Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure exact electrical parameters match the design requirements. Confirm that the package dimensions and pin configuration align with the intended PCB footprint. Check for any recent product change notifications regarding material composition or manufacturing location updates.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with strict tolerance limits. Ensure the circuit design supports the 20 pF load capacitance to maintain accuracy. Verify that the 80 Ohm ESR value is compatible with the oscillator circuit's drive level specifications to prevent over-driving the crystal.

Crystals Part Context
