Procurement Notes

Verify that the specific part number matches the required frequency specification, as this model is programmable. Confirm the supply voltage requirements align with your system design, noting the 1.62V to 3.63V operational range. Ensure the 4-SMD package dimensions fit your PCB layout constraints. Check for any specific programming instructions or order notes required by the distributor to set the desired frequency before shipment.

Selection Notes

Select this component when a small form factor and wide frequency programmability are required. Consider the ±20ppm stability if precise timing is critical. Evaluate the 8.1mA max current consumption against power budget constraints. The CMOS output is suitable for standard digital circuits. Verify thermal performance within the -40°C to 105°C range for your specific environment.

Part Context

This part belongs to the SG-8101 series of programmable crystal oscillators from EPSON. The series offers various package sizes and output types. The SG-8101CA variant specifically denotes the 2.5x2.0mm SMD package. This series is known for low jitter and high reliability, making it suitable for demanding electronic applications requiring stable clock signals.

Replacement Considerations

Direct substitutes include other SG-8101CG or SG-8101CA models from EPSON with compatible pinouts and electrical characteristics. Cross-referencing with similar programmable oscillators from other manufacturers requires careful verification of voltage, current, and stability specifications.
