Programmable Oscillators Procurement Notes

This component is manufactured as a blank oscillator requiring specific frequency programming by the distributor during the ordering process. Customers must input their required frequency in the website order remarks to ensure correct configuration. The item is classified as made-to-order and typically cannot be cancelled or returned once the request is submitted. Verify that the requested frequency falls within the supported 670 kHz to 20 MHz range before finalizing the purchase.

Programmable Oscillators Selection Notes

Select this model when a standard XO form factor is required with customizable frequency output. The downward spread spectrum feature makes it suitable for applications sensitive to EMI. Ensure the design accommodates the 1.62V to 3.63V supply range and utilizes the 4-SMD footprint. This part is appropriate for systems needing precise timing with reduced spectral noise compared to fixed-frequency oscillators.

Programmable Oscillators Part Context

The SG-9101CG-D05PGDAC belongs to the SG-9101Cx series of programmable spread spectrum crystal oscillators. This series is designed to offer flexibility in frequency selection while maintaining low jitter performance. The 'D' suffix indicates downward spread spectrum modulation, distinguishing it from center-spread variants. The 'C' denotes the commercial temperature grade, ensuring stability for general-purpose electronic equipment.

Programmable Oscillators Replacement Considerations

Direct replacements within the same series include SG-9101CG-C05PGCAA for center-spread spectrum requirements. Other models in the SG-9101 family may share similar footprints but differ in modulation type or frequency limits. Verify that any substitute matches the CMOS output level and voltage specifications to maintain circuit compatibility.
