Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the inclusion of the power-down feature as documented. Ensure the operating environment aligns with the component's specified temperature range and voltage requirements. Confirm that the 4-SMD no-lead package footprint matches the target PCB layout design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 118.70248 MHz clock source is required within space-constrained designs. The 1.8V supply requirement makes it suitable for modern low-power digital logic families. Consider the LVCMOS interface compatibility with the receiving circuitry to ensure proper signal integrity and voltage level matching during system integration.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and package options. The '-PD' suffix specifically denotes the power-down capability, distinguishing it from standard continuous-operation variants within the same physical form factor and electrical family.

Oscillators Replacement Considerations

Direct substitutes must match the 118.70248 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical specifications to ensure functional equivalence without redesigning the host circuit board.
