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 enable/disable pin configuration matches the control logic available in the host application to guarantee proper operation during standby or active states.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The 4-SMD no-lead package offers a small footprint suitable for high-density PCB layouts. Consider the enable/disable feature if power management during inactive periods is a critical design requirement for the specific application.
