• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'AH' against official ILSI documentation to confirm the exact frequency tolerance and package variant. Ensure the target design supports 3.3V logic levels and requires enable/disable control. Confirm that the 4-SMD no-lead footprint matches the PCB layout specifications. Cross-reference the ±25ppm stability requirement with system timing constraints before finalizing procurement.

Oscillators Selection Notes

Select this model when a stable 14.31818 MHz reference is required in a low-profile surface-mount format. The 3.3V operation makes it suitable for modern low-voltage digital designs. Consider the ±25ppm stability for general timing applications rather than high-precision RF requirements. The enable feature allows for dynamic power control in battery-operated or energy-efficient systems.

Oscillators Part Context

This component belongs to the ISM97 series of surface-mount oscillators from ILSI. The series offers various frequencies and package sizes. The AH suffix typically denotes specific electrical characteristics such as stability and package type within the product line. It serves as a direct replacement for other standard CMOS oscillators in similar form factors.

Oscillators Replacement Considerations

Check pinout compatibility and voltage levels when substituting with other 14.31818 MHz oscillators. Verify that alternative parts support the same 3.3V supply and enable functionality. Ensure the replacement maintains the required ±25ppm stability and operates within the -40°C to +85°C temperature range.
