Oscillators Procurement Notes

Verify the specific part number suffix against official ILSI documentation to confirm pinout configuration and tolerance grades. Ensure the procurement channel provides valid traceability for RoHS compliance status. Confirm that the delivered components match the 4-SMD no-lead package specification required for your PCB footprint. Request manufacturer datasheets to validate electrical parameters prior to assembly integration.

Oscillators Selection Notes

Select this component when a stable 40 MHz reference is required in space-constrained designs. The TCXO architecture compensates for temperature-induced drift, making it suitable for environments with significant thermal fluctuations. Verify that the HCMOS output voltage levels align with the input requirements of the target logic circuitry. Consider the 3 V supply constraint during power budget analysis.

Oscillators Part Context

This model belongs to the ILSI TCXO series, which focuses on providing high-stability oscillators for demanding electronic applications. The series typically features low phase noise and robust temperature compensation mechanisms. These components are engineered to replace discrete crystal and capacitor networks with integrated solutions, simplifying board layout and improving reliability in mass-produced electronics.

Oscillators Replacement Considerations

Cross-reference with other ILSI TCXO models offering 40 MHz frequency and similar package dimensions. Verify that any substitute maintains the same HCMOS output characteristics and 3 V supply requirements. Ensure the replacement component meets the -40 °C to +85 °C operating temperature range specified for the original part.
