AC characteristics apply for parallel output termination of 50
PLL mode requires PLL_EN = 0 to enable the PLL and zero-delay operation.
In bypass mode, the MPC9608 divides the input reference clock.
Applies for bank A and for bank B if BSEL = 0. If BSEL = 1, the minimum and maximum output frequency of bank B is divided by two.
