Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0mm x 1.6mm 4-SMD No Lead package dimensions to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a precise 34.18 MHz reference is required in space-constrained applications. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. The integrated power-down feature allows for dynamic power management strategies in battery-operated or energy-sensitive designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within the LVCMOS format. The 'PD' suffix indicates the inclusion of a power-down pin or control capability, distinguishing it from standard continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 34.18 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent performance specifications such as frequency stability and phase noise if available in official datasheets.
