Crystals Procurement Notes

Verify the specific suffix 'CLR' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the selected variant matches the required load capacitance and ESR limits for the target oscillator circuit design. Cross-reference the RoHS status and moisture sensitivity level during procurement planning.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental resonance is required with tight ±10 ppm stability. The 12 pF load capacitance must align with the host oscillator circuit's external capacitor values. Consider the 60 Ohm ESR limit to ensure adequate drive level margins. Verify that the 4-SMD footprint fits within the available PCB area constraints.
