... Freescale Semiconductor, Inc. MPC9229 S_CLOCK S_DATA S_LOAD M[8: N[1:0] P_LOAD Power Supply Filtering The MPC9229 is a mixed analog/digital product. Its analog circuitry is naturally susceptible to random noise, especially if this noise is seen on the power supply pins. Random noise on the VCC_PLL pin impacts the device characteristics. The MPC9229 provides separate power supplies for the digital circuitry (VCC) and the internal PLL (VCC_PLL) of the device ...
