56. This specification is guaranteed by testing the PLL across the specified range using the IMO as the source for the PLL.
57. PLL input divider, Q, must be set so that the input frequency is divided down to the intermediate frequency range. Value for Q ranges from 1 to 16.
58. Based on device characterization (Not production tested).
