5.3
All clocks used on the MPC8572EAMC are generated locally using crystal oscillators. The only exception
is the PCI-Express clock, which can be generated either locally (using a 100-MHz crystal oscillator), or
externally using the FCLKA input pins (pins 80 and 81 on the AdvancedMC connector). This clock
selection is controlled via the System CPLD logic. A number of different clocking schemes are used on
the MPC8572EAMC, as follows:
5.3.1
The system clock is provided by a 66.66-MHz crystal oscillator. This clock is fed through a 22 Ω series
resistor to produce the required processor system clock, as shown in
