Programmable Oscillators Procurement Notes

This component is supplied as a blank oscillator that requires frequency programming before use. Customers must specify the desired frequency during the ordering process through authorized distributors such as DigiKey. Verification of the programming status and final frequency accuracy is essential prior to integration into the target circuit to ensure compliance with system timing specifications.

Programmable Oscillators Selection Notes

Select this model when a small form factor and programmable frequency are required for EMI reduction. The CE suffix indicates a specific package and performance variant within the SG-9101 series. Ensure the application voltage falls within the 1.62V to 3.63V range and verify that the 4-SMD footprint matches the PCB layout constraints.

Programmable Oscillators Part Context

The SG-9101CE-C20SHCAC belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. This series is engineered to provide customizable clock solutions with integrated EMI suppression capabilities. The CE variant specifically denotes the 2520 package size and industrial temperature grade, distinguishing it from other series members like the CG or CA variants which may differ in size or automotive qualification.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101 series models such as SG-9101CG-C10SHCAC or SG-9101CE-C20SHAAC, provided they match the required frequency range and package dimensions. Verify that any replacement part supports the same CMOS output type and spread spectrum configuration to maintain system electromagnetic compatibility.
