Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. Ensure ESD precautions are observed during handling due to device sensitivity. Confirm that the required loop filter components match the selected divider setting as specified in the application data sheet tables.

Application Specific Clock/Timing Selection Notes

Select the appropriate divider setting (NSL0-NSL2) based on the desired reference frequency to achieve the target 10.30–10.80 GHz output. Choose between Type 2 or Type 3 loop filters depending on phase noise requirements, ensuring correct interconnection of CPOUT and VTUNE pins for Type 2 configurations. Verify reference source phase noise meets the minimum requirements listed in the quick reference data.
