Oscillators Procurement Notes

Verify the exact frequency stability suffix (e.g., -R for ±50ppm) against the required specification sheet. Confirm the operating temperature range matches the application environment, as variants exist for commercial and extended ranges. Ensure the supply voltage requirement aligns with the target circuit's power rails, specifically checking for 1.8V or 3.3V compatibility. Cross-reference the pinout diagram with the PCB footprint to guarantee correct orientation during assembly.

Oscillators Selection Notes

Select this component when a low-profile HCMOS oscillator with enable control is required for space-constrained designs. Consider the specific stability tolerance needed for the clock source; tighter tolerances may require different suffixes within the same series. Evaluate the load capacitance requirements of the receiving input stage. Compare power consumption metrics if battery life is a critical constraint in the portable application context.

Oscillators Part Context

This part belongs to Aker Technology's ultra-miniature CMOS and differential XO series. These oscillators are designed for wide temperature change environments and offer precise timing solutions. The S218025T series represents a compact form factor suitable for modern high-density electronics manufacturing processes requiring small footprints and reliable performance.

Oscillators Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, HCMOS output, and 4-SMD no-lead package. Verify that alternative vendors provide equivalent enable/disable functionality and similar physical dimensions. Check for compatible supply voltage ranges and frequency stability specifications before integration.
