Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current datasheet before procurement. Ensure that the 1.8V supply requirement aligns with the target system's power architecture. Confirm that the HCMOS output voltage levels are compatible with the receiving logic inputs to prevent signal integrity issues or potential damage during integration.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 32.768 kHz timing applications. The 1.8V supply voltage makes it suitable for modern low-voltage digital systems. Consider the ±25 ppm stability specification against the system's timing accuracy requirements. The enable/disable feature allows for power management strategies in battery-operated devices.

Oscillators Part Context

This part belongs to Aker Technology Corp's line of standard crystal oscillators designed for general-purpose timing applications. The S518025T series typically offers various frequency options within a standardized footprint. The 32.768 kHz frequency is a industry standard derived from binary division of higher frequencies, commonly used for calendar and timekeeping functions in microcontroller-based designs.

Oscillators Replacement Considerations

Direct replacements must match the 32.768 kHz frequency, 1.8V supply, HCMOS output, and 4-SMD package dimensions. Verify that substitute components offer equivalent ±25 ppm stability and operate within the -40°C to 85°C temperature range. Check for identical enable/disable pin configurations if power control is utilized in the circuit design.
