Procurement Notes

Verify the specific ordering code against official Epson documentation to ensure correct frequency and tolerance specifications. Confirm that the required load capacitance matches the system design requirements before procurement. Check for any recent updates to the component's mechanical dimensions or electrical characteristics in the latest datasheet revisions to guarantee compatibility with existing board layouts.

Selection Notes

Select this component when a stable 40 MHz reference signal is required within a 3225 footprint. Ensure the application environment stays within the specified -40°C to +85°C operational range. Consider the CMOS output drive capability to match downstream logic levels without additional buffering. Validate power supply voltage requirements against the system's available rails to prevent overvoltage conditions.

Part Context

This model belongs to Epson's SG-9101 series of ultra-low phase noise oscillators. The series is designed for applications demanding high frequency accuracy and long-term stability. The CG suffix typically denotes specific packaging and tape-and-reel options. This particular variant integrates necessary passive components internally to simplify the surrounding circuit design.

Replacement Considerations

Direct replacements must match the 40 MHz frequency, 3225 package size, and CMOS output type. Verify equivalent stability and temperature range specifications from alternative manufacturers. Cross-reference pin configurations and electrical parameters to ensure functional compatibility without redesigning the host circuit.
