To use the DCO shift controls on a given DPLL, enter the DCO ppb step value into the DCO Step Size (ppb) box shown below. The entered step size will be used to calculate a frequency deviation that will be applied to the DPLL numerator. This frequency deviation is shown in the DPLLx_FDEV control. To perform the shift, you must press the increment or decrement button.
