Oscillators Procurement Notes

Verify the exact frequency specification against the official datasheet, as similar part numbers in this series may vary slightly in frequency values such as 25.009 MHz or 25.768 MHz. Confirm that the 1.8V supply voltage requirement aligns with your system design. Ensure the 4-SMD no lead package footprint matches your PCB layout constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 25.0025 MHz clock source is required for LVCMOS-compatible digital circuits. The choice depends on the need for low voltage operation at 1.8V and the availability of an enable/disable pin for power management. Consider the small form factor of the 4-SMD package if space constraints are critical in the application design.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which includes various frequencies like 25.020 MHz and 19.0625 MHz.
