Crystals Procurement Notes

Verify the specific suffix 'D' against the official TXC datasheet to confirm the exact frequency tolerance and temperature range specifications, as variations exist within the 7V series. Ensure the selected variant matches the required 10 pF load capacitance and 100 Ohm ESR parameters for the target circuit design. Confirm RoHS compliance status prior to final procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±20 ppm stability is required for 14.7456 MHz applications. The 10 pF load capacitance aligns with standard CMOS oscillator inputs. Consider the -20°C to +70°C operating range for commercial-grade environments. The 4-SMD footprint offers space efficiency compared to through-hole alternatives like HC-49 packages.

Crystals Part Context

This part belongs to the TXC 7V series of ceramic-packaged quartz crystals. The series is characterized by small form factors and lead-free construction. The 7V-14.7456MDDQ-T specifically denotes the 14.7456 MHz frequency point with the D suffix indicating the ±20 ppm tolerance class within this product line.

Crystals Replacement Considerations

Cross-reference other manufacturers offering 14.7456 MHz crystals in 3.2x2.5mm SMD packages with 10pF load capacitance. Verify that substitute parts maintain identical ESR values and frequency stability requirements.
