Programmable Oscillators Procurement Notes

This component is supplied as a blank oscillator programmed at the time of order. Customers must specify the required frequency in the order remarks or notes field during the purchasing process. Verification of the specific part number suffix ensures correct package dimensions and modulation type. Confirm that the requested frequency falls within the 670 kHz to 170 MHz operational range before finalizing procurement.

Programmable Oscillators Selection Notes

Select this model when downward spread spectrum modulation is required to minimize electromagnetic interference in sensitive circuits. Ensure the design accommodates the 4-SMD 3.2x2.5mm footprint and the 1.62V to 3.63V supply voltage constraints. Verify that the application environment stays within the -40°C to 105°C industrial temperature rating. Compare against other series variants if center spread or different package sizes are needed.

Programmable Oscillators Part Context

This part belongs to the SG-9101CE series of programmable spread spectrum crystal oscillators manufactured by EPSON. It shares the core technology with siblings like the SG-9101CE-C02PHCCA but differs in modulation direction and bandwidth. The series is designed for applications demanding precise clocking with reduced spectral noise, utilizing a standard crystal resonator base for stability.

Programmable Oscillators Replacement Considerations

Direct replacements include other SG-9101CE variants with identical package and voltage specs but different modulation types, such as SG-9101CE-C02PHCCA for center spread. Cross-series replacement requires verifying pin compatibility and electrical parameters.
