Oscillators Procurement Notes

Verify the specific suffix 'IMR' against the manufacturer's datasheet to confirm the exact voltage tolerance and temperature grade, as variations exist within the CA25 series. Ensure that the 1.8V supply requirement aligns with the target system design, as some variants in this family operate at 2.5V. Confirm lead times with authorized distributors, as availability may vary due to automotive supply chain constraints. Cross-reference the AEC-Q200 certification status if strict automotive compliance is required for the final assembly.

Oscillators Selection Notes

Select the CA25C0404IMR when a 4 MHz clock source is required for automotive or industrial environments with strict size limitations. This model is appropriate for designs needing low standby current via the enable pin. Compare against other CA25 variants if higher frequencies or different voltage levels are needed. Consider the ±30 ppm stability sufficient for most synchronous digital interfaces. Verify that the 4-SMD package matches the PCB footprint and reflow soldering profile capabilities of the manufacturing process.

Oscillators Part Context

This component belongs to the CA25 series of standard clock oscillators from CTS-Frequency Controls. The series is specifically engineered for automotive and industrial markets, emphasizing durability and precision. The CA25C0404IMR represents a specific configuration within this line, offering a 4 MHz output in a small form factor. It shares common characteristics with other members of the series, such as the enable feature and AEC-Q200 qualification, but differs in frequency and electrical parameters.

Oscillators Replacement Considerations

CA25C0404GMR is a parameter-equivalent alternative from CTS-Frequency Controls. CA25C0404INR is another variant within the same series that may serve as a substitute depending on voltage compatibility.
