Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications to ensure consistent performance. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent mounting issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs. Consider the physical size constraints of the 4-SMD package when evaluating board space availability for high-density layouts.

Oscillators Part Context

This part belongs to the Mercury Electronics series of quartz-based oscillators. The manufacturer specializes in frequency control products including crystals and filters.
