PLL configuration registers (address 0x52; 0x53; 0x54; 0x55;
0x56; 0x57)
By default, the STA381BWS is able to configure the embedded PLL automatically
depending on the MCS bits (reg 0x00). For certain applications and to provide flexibility to
the user, a manual PLL configuration can be used (setting PLL_DIRP to ‘1’)
The output PLL frequency formula is:
where Fin is the input clock frequency from the pad.
