Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output swing is compatible with the receiving logic inputs. Check the operating temperature range specifications to ensure suitability for your environmental conditions. Validate the physical footprint compatibility with your PCB layout.

Selection Notes

Select this component when a low-voltage, small-form-factor oscillator is required. Consider the LVCMOS output type for direct digital interface compatibility. Evaluate the 1.8V supply constraint against available power resources. Assess the need for an enable pin for power optimization. Compare package dimensions against board space limitations.
