Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the operating temperature range meets the environmental conditions of the intended deployment. Check for any specific ordering suffixes that may indicate different packaging or testing standards.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 20.48 MHz applications. Consider the ±50 ppm stability as sufficient for general timing needs but not for high-precision synchronization. Evaluate the 24mA current draw against battery life constraints if used in portable devices. Compare package dimensions against available PCB real estate.
