Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6 mm footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a small form factor and low power consumption are critical. The 1.8V operating voltage makes it suitable for battery-powered devices. The integrated power-down feature allows for extended battery life in standby modes. Consider the LVCMOS compatibility with your target digital logic family to ensure signal integrity without additional level shifting.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages. The 'PD' suffix indicates the inclusion of a power-down pin or function. The 2.0x1.6 mm package size distinguishes it from larger variants in the same product line, targeting high-density board designs.

Oscillators Replacement Considerations

Direct replacements must match the 24.0 MHz frequency, 1.8V supply, and 2.0x1.6 mm package. Verify electrical compatibility including output drive strength and rise/fall times. Cross-reference pinouts to ensure the power-down functionality maps correctly to the new component's configuration.
