7.6 Main PLL and PLL Controller
This section provides a description of the Main PLL and the PLL Controller. For details on the operation of the PLL
Controller module, see the Phase Locked Loop (PLL) for KeyStone Devices User Guide in ‘‘Related Documentation
from Texas Instruments’’ on page 72.
The Main PLL is controlled by the standard PLL Controller. The PLL controller manages the clock ratios, alignment,
and gating for the system clocks to the device. Figure 7-9 shows a block diagram of the main PLL and the PLL
Controller.
