Procurement Notes

Verify that the specific part number matches the required frequency specification, as this model represents a fixed-frequency variant within the programmable series. Confirm the package dimensions align with the PCB footprint requirements. Ensure the supply voltage range meets the system's power rail specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a standard CMOS output is required for frequencies up to 20 MHz. The wide operating temperature range makes it suitable for industrial environments. Consider the downward spread spectrum feature if electromagnetic interference reduction is a priority. The small surface-mount package is ideal for space-constrained designs. Verify that the standby current consumption fits the system's power budget during inactive states.

Part Context

This oscillator belongs to the SG-9101CG series, which offers programmable crystal oscillators with spread spectrum capabilities. The series is designed for applications requiring flexible frequency selection and low noise performance. The SG-9101CG-D40SHACC specifically denotes a configuration with a 20 MHz output and downward spread spectrum characteristics. It shares the same physical package and electrical interface as other variants in the family, differing primarily in programmed frequency and spectral modulation settings.
