Programmable Oscillators Procurement Notes

Verify the specific order suffix to confirm the down spread characteristic and frequency range. Ensure the target application requires the 1.62V to 3.63V supply voltage compatibility. Confirm that the 4-SMD package dimensions fit the PCB layout constraints. Check for any specific programming requirements if the part is not pre-configured at the factory.

Programmable Oscillators Selection Notes

Select this model when down spread modulation is required to minimize EMI in automotive safety systems. Compare against center spread variants if different spectral characteristics are needed. Ensure the operating temperature range meets the environmental conditions of the installation site. Verify that the CMOS output level is compatible with the receiving logic circuitry.

Programmable Oscillators Part Context

This component belongs to the SG-9101 series of programmable spread spectrum crystal oscillators designed for automotive applications. The series is engineered to support driving safety systems such as engine control and airbag modules. The CE suffix typically denotes specific spread spectrum characteristics, distinguishing it from other variants in the family.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101 series parts with matching spread spectrum types. Verify pinout and package compatibility before swapping. Ensure the replacement maintains the same supply voltage and output drive capabilities.
