Procurement Notes

Verify the exact frequency specification and temperature grade required for your application before ordering, as these parameters vary significantly across the SG-8101CB series. Confirm that the supplier provides factory-programmed units or clear instructions for programming if applicable. Ensure the selected variant matches the required supply voltage range and package dimensions to guarantee compatibility with your PCB layout and power supply design.

Selection Notes

Select this component based on the specific frequency requirement and environmental operating conditions. Compare the available frequency tolerance options to ensure they meet the system's timing accuracy needs. Consider the power consumption characteristics relative to the system's battery life or thermal constraints. Verify that the CMOS output swing is compatible with the input requirements of the downstream logic components.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators from EPSON. The series is designed to offer flexibility in frequency selection while maintaining low power consumption and small form factors. It serves as a modern alternative to fixed-frequency oscillators, allowing designers to customize clock speeds during production or procurement phases.

Replacement Considerations

Direct replacements may include other SG-8101 variants with different suffixes indicating specific frequency or tolerance grades. Cross-referencing with similar programmable XO families from other manufacturers requires careful verification of pinout, voltage levels, and package dimensions to ensure functional equivalence.
