Crystals Procurement Notes

Verify the specific suffix 'EQ' against official TXC documentation to confirm pinout orientation and soldering pad requirements. Ensure the selected variant matches the required load capacitance of 10 pF for the target circuit design. Confirm availability status as distribution data may vary. Cross-reference the package dimensions with the PCB footprint library to prevent assembly errors during production.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±10 ppm stability is required for 14.7456 MHz applications. The 10 pF load capacitance must match the oscillator circuit design parameters. Consider the -20°C to +70°C operating range for standard commercial environments. The 40 Ohm ESR value should be compatible with the driving circuit's impedance requirements. Verify that the 3.2x2.5 mm package fits the available board space constraints.
