Procurement Notes

Verify the specific target frequency during ordering as this component requires programming. Confirm that the 1.8V supply voltage aligns with system requirements. Ensure the 4-SMD package dimensions fit the PCB layout. Check RoHS compliance status if required by project specifications. Validate the standby current consumption against power budget constraints.

Selection Notes

Select this model when a programmable CMOS oscillator with 1.8V operation is needed. Consider the ±100ppm stability for applications not requiring high precision. Evaluate the 1MHz to 166MHz range against signal requirements. Compare package size against available board space. Assess thermal performance within the -20°C to +70°C operational window.
