Crystals Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with target circuit load capacitance requirements. Confirm that the 10pF load capacitance matches the oscillator design specifications. Check current availability status as supply levels may fluctuate. Ensure the selected variant meets the required temperature range and stability specifications for the intended application environment.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with ±10ppm tolerance. Ensure the system oscillator circuit supports a 10pF load capacitance to maintain accuracy. Consider the 120 Ohm ESR value for drive level sensitivity. Verify that the 4-SMD footprint fits within the available PCB area constraints. Compare stability requirements against alternative frequencies if higher precision is needed.
