• Communication interface timing references

Crystals Procurement Notes

Verify the specific suffix 'KR' against official CTS documentation to confirm tape and reel packaging requirements. Ensure the target circuit design accommodates the 8pF load capacitance and 120 Ohms ESR specifications. Confirm that the 4-SMD footprint matches the PCB layout dimensions of 2.00mm by 1.60mm. Validate thermal performance within the specified -40°C to +85°C operational range before final integration.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency with tight ±10ppm tolerance is required. The 8pF load capacitance suits circuits designed for lower capacitive loading compared to standard 12pF variants. The compact SMD package facilitates high-density board layouts. Consider the 120 Ohms ESR value for oscillator circuit stability analysis. Ensure the application environment remains within the industrial temperature limits.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and package sizes for general-purpose timing applications. The 402F1921XIKR specifically addresses needs for 19.2 MHz signals in space-constrained designs. It shares common manufacturing processes with other 402 series components but differs in electrical parameters like load capacitance and tolerance.

Crystals Replacement Considerations

Direct substitutes include 402F1921XILR and 402F1921XILT from CTS-Frequency Controls. Verify if alternative packages or tolerances are acceptable for the specific application requirements.
