Oscillators Procurement Notes

Verify the specific suffix codes against the official ILSI datasheet to confirm exact electrical parameters such as frequency stability, load capacitance, and operating temperature range. Ensure the ordering code matches the required package type and lead finish specifications. Cross-reference the RoHS compliance status and availability status directly with authorized distributors or the manufacturer's current product announcements to avoid obsolete or non-compliant inventory.

Oscillators Selection Notes

Select this component when a compact SMD form factor is required alongside standard CMOS drive strength. Consider the 2.5 mm x 3.2 mm package dimensions for board space optimization. Evaluate the enable pin requirement if dynamic power control is necessary for the application. Confirm that the 60 MHz frequency aligns with the system clock requirements and that the jitter specifications meet the signal integrity needs of the connected peripherals.
