• Supports flexible programming via the SG-Writer II tool, allowing designers to adjust frequency and spread spectrum parameters for specific circuit requirements.
• Features a compact surface-mount package suitable for space-constrained designs while maintaining industrial-grade thermal performance.

Programmable Oscillators Applications

• Automotive electronic systems requiring high electromagnetic compatibility.
• Communication equipment needing reduced signal noise and interference.
• Computer peripherals and general-purpose digital circuits.

Programmable Oscillators Procurement Notes

This component is available through authorized distributors such as DigiKey. As a programmable device, it may require specific ordering instructions or post-order programming services to set the desired frequency. Verify the exact lead time and availability status directly with the supplier before placing orders, as stock levels can vary. Ensure that the required spread spectrum configuration aligns with the distributor's programming capabilities.

Programmable Oscillators Selection Notes

Select this model when EMI reduction is critical in dense electronic environments. The SG-9101CE variant provides a balance of low power consumption and compact size. Designers must account for the need to program the specific frequency and modulation profile using official Epson tools. Consider the 4-SMD package dimensions for PCB layout constraints and verify voltage compatibility with the target system logic levels.

Programmable Oscillators Part Context

The SG-9101CE-C20SGDCA belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. This series is engineered to address electromagnetic interference challenges in modern electronics by spreading the energy of the clock signal over a wider frequency band. The CE suffix typically denotes specific package and feature configurations within the broader product family.

Programmable Oscillators Replacement Considerations

Direct replacements should be sought from the same SG-9101 series with compatible package dimensions and electrical specifications. Verify that any substitute part supports the required frequency range and spread spectrum functionality. Cross-model substitution requires careful evaluation of pinout compatibility and programming tool support.
