• RE: LMK04816: Generating 125 MHz and 150 MHz from the same LMK04816 part.

  

  Derek Payne

  Resolved

  Hi Doug, The least common multiple of 150 MHz and 125 MHz is 750 MHz, so you will need a multiple of 750 MHz to generate both frequencies. There is no multiple of 750 MHz in the 2370-2600 range. So your assumption is correct, the VCO range on the LMK04816…
