Programmable Oscillators Procurement Notes

Verify that the specific part number matches the required spread spectrum type, as suffixes indicate distinct modulation profiles such as center or down spread. Confirm the operating temperature grade aligns with the application environment, noting differences between industrial and extended ranges. Ensure the programming requirements are understood, as these devices often require specific ordering procedures to define the target frequency during manufacturing. Check package compatibility against the PCB footprint specifications before finalizing procurement orders.

Programmable Oscillators Selection Notes

Select this component when precise frequency agility is required alongside electromagnetic compatibility improvements. The center spread spectrum feature makes it suitable for applications where reducing peak spectral density is critical. Consider the supply voltage constraints to ensure compatibility with the system's power rails. Evaluate the thermal performance requirements to determine if the -40°C to 105°C range meets the operational conditions. Verify that the CMOS output swing is compatible with the receiving logic levels of the connected circuitry.

Programmable Oscillators Part Context

This model belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. The series is designed to offer flexibility in frequency selection while providing built-in EMI mitigation capabilities. These oscillators replace fixed-frequency crystals in designs requiring variable timing references. The SG-9101CE variant specifically denotes the industrial temperature grade version of the family.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101 series variants with matching package and electrical characteristics. Verify that alternative models support the same center spread spectrum profile and frequency range. Ensure the replacement maintains the same supply voltage and output logic standards. Cross-reference the pinout configuration to guarantee board-level compatibility without redesigning the footprint.
