Oscillators Procurement Notes

Verify the specific frequency tolerance 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 no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS interface compatibility. The inclusion of a standby feature makes it suitable for applications requiring power efficiency. Consider the 4-SMD form factor for space-constrained designs where surface mounting is preferred over through-hole technology.
