Crystals Procurement Notes

Verify the specific suffix 'M' against manufacturer documentation to confirm exact tolerance and packaging specifications. Ensure the 4-SMD footprint matches the target PCB layout dimensions. Confirm RoHS compliance status through official datasheets prior to integration into regulated product lines.

Crystals Selection Notes

Select this component when a 19.6608 MHz reference is required for UART or SPI baud rate generation. The 20 pF load capacitance must align with the oscillator circuit design. Consider the 70 Ohm ESR limits for drive level sensitivity in low-power applications.

Crystals Part Context

This part belongs to the SXT324 series of tuning fork crystals designed for high-frequency applications. Unlike lower-frequency watch crystals, this model targets data communication speeds requiring stable 19+ MHz signals. The series utilizes advanced thin-film technology for improved stability over temperature variations.

Crystals Replacement Considerations

Direct substitutes include other 19.6608 MHz crystals with identical 20 pF load capacitance and 4-SMD no-lead footprints. Verify that alternative manufacturers specify compatible ESR values near 70 Ohms to maintain oscillation reliability.
