Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint constraints. Ensure the manufacturing date code meets your project's shelf-life policies. Cross-reference the datasheet for reflow soldering profiles to prevent component damage during assembly processes.

Oscillators Selection Notes

Select this component when a 43.75 MHz reference clock is required with LVCMOS compatibility. Consider the 3.3V operating voltage range to ensure compatibility with your system's power rails. Evaluate the need for standby functionality if power conservation is a priority. Verify that the small form factor fits within the available board space constraints.
