Oscillators Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and load capacitance specifications. Confirm that the package variant aligns with the PCB footprint requirements. Ensure the component meets RoHS and lead-free processing standards for environmental compliance. Cross-reference the datasheet revision to confirm electrical characteristics against the intended application environment.

Oscillators Selection Notes

Select this component when precise frequency stability within ±1.5 ppm is required over wide temperature variations. The HCMOS output interface simplifies integration with standard digital circuits without additional buffering. Consider the low supply current consumption for power-sensitive designs. Verify that the 4-SMD package dimensions fit within the available board space constraints.
