Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 45.578 MHz specification. Confirm voltage requirements align with the 1.8V to 3.3V operating range. Ensure the 4-SMD footprint dimensions are compatible with the PCB layout. Check RoHS compliance status if environmental regulations apply. Validate the package type against assembly capabilities.

Oscillators Selection Notes

Select this component when a precise 45.578 MHz reference is needed with low power consumption. Consider the ±15 ppm stability for applications tolerant of minor frequency drift. Evaluate the CMOS output level against input thresholds of downstream logic. Assess the thermal performance within the specified -40°C to +85°C range. Compare size constraints against available board space.

Oscillators Part Context

This part belongs to the SG-8101 series of standard oscillators from Epson Timing. The series offers various frequencies and packages. The SG-8101CE variant specifically denotes the CMOS output and voltage range. It is distinct from other series like SG-8018 or SG-3320 which may have different electrical characteristics or pinouts.

Oscillators Replacement Considerations

Direct substitutes must match the 45.578 MHz frequency, 4-SMD 3.2x2.5mm package, and CMOS output. Verify equivalent stability and voltage ranges. Cross-reference with Epson's official replacement list for any updated revisions.
