Figure 6-5. PLL Input Clock
As shown in
Figure 6-5
, the PLL1 controller features a software-programmable PLL multiplier controller
(PLLM) and five dividers (PREDIV, D1, D2, D3, D4, D5, D6). The PLL1 controller uses the device input
clock CLKIN1 to generate a system reference clock (SYSREFCLK) and five system clocks (SYSCLK1,
SYSCLK2, SYSCLK3, SYSCLK4, SYSCLK5 and SYSCLK6). PLL1 power is supplied externally via the
PLL1 power-supply pin (PLLV1). An external EMI filter circuit must be added to PLLV1, as shown in
Figure 8-11. The 1.8-V supply of the EMI filter must be from the same 1.8-V power plane supplying the I/O
power-supply pin, D
VDD18
. TI requires EMI filter manufacturer Murata, part number NFM18CC222R1C3.
