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's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions. Check for RoHS compliance status if environmental regulations apply to the final product assembly process.

Oscillators Selection Notes

Select this oscillator when a 22.075 MHz frequency is strictly required alongside LVCMOS outputs. Consider the 1.8V operating voltage and standby feature for battery-powered applications. Evaluate the 4-SMD package size against available board space. Compare performance metrics such as phase noise and stability against alternative models if higher precision is needed for the specific application environment.
