System Design Information
20 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8640.
20.1
System Clocking
This device includes six PLLs, as follows:
The platform PLL generates the platform clock from the externally supplied SYSCLK input. The
frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio
configuration bits as described in Section 18.2, “MPX to SYSCLK PLL Ratio.
The dual e600 Core PLLs generate the e600 clock from the externally supplied input.
The local bus PLL generates the clock for the local bus.
There are two internal PLLs for the SerDes block.
20.2
Power Supply Design and Sequencing
This section describes the power supply design and sequencing.
20.2.1
PLL Power Supply Filtering
Each of the PLLs listed in Section 20.1, “System Clocking,is provided with power through independent
power supply pins.
There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to
provide independent filter circuits per PLL power supply as illustrated in Figure 64, one to each of the
AVDD type pins. By providing independent filters to each PLL the opportunity to cause noise injection
from one PLL to the other is reduced.
This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz
range. It should be built with surface mount capacitors with minimum Effective Series Inductance (ESL).
Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook
of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a
single large value capacitor.
Each circuit should be placed as close as possible to the specific AVDD type pin being supplied to minimize
noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD
type pin, which is on the periphery of the footprint, without the inductance of vias.
Figure 63 and Figure 64 show the PLL power supply filter circuits for the platform and cores, respectively.
