Procurement Notes

Verify the specific optical option suffix (OPT 002) matches project requirements. Confirm that the 3.3 V supply voltage aligns with system power rails. Ensure through-hole mounting compatibility with the target PCB layout. Check for non-cancellable and non-returnable status before finalizing orders. Validate current production availability directly with the manufacturer or authorized distributors.

Selection Notes

Select this component when high stability and low phase noise are critical for system timing. Consider the 10 MHz fixed frequency output against application needs. Evaluate the 3.3 V operating voltage against available power supplies. Assess the through-hole package size for mechanical fit within the enclosure. Compare radiation tolerance specifications if used in space-grade environments.
