Crystals Procurement Notes

Verify the specific manufacturer part number against official TXC documentation to ensure compatibility with circuit requirements. Confirm that the 12 pF load capacitance matches the oscillator circuit design. Check datasheet specifications for ESR and drive level limits to prevent over-driving the crystal. Ensure the 4-SMD footprint aligns with the PCB layout guidelines provided in the official package drawings.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with ±30 ppm stability. The 12 pF load capacitance must match the system's external capacitor values. Consider the 60 Ohm ESR for impedance matching requirements. The -40°C to +85°C operating range suits industrial environments. Verify the 4-SMD package size fits the available board space constraints.

Crystals Part Context

This crystal belongs to the 7V series from TXC Corporation, which focuses on standard surface-mount quartz crystals. The series offers various frequencies and packages tailored for general-purpose timing needs. The 7V-25.000MAHE-T specifically addresses the common 25 MHz requirement found in many digital systems.

Crystals Replacement Considerations

Cross-reference with other 25 MHz crystals having 12 pF load capacitance and similar ESR values. Ensure replacement parts support the same 4-SMD package dimensions and operate within the -40°C to +85°C range. Verify frequency stability meets the ±30 ppm requirement.
