NOTE
PLLM[5:0] bits of the multiplier are controlled by the PLLM register inside the PLL controller
and PLLM[12:6] bits are controlled by the chip-level MAINPLLCTL0 register. The complete
13-bit value is latched when the GO operation is initiated in the PLL controller. Only
PLLDIV2, PLLDIV5, and PLLDIV8 are programmable on the C6654 and C6652 devices. See
the Phase-Locked Loop (PLL) for KeyStone Devices User's Guide for more details on how to
program the PLL controller.
The multiplication and division ratios within the PLL and the post-division for each of the chip-level clocks
are determined by a combination of this PLL and the PLL controller. The PLL controller also controls reset
propagation through the chip, clock alignment, and test points. The PLL controller monitors the PLL status
and provides an output signal indicating when the PLL is locked.
Main PLL power is supplied externally through the Main PLL power-supply pin (AVDDA1). An external
EMI filter circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices
for detailed recommendations. For the best performance, TI recommends placing all the PLL external
components on one side of the board without jumpers, switches, or components other than those shown.
For reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external
components (C1, C2, and the EMI Filter).
The minimum SYSCLK rise and fall times should also be observed. For the input clock timing
requirements, see Section 5.7.4.
NOTE
The PLL controller as described in the Phase-Locked Loop (PLL) for KeyStone Devices
User's Guide includes a superset of features, some of which are not supported on the C6654
and C6652 devices. The following sections describe the registers that are supported; it
should be assumed that any registers not included in these sections is not supported by the
device. Furthermore, only the bits within the registers described here are supported. Avoid
writing to any reserved memory location or changing the value of reserved bits.
