The Inputs page allows for modification of the LMK3H2108 input buffers. Each input consists of the following fields:

  • Input frequency: Used solely for calculation purposes on the output pages
  • Power state: Whether the input path is enabled or disabled
  • Input format: Disabled, INx_P LVCMOS, INx_N LVCMOS, or INx Differential
  • Input termination, capable of supporting any input format
  • Loss of signal behavior
  • PCIe Reset (PERST) mode behavior
