MPC555 / MPC556
USER’S MANUAL
VDDSYN and VSSSYN are the PLL dedicated power supplies. These supplies must
be used only for the PLL and isolated from all other noisy signals in the board.
VDDSYN could be isolated with RC filter (see
noise allowed on VDDSYN, and VSSSYN is 50 mV with typical cut-off frequency of
500 Hz.
