... MPC9229 itself. However the PLL bypass mode may be of interest at the board level for functional debug. When T[2:0] is set to 110 the MPC9229 is placed in PLL bypass mode. In this mode the S_CLOCK input is fed directly into the M and N dividers. The N divider drives the F M counter drives the TEST output pin ...

... The key parameter that needs to be met in the final filter design is the DC voltage drop that will be seen between the VCC supply and the MPC9229 pin of the MPC9229. From the data sheet, the VCC_PLL current (the current sourced through the VCC_PLL pin) is maximum 20 mA, assuming that a minimum of 2.835 V must be maintained on the VCC_PLL pin. The resistor shown in Figure 5 must have a resistance of 10-15 Ω ...

... As the oscillator is somewhat sensitive to loading on its inputs the user is advised to mount the crystal as close to the MPC9229 as possible to avoid any board level parasitics. To facilitate co--location TIMING SOLUTIONS surface mount crystals are recommended, but not required. ...
