Oscillators 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 4-SMD footprint matches the PCB layout silkscreen and pad dimensions. Check the datasheet for any specific handling or storage conditions required for the quartz component.

Oscillators Selection Notes

Select this oscillator when a precise 26.45125 MHz reference is required with low profile packaging. Consider the LVCMOS output compatibility with the receiving logic family. Evaluate the enable pin utility if dynamic power saving is necessary. Compare the 2.5V operation against available system voltages to ensure proper level shifting or direct drive capability without additional components.

Oscillators Part Context

This part belongs to the H_QF series of differential and single-ended oscillators from Mercury Electronics. The series is characterized by small form factors suitable for portable electronics. The 18QHTF21 designation indicates a specific size and pin configuration within the manufacturer's SMD oscillator lineup, distinct from their larger through-hole or wider SMD variants.

Oscillators Replacement Considerations

Direct replacements must match the 26.45125 MHz frequency, 2.5V supply, and 4-SMD 2.5x2.0mm package. Verify output logic compatibility (LVCMOS) and enable pin functionality. Cross-reference pinouts to ensure electrical connectivity matches the original design.
