Overview
The LMH7220MKX is a high-speed comparator manufactured by Texas Instruments, featuring Low-Voltage Differential Signaling (LVDS) outputs. It operates within a supply voltage range of 3.0 V to 5.5 V and supports input frequencies up to 1.4 GHz with an output frequency range extending to 22.6 GHz. The device functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a compact VQFN-48 form factor suitable for surface-mount technology, it draws approximately 500 mA of operating current at a nominal 3.3 V supply.
Feature Summary
- Integrates LVDS output drivers for high-speed digital signaling compatibility
- Supports wideband RF synthesis applications through broad frequency operation
- Designed for robust performance in industrial and commercial temperature environments
Applications
- RF synthesizer local oscillator generation
- High-speed data acquisition systems
- Wireless communication infrastructure
Procurement Notes
Verify the specific suffix 'MKX' against official Texas Instruments documentation to confirm package type and reel specifications. Ensure the component matches the required VQFN-48 footprint and lead finish. Cross-reference the datasheet revision date to validate electrical characteristics against your design requirements before finalizing procurement orders.
Selection Notes
Select this component when LVDS interface compatibility is required for high-frequency signal processing. Evaluate the 500 mA current consumption against system power budgets. Confirm that the VQFN-48 package dimensions fit the available PCB real estate and thermal management constraints for the intended application environment.
Part Context
This part belongs to the high-speed comparator family within Texas Instruments' portfolio, often utilized in RF and microwave subsystems. It shares functional similarities with other high-speed comparators but is distinct due to its integrated LVDS output stage and specific frequency response capabilities designed for modern wireless standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official replacement guide or contact technical support for validated alternatives.
