LMK1D1204: LMK1D1204 input related issues

Part Number: LMK1D1204


The input of LMK1D1204 is a 1GHz differential clock output by a phase-locked loop, Sine wave, is input feasible?


  • Hi Jeno, 

    As long as the input meets all of the requirements in the Electrical Characteristics section of the datasheet, there shouldn't be any issues. One of the main drawbacks of using a sine wave input is the relatively slow slew rate which could impact phase noise performance, but at higher frequencies like 1GHz this isn't a concern. Let me know if you have any other questions.
