Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for any specific handling or storage instructions related to the lead-free package.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the physical dimensions of the 4-SMD package to ensure compatibility with automated assembly processes and available board space.

Oscillators Part Context
