Crystals Applications

• Clock signal generation for microprocessors and digital logic circuits
• Timing reference sources for communication interfaces such as UART and SPI
• Frequency control in consumer electronics requiring precise synchronization

Crystals Procurement Notes

Verify the specific ESR value of 50 Ohms against your circuit design requirements, as variations exist within the SXT3248DD38 series. Confirm that the 8 pF load capacitance aligns with your oscillator IC specifications. Ensure the 4-SMD no-lead footprint matches your PCB layout dimensions. Check RoHS compliance status if required by your manufacturing standards. Validate the ±20 ppm stability meets your system's timing accuracy constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz frequency is specifically required for clocking applications. Consider the 50 Ohm ESR and 8 pF load capacitance to ensure compatibility with your existing oscillator circuit design. The ±20 ppm stability is suitable for general-purpose digital systems but may not suffice for high-precision RF applications. Evaluate the 4-SMD package size against available board real estate. Compare against other frequencies in the SXT3248DD38 series if alternative timing speeds are needed.

Crystals Part Context

This part belongs to the SXT3248DD38 series of surface-mount crystals from Suntsu Electronics, Inc. The series offers various frequency options including 19.2 MHz, 25 MHz, 30 MHz, and 32 MHz, all sharing similar package and electrical characteristics. Variations in ESR values exist across the series, ranging from 35 Ohms to 100 Ohms depending on the specific frequency. This 27 MHz variant provides a middle-ground ESR specification compared to higher-frequency counterparts.

Crystals Replacement Considerations

Direct substitutes include other SXT3248DD38 variants with identical 4-SMD packages, provided the ESR and load capacitance match. Verify that any replacement maintains the 27 MHz frequency and ±20 ppm stability. Cross-reference pinout and footprint dimensions to ensure mechanical compatibility. Consult manufacturer datasheets for updated specifications before substitution.
