Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for your manufacturing process. Confirm RoHS compliance status through the official datasheet as regulatory requirements may vary by region. Ensure the selected variant matches the required temperature grade and load capacitance specifications for your circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental mode crystal is preferred over overtone modes for lower phase noise characteristics. The 12 pF load capacitance must match the oscillator circuit's external capacitors to achieve the specified ±30 ppm accuracy. Consider the 100 Ohm ESR limit to ensure sufficient loop gain in the driving circuitry while maintaining low power consumption.

Crystals Part Context

This part belongs to the TXC 7M series of ceramic-packaged quartz crystals. The series offers various frequency options within standard SMD footprints. The 7M designation typically denotes a specific package style and mounting configuration optimized for high-volume surface-mount technology production lines in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 14.7456 MHz crystals in 3225 packages with matching 12 pF load capacitance and ±30 ppm tolerance. Verify that alternative parts meet the same 100 Ohm ESR maximum and 10 uW drive level limits to ensure circuit compatibility without redesign.
