Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the inclusion of the power-down pin functionality as documented. Ensure the supply voltage requirement matches the 1.8V specification provided in the official datasheet. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 45 MHz clock source with LVCMOS outputs is required. The 1.8V supply voltage makes it suitable for low-voltage digital logic families. The integrated power-down feature allows for system-level power management optimization. Verify that the operating temperature range meets the environmental requirements of the intended application environment.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which offers various frequencies and voltage options. The 18QHTF21 prefix indicates a specific form factor and performance class within the manufacturer's portfolio. Similar parts in this series may differ in frequency, voltage, or package size while maintaining the same core oscillator technology and output logic standards.

Oscillators Replacement Considerations

Direct substitutes must match the 45 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative component supports the power-down function if required. Cross-reference the pinout and electrical characteristics to ensure functional compatibility without circuit modification.
