Procurement Notes
Verify the specific supply voltage and load capacitance requirements against the official datasheet before integration. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure compatibility with the system's operating temperature range as specified by the manufacturer.
Selection Notes
Select this component when a 100.050 MHz LVCMOS clock source is required in a small form factor. Consider the enable/disable feature if power management during idle states is necessary. Verify that the manufacturing origin from Mercury Electronic Ind. Co., Ltd meets quality standards for the intended application environment.
Part Context
This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronic. The series includes various frequencies such as 37.888 MHz and 86.996875 MHz, all sharing similar package constraints and LVCMOS output characteristics. The manufacturer specializes in frequency control products including TCXOs and VCXOs.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants like 18QHTF21-86.996875-OE or 18QHTF21-37.888-OE if frequency adjustment is acceptable. Cross-reference with Mercury United Electronics equivalents for potential sourcing alternatives.
