• LMX2615-SP: Can PLL_NUM exceed PLL_DEN?

  

  Edwin Grigorian

  Resolved

  Part Number: LMX2615-SP Tool/software: Does the LMX2615 automatically increment PLL_N whenever PLL_NUM is greater than PLL_DEN, or is it necessary for the controlling device to ensure that PLL_NUM always stays below PLL_DEN? Ref. Eqn: f_VCO = f_PD …

  Joseph Sanchez

  Resolved

  Part Number: LMX2615-SP Tool/software: The Datasheet mentions to terminate an unused RF output but also shows that you can shut down the unused output via SPI control which would seem to make the termination irrelevant. We plan to shut down the unused…
