Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm the exact frequency range and performance grade intended for the design. Ensure the WQFN-48 package thermal requirements are met during PCB layout. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when sub-picosecond jitter cleaning is required for frequencies up to 1.57 GHz. Compare against the LMK03001 series if higher output frequencies exceeding 1.57 GHz are necessary. Evaluate power consumption constraints as the device draws approximately 86 mA. Ensure the system requires nine differential outputs compatible with LVDS or LVPECL standards.
