Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the HCMOS output compatibility matches the receiving logic inputs of your target application to guarantee reliable signal integrity.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable/disable feature for power efficiency. It is appropriate for designs prioritizing small form factors due to its surface-mount construction. Consider alternative models if higher supply voltages or different output logic families are necessary for the specific circuit topology.

Oscillators Part Context

This part belongs to Aker Technology's series of ultra-miniature CMOS oscillators. These components are designed for wide temperature change environments and provide precise timing solutions. The manufacturer specializes in frequency control products for automotive, telecommunications, and data storage sectors, emphasizing reliability and compact packaging.

Oscillators Replacement Considerations

Direct substitutes must match the 40MHz frequency, 1.8V supply, HCMOS output, and 4-pin SMD package. Verify equivalent enable/disable pinout configurations and thermal performance characteristics to ensure functional parity without redesigning the host circuit board.
