiers like the LMH6503. The device serves specifically as a timing signal conditioner rather than a signal detector or variable gain amplifier. It complements other clock components in systems requiring precise frequency distribution.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives only if they match the 52 MHz frequency limit and 8-DSBGA package specifications.
