Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the PCB footprint matches the 2.0x1.6 mm SMD no-lead package specifications. Confirm that the 1.8V supply rail stability meets the oscillator's operational needs to maintain signal integrity.

Oscillators Selection Notes

Select this component when a 30.72 MHz reference is required in a minimal footprint form factor. Consider the 1.8V operating voltage constraint relative to other system rails. Evaluate the need for power-down functionality if energy efficiency during idle states is a priority for the application design.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, designed for high-reliability frequency control applications. The series typically offers various frequency options within the same physical package, allowing for design flexibility while maintaining consistent board layout constraints across different product variants.

Oscillators Replacement Considerations

Direct substitutes must match the 30.72 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6 mm package. Verify pinout compatibility and electrical characteristics before swapping manufacturers.
