Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 2.5V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 7.0x5.0mm SMD package dimensions. Check for any specific reflow soldering profile recommendations provided in the manufacturer datasheet to ensure joint integrity during assembly processes.

Selection Notes

Select this component when a 13.4965 MHz clock signal is required with LVCMOS compatibility. Consider the 2.5V operating voltage constraint relative to other available logic families. Evaluate the 4-SMD package size against available board space constraints. Compare the -40°C to 85°C operating range against environmental conditions to ensure reliable performance throughout the intended operational lifecycle without requiring specialized industrial-grade variants.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series offers various frequency options within a standardized 4-SMD package form factor.
