Oscillators Procurement Notes

Verify the specific supply voltage variant (1.8V vs 3.3V) as datasheets may list multiple options. Confirm the exact package dimensions against the mechanical drawing. Check for End-of-Life status or production discontinuation notices from TXC Corporation before finalizing design-in decisions. Ensure compatibility with existing PCB footprint and reflow profiles.

Oscillators Selection Notes

Select this component when a 74.25 MHz CMOS signal is required in a small SMD package. Consider the MEMS construction for vibration resistance compared to quartz alternatives. Evaluate the enable/disable pin requirement if power saving is necessary. Verify that the 50 ppm stability meets system timing tolerances across the full operating temperature range.
