System Design Information
Freescale Semiconductor
76
The filter for System/Core PLLVDD to VSS should be connected to the power and ground planes, respectively, not fingers of
the planes.
In addition to keeping the filter components for System/Core PLLVDD as close as practical to the body of the MPC5121e as
previously mentioned, special care should be taken to avoid coupling switching power supply noise or digital switching noise
onto the portion of that supply between the filter and the MPC5121e.
The capacitors for C2 in the figure below should be rated X5R or better due to temperature performance.

Connection Recommendations
To ensure reliable operation, connect unused inputs to an appropriate signal level. Unused active low inputs should be tied to
VDD_IO. Unused active high inputs should be connected to VSS. All NC (no-connect) signals must remain unconnected.
Power and ground connections must be made to all external VDD and VSS pins of the MPC5121e/MPC5123.
The unused AVDD_FUSEWR power should be connecetd to VSS directly or via a resistor.
For DDR or LPDDR modes the unused pins VTT[3:0] for DDR2 Termination voltage can be unconnected.
The SATA PHY needs to be powered even if it is not used in an application. In this case, you should not enable the SATA
oscillator and the SATA PHY by software.
