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 rail is stable and meets the current consumption specifications outlined in the official datasheet. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions to prevent mechanical stress during assembly.

Oscillators Selection Notes

Select this component when a 34.184 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the need for a standby feature. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space. Compare against other frequencies in the series if the exact 34.184 MHz is not critical.
