Crystals Procurement Notes

Verify the specific suffix 'M' corresponds to the required tape-and-reel or bulk packaging format as defined by the manufacturer's official documentation. Confirm that the ±30 ppm tolerance meets the system's jitter and stability requirements before finalizing procurement orders. Ensure compatibility with the 12 pF load capacitance specification in the target circuit design to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with moderate precision. The 100 Ohm ESR value influences drive level sensitivity; ensure the driving circuitry adheres to the manufacturer's recommended excitation power limits. Compare against alternative frequencies if the application requires different baud rates or clock divisions. Validate that the 4-SMD footprint matches the PCB land pattern guidelines provided in the datasheet.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT series of surface-mount crystals. Similar variants include the SXT11412BA48-30.000M, which offers a 30 MHz frequency option with identical package dimensions and electrical characteristics. The series generally supports various standard frequencies while maintaining consistent mechanical profiles for board space optimization.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package. Verify ESR values near 100 Ohms to prevent overdriving issues. Cross-reference pinout configurations if using third-party equivalents to ensure correct solder joint formation.
