Procurement Notes

Verify the specific frequency configuration required for your application, as this component is programmable. Confirm that the 4-SMD package dimensions align with your PCB footprint constraints. Ensure the supply voltage range matches your system's power rails. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Validate that the CMOS output swing is compatible with your downstream logic levels.

Selection Notes

Choose this model when design flexibility is prioritized over fixed-frequency components to reduce inventory complexity. Consider the ±50 ppm stability specification against your system's jitter tolerance requirements. Evaluate the 1.62V to 3.63V operating range to ensure it covers your lowest and highest voltage scenarios. Assess the need for standby functionality to determine if power savings justify the potential cost difference compared to non-programmable alternatives.

Part Context

This component belongs to the SG-8101 series of programmable oscillators from EPSON, which are engineered for versatility in modern embedded designs. The series replaces traditional fixed-frequency crystals, allowing engineers to adjust parameters post-production.
