Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 2.5V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications. Check for any specific handling instructions regarding surface-mount reflow profiles to maintain component integrity during assembly processes.

Oscillators Selection Notes

Select this component when a low-cost, standard CMOS oscillator with enable control is required for 4 MHz applications. Consider the 2.5V supply constraint and the -40°C to 85°C operating range. Evaluate if the 4-SMD package size fits within the available board space constraints compared to larger ceramic packages found in other series.

Oscillators Part Context

This part belongs to the ISM97 series of surface-mount oscillators from ILSI. The series offers various frequency options within the same package form factor. The 'AH' suffix typically denotes specific electrical characteristics or packaging variations within the product line. It serves as a timing reference solution for compact digital designs requiring standard CMOS outputs.

Oscillators Replacement Considerations

Direct substitutes may include other 4MHz CMOS oscillators in 4-SMD packages with 2.5V operation. Verify pinout compatibility and electrical parameters such as jitter and stability before substitution. Cross-reference with ILSI's ISM91 or ISM92 series if different package sizes are acceptable.
