Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before ordering. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Request the official datasheet from the manufacturer to validate electrical characteristics for critical timing applications.

Oscillators Selection Notes

Select this component when a precise 33.33333 MHz clock source is required with low voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. The enable pin allows for power management strategies in battery-operated devices. Consider the thermal performance and stability requirements of the operating environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of MEMS or quartz oscillators from Mercury Electronics. The suffix OE typically denotes a specific packaging or tape-and-reel configuration. Similar models in the series offer different frequencies such as 3.33333 MHz or 50.0333 MHz while maintaining the same package and electrical interface standards.

Oscillators Replacement Considerations

Direct substitutes must match the 33.33333 MHz frequency, LVCMOS output, and 4-SMD package. Verify pinout compatibility and supply voltage range. Check if alternative manufacturers offer equivalent MEMS or quartz oscillators with identical enable functionality.
