Crystals Procurement Notes

Verify the specific suffix requirements against the official CTS datasheet to ensure correct packaging and lead time alignment. Confirm that the HC-49/US surface-mount variant matches the target PCB footprint and thermal profile. Cross-reference the 28.63636 MHz frequency requirement with system clock specifications to avoid timing mismatches during procurement planning.

Crystals Selection Notes

Select this component when a surface-mount crystal with a 20pF load capacitance is required for 28.63636 MHz applications. Consider the 30 Ohm ESR value for oscillator circuit compatibility. Ensure the -20°C to 70°C operating range meets the environmental conditions of the final assembly. Verify that the fundamental mode operation aligns with the host oscillator design constraints.

Crystals Part Context

This part belongs to the ATS(-SM) Series from CTS-Frequency Controls, which specializes in surface-mount crystals. The ATS286ASM-1 shares the HC-49/US form factor with other series members but differs in frequency and electrical parameters. It serves as a surface-mount alternative to through-hole variants within the broader ATS product family.

Crystals Replacement Considerations

ATS286ASM-1E is listed as a direct replacement option within the same manufacturer line. Verify if the 'E' suffix denotes a specific environmental or packaging variation before substitution. No third-party substitutes are explicitly confirmed in the provided documentation.
