The secondary PLL controller generates interface clocks for the DDR2 memory controller.
As shown in
Figure 6-7
, the PLL2 controller features a PLL multiplier controller. The PLL multiplier is fixed
to a x20 multiplier rate. PLL2 power is supplied externally via the PLL2 power supply (PLLV2). An external
PLL filter circuit must be added to PLLV2 as shown in
Figure 6-7
. The 1.8-V supply for the EMI filter must
be from the same 1.8-V power plane supplying the I/O power-supply pin, DVDD18. TI requires EMI filter
manufacturer Murata, part number NFM18CC222R1C3.

All PLL external components (C161, C162, and the EMI Filter) should be placed as close to the C64x+
