Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable to maintain oscillator performance. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues.

Oscillators Selection Notes

Select this model when a low-voltage, small-footprint oscillator is required for timing applications. Consider the operating temperature range and stability specifications relative to your environmental conditions. Compare alternative frequencies within the same series if the exact 38.016 MHz rate is not strictly necessary for your system clock.
