Programmable Oscillators Procurement Notes

This component is supplied in tubes and requires specific frequency programming during the ordering process. Buyers must input the desired frequency value in the order remarks when purchasing through authorized distributors such as DigiKey. Verification of the programming confirmation is essential before production integration to ensure the delivered unit matches the target clock specifications. Confirm that the selected variant aligns with the required voltage and temperature ratings for the intended application environment.

Programmable Oscillators Selection Notes

Select this model when design requirements demand active spread spectrum capabilities to meet strict EMC standards without external filtering components. The CMOS output interface ensures compatibility with standard digital logic families. Consider the 4-SMD package size for space-constrained PCB layouts. Ensure the system power supply remains stable within the 1.62V to 3.63V window to maintain oscillation integrity. Verify that the programming tool, such as SG-Writer II, is available for final configuration if custom frequencies are needed beyond standard offerings.

Programmable Oscillators Part Context

The SG-9101 series represents EPSON's line of programmable spread spectrum crystal oscillators. This specific CE variant belongs to the industrial grade segment, offering robust performance across wide temperature ranges. The series distinguishes itself by allowing designers to tailor the spread spectrum parameters, including modulation curves and bandwidth, to optimize EMI reduction for specific circuit designs. It serves as a direct replacement for fixed-frequency oscillators where noise mitigation is critical.

Programmable Oscillators Replacement Considerations

Direct substitutes include other SG-9101CE variants with different frequency or package configurations, provided the pinout and electrical characteristics remain compatible. Cross-model replacements from the same family require verification of the spread spectrum type and voltage levels. Ensure any alternative part supports the same 4-SMD footprint and CMOS output drive capability to maintain board layout integrity.
