Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact frequency combination and stability grade. Confirm that the required output frequencies match the pre-programmed options available for this part number. Ensure the operating environment falls within the specified industrial temperature range of -40°C to +85°C. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when high reliability under mechanical stress is required due to its MEMS construction and MIL-STD-883 qualification. Choose based on the necessary frequency stability tolerance, which is defined by the middle digit in the ordering code. Verify that the required output frequencies are supported by the pre-programmed memory configurations. Consider the separate supply voltage requirement for each LVDS output if signal isolation is critical for the design.
