• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific suffix 'CKR' against official CTS documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard reflow soldering profiles for lead-free RoHS compliant components. Cross-reference the 8pF load capacitance requirement with the target circuit design to maintain frequency accuracy within the specified ±30 ppm tolerance limits.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with low cost and small size is required. The 8pF load capacitance must match the oscillator circuit's external capacitors. Consider the ±30 ppm stability for applications not requiring high-precision timing. The 4-SMD package offers reliable mounting for high-volume production environments.

Crystals Part Context

This part belongs to the 402 Series of SMD crystals from CTS-Frequency Controls. The series provides various frequencies and load capacitances in a standardized 2.00mm x 1.60mm footprint. These components are designed for general-purpose timing applications where moderate stability and compact form factors are prioritized over ultra-high precision.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with 8pF load capacitance and similar dimensions. Verify that alternative parts support the same 100 Ohm ESR and operate within the -20°C to +70°C temperature range to ensure functional equivalence.
