Procurement Notes

This component is supplied as a blank oscillator that requires frequency programming at the time of order. Buyers must specify the desired operating frequency in the order remarks or notes field during the purchasing process. Verification of the programming request details is essential to ensure the delivered unit matches the system requirements. Confirm that the selected frequency falls within the valid operational range of 670 kHz to 170 MHz before finalizing the procurement.

Selection Notes

Select this model when design flexibility regarding clock frequency is required without maintaining multiple inventory SKUs. Ensure the application environment stays within the specified -40°C to 85°C operating temperature range. Verify that the system power supply remains stable between 1.62V and 3.63V to guarantee correct operation. Consider the 4-SMD package dimensions if board space is constrained. Confirm that CMOS output levels are compatible with the receiving logic inputs.

Part Context

The SG-9101CG series represents EPSON's line of programmable spread spectrum crystal oscillators designed for applications demanding both timing precision and electromagnetic compatibility. This specific variant belongs to the CG sub-series, indicating specific performance characteristics regarding noise and stability. The series is engineered to replace fixed-frequency crystals in modern designs where frequency agility and EMI mitigation are critical design constraints.

Replacement Considerations

Direct replacements may include other models from the SG-9101CG family, such as SG-9101CG-D40PGACA or SG-9101CG-D40SHAAC, provided they support the same package and electrical specifications. Verify that any substitute part also offers programmable frequency options and downward spread spectrum functionality. Cross-reference pinouts and voltage tolerances to ensure compatibility with the existing circuit design.
