Crystals Procurement Notes

Verify the specific load capacitance requirement of 20 pF against the target oscillator circuit design to ensure accurate frequency operation. Confirm that the operational environment remains within the documented 0°C to +85°C range to maintain the specified ±10 ppm stability. Ensure the PCB layout accommodates the 3.2 mm x 2.5 mm footprint dimensions correctly.

Crystals Selection Notes

Select this component when a 25 MHz reference is required with tight initial tolerance and stability constraints. The 20 pF load capacitance specification must match the host circuit's capacitive requirements. Consider the 50 Ohm ESR value for impedance matching in the oscillator design. This part is suitable for applications demanding reliable performance in moderate temperature variations.

Crystals Part Context

This model belongs to the 7M series of surface-mount crystals manufactured by TXC Corporation. These components are engineered for general-purpose timing applications requiring small form factors. The series supports various frequencies and load capacitances, providing standardized solutions for modern electronic designs needing reliable quartz-based frequency control.

Crystals Replacement Considerations

Cross-reference other 25 MHz crystals with 20 pF load capacitance and identical 3.2x2.5mm SMD footprints. Verify that alternative parts meet the same ±10 ppm tolerance and 0°C to +85°C temperature specifications.
