• Frequency reference for automotive microcontrollers

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the AEC-Q200 certification status remains valid for the intended automotive application environment before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 27.6 MHz frequency reference is required for automotive-grade circuits. The choice is appropriate for designs necessitating AEC-Q200 compliance and operation within a -40°C to +85°C temperature range. Ensure the circuit layout supports the 2.5 mm x 2.0 mm footprint and accounts for the 100 Ohm ESR value during oscillator design.

Crystals Part Context

This part belongs to the TXC automotive crystal family, characterized by seam-seal ceramic packages and strict quality certifications. It serves as a passive frequency control element, distinct from active oscillators, requiring an external oscillator circuit to generate a clock signal. The model represents a standard solution for high-reliability timing applications in the automotive sector.

Crystals Replacement Considerations

Cross-reference with other TXC models sharing the same 27.6 MHz frequency, 10 pF load capacitance, and AEC-Q200 qualification. Verify that alternative candidates match the 2.5 mm x 2.0 mm package dimensions and -40°C to +85°C operating temperature range to ensure mechanical and thermal compatibility.
