Board Information
CLKin Inputs
CLKin0 is one of two inputs that can be used to drive the LMK01000. Although this input is rated to higher
frequencies, the balun on the board is only rated to 400 MHz. Ensure CLKin_SELECT is set to CLKin0 when
using this input. If a higher frequency is required, above 400 MHz, then use CLKin1.
CLKin1 is very similar to CLKin0. If this input is driven single-ended, it is preferred to shunt CLKin1* to ground
with a capacitor, but this capacitor is not placed on the board. CLKin1 is currently configured to be fed by a
differential output, such as the output of the LMK03000C. Ensure that CLKin_SELECT is set to CLKin1 when
using this input.
