Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to guarantee proper solder joint formation and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 24.476 MHz reference is required for LVCMOS compatible circuits. Consider the 1.8V operating voltage constraint to ensure compatibility with existing power rails. Evaluate the need for power down functionality if energy efficiency is critical. Verify that the small form factor fits within the spatial constraints of the target application board layout.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which offers various frequencies within the same physical package. The series provides standardized XO solutions for mass production environments. Other variants in this family share identical electrical characteristics and packaging but differ in output frequency, allowing for streamlined inventory management across different product lines.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series oscillators with identical pinouts and electrical specs, such as the 18QHTF21-51.200-PD or 18QHTF21-96.768-PD, provided the frequency difference is acceptable for the application. Cross-brand replacements require careful verification of pin compatibility, voltage levels, and output logic types.
