Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise timing signals. The LVCMOS output ensures compatibility with standard digital logic families. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify that the enable/disable feature meets system power management needs without requiring additional external control circuitry.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific output or packaging variant within the manufacturer's lineup. This model provides a stable clock source for digital circuits requiring low power consumption and small form factors.

Oscillators Replacement Considerations

Direct substitutes include other 18.1MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation.
