Crystals Procurement Notes

Verify the specific suffix EA48 against the manufacturer datasheet to confirm the exact stability grade and packaging configuration. Ensure the selected variant matches the required load capacitance and ESR for the target circuit design. Cross-reference the RoHS compliance status if environmental regulations apply to the final product assembly process.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required for digital logic or communication protocols. The 19 pF load capacitance must match the oscillator circuit requirements. Consider the 120 Ohm ESR for drive level limitations. The SMD2520-4P package size should be evaluated against available PCB real estate and thermal constraints during layout.
