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 voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained layouts where traditional through-hole or larger SMD oscillators do not fit.
