Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 20.2752 MHz timing. The LVCMOS output ensures direct interfacing with standard logic families without additional level shifting. The enable function allows for dynamic power savings in battery-operated or energy-efficient designs compared to always-on oscillators.

Oscillators Part Context

This model belongs to the 18QHTF21 series of high-frequency crystal oscillators from Mercury Electronics. The series is characterized by small form factors and low voltage operation, targeting portable electronics and compact industrial devices. Mercury Electronics leverages its long-standing expertise in quartz crystal manufacturing to provide stable frequency control solutions.

Oscillators Replacement Considerations

Cross-reference part numbers such as 18QHTF21-20.2752-PD for potential alternative packaging or variant options within the same manufacturer's lineup. Verify that any substitute maintains the identical 20.2752 MHz frequency, 1.8V supply, and LVCMOS output characteristics to ensure functional compatibility.
