Programmable Oscillators Procurement Notes

Verify the specific part number suffix against official EPSON documentation to ensure correct package type and electrical characteristics. Confirm that the required frequency falls within the supported 670 kHz to 20 MHz range. Check for automotive qualification requirements if deploying in safety-critical environments such as ECU or airbag systems. Ensure supply voltage compatibility with the 1.62V to 3.63V operational window before integration.

Programmable Oscillators Selection Notes

Select this component when low electromagnetic interference is critical due to its downward spread spectrum feature. Choose this model for applications requiring precise timing within the specified frequency range and robust performance across wide industrial temperature variations. Consider the small surface-mount footprint for space-constrained designs. Verify that the CMOS output interface aligns with the target logic levels of the receiving circuitry.
