Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the system design specifications before procurement. Confirm that the 4-pad footprint matches the PCB layout guidelines provided in the official datasheet. Ensure compatibility with standard reflow soldering profiles for ceramic packaged components to maintain structural integrity and electrical performance.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required alongside moderate frequency stability of ±20 ppm. The 11 pF load capacitance must align with the oscillator circuit's input/output capacitance settings. Consider the -20°C to +70°C temperature range suitability for the intended operational environment compared to wider industrial or commercial alternatives.

Crystals Part Context

This part belongs to the SXT324 series of industrial-grade surface-mount crystals. The series is characterized by small form factors and improved noise immunity due to the four-pad ground configuration. Variants within the series differ primarily in frequency, load capacitance, tolerance grades, and specified operating temperature ranges.

Crystals Replacement Considerations

Direct replacements must match the 19.6608 MHz frequency, 11 pF load capacitance, 70 Ohm ESR, and 4-SMD no-lead package dimensions. Verify that substitute components offer equivalent ±20 ppm stability across the -20°C to +70°C range to ensure system timing accuracy is maintained without redesign.
