Oscillators Procurement Notes

Verify the specific suffix requirements against the manufacturer's current documentation to ensure correct packaging and tolerance specifications. Confirm that the HCMOS output voltage levels align with the target system's logic thresholds. Ensure the selected variant meets the required operating temperature range for the intended deployment environment. Cross-reference the part number with official distributor catalogs to validate availability and authenticity before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 12.288 MHz reference is required for digital communication protocols such as Ethernet or USB. The ±25 ppm stability suits general timing applications where tighter tolerances are unnecessary. Consider the enable pin feature if dynamic power saving is a design priority. Evaluate the 3.2x2.5mm footprint against PCB layout constraints to ensure adequate spacing for thermal dissipation and assembly accuracy during surface mount processing.
