Crystals Procurement Notes

Verify the specific load capacitance requirement of the target oscillator circuit matches the 4 pF specification. Confirm that the 50 Ohm ESR aligns with the driver circuit's drive level constraints. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the package dimensions against the PCB footprint library to guarantee mechanical compatibility during placement.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency is required for digital logic or microcontroller clocks. The 4 pF load capacitance simplifies external capacitor selection in Pierce oscillator configurations. Consider the 4-SMD package for high-density board layouts where space is limited. Evaluate the 50 Ohm ESR against the available drive strength of the host oscillator IC to prevent over-driving the crystal.
