Procurement Notes

Verify the exact frequency requirement during ordering as this model is programmable. Confirm that the -40 suffix aligns with the necessary spread spectrum bandwidth specifications. Ensure the CMOS output type matches the receiving circuit's logic levels. Check RoHS3 compliance status if environmental regulations apply to your manufacturing process. Validate the operating temperature range against your system's thermal profile before finalizing procurement.

Selection Notes

Choose this oscillator when precise frequency agility and EMI reduction are critical. The downward spread spectrum feature helps minimize peak emissions. The wide supply voltage range allows flexibility in power design. Consider the small footprint for dense PCB layouts. Ensure the CMOS output drives the load capacitance correctly without additional buffering.

Part Context

This component belongs to the SG-9101CG series of programmable oscillators. The series is designed for applications needing flexible frequency settings and spread spectrum capabilities. Other variants in the family may offer different frequency ranges or output types. The D40SHDBC suffix indicates specific programming parameters including the 20 MHz target and spread spectrum characteristics.

Replacement Considerations

Direct substitutes include other SG-9101CG models with matching frequency and package dimensions. Verify that any replacement maintains the same CMOS output and voltage range. Check if alternative parts support the required -4.00% spread spectrum bandwidth. Ensure thermal performance remains within the -40°C to +105°C specification.
