Crystals Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's current product status, as availability may vary by region or distributor. Confirm that the 8pF load capacitance matches the target circuit design requirements. Ensure the 4-SMD footprint aligns with the PCB layout specifications. Check for any obsolescence notices from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency with ±10ppm stability is required. The 8pF load capacitance must match the oscillator circuit's external capacitors. Consider the 120 Ohm ESR value for oscillator startup reliability. The 4-SMD package size is appropriate for space-constrained designs requiring surface-mount technology.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages. The 402F19211CKR specifically denotes the 19.2 MHz variant with 8pF load capacitance in a standard SMD package. It is distinct from variants with different load capacitances or tolerances within the same frequency family.

Crystals Replacement Considerations

Equivalent parts include 402F19211CAR and 402F19211CDT from CTS-Frequency Controls, though load capacitance differs. Cross-manufacturer substitutes require verification of frequency, load capacitance, and ESR parameters.
