Crystals Procurement Notes

Verify the specific suffix designation against official CTS documentation, as generic model numbers may obscure critical variations in tolerance or packaging. Confirm current availability status directly with authorized distributors, as supply chain fluctuations frequently impact stock levels for standard frequency components. Ensure compatibility with existing PCB footprint and reflow soldering profiles prior to procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz reference signal is required within a constrained surface-mount area. The 8 pF load capacitance must match the oscillator circuit design to ensure accurate frequency generation. Evaluate the ±15 ppm tolerance against system phase noise requirements and confirm that the -20°C to +70°C operating range aligns with the intended environmental conditions.
