Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended temperature range (-40°C to +85°C) compared to standard commercial variants. Confirm that the 13pF load capacitance matches the target circuit design requirements. Ensure the 4-SMD footprint aligns with the PCB layout specifications. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is required for digital logic or communication interfaces. The 40 Ohm ESR must be compatible with the oscillator circuit's drive level limitations. Consider the 13pF load capacitance to ensure accurate frequency tuning without external trimming. Evaluate the physical size constraints against available board space for the 6.0x3.5mm package.

Crystals Part Context

This component belongs to the CTS 406 series of surface-mount crystals. The series offers various frequencies and packages tailored for different size and performance requirements. The 406 series generally supports both commercial and industrial temperature ranges depending on the specific ordering code suffixes.

Crystals Replacement Considerations

Direct substitutes include other 24.576 MHz SMD crystals with matching 13pF load capacitance and similar ESR values. Verify that alternative parts support the -40°C to +85°C range if industrial grade performance is mandatory. Cross-reference pinout and footprint dimensions to ensure mechanical compatibility.
