MPC8572EAMC Functional Description
5.3.7
MPC8572EAMC SERDES LVDS Clock (100/125MHZ)
The MPC8572E microprocessor has integrated support for both PCI-Express and Serial RapidIO. To
support both PCI-E and SRIO standards, two high precision crystal oscillators are used, 100 MHz and
125 MHz. The AdvancedMC standard also requires that common clocking is supported via the fabric
clock interface, FCLKA. Figure 5-16 illustrates how the ICS854054 fan-out buffer connects to the three
differential clock input sources.
Figure 5-16. SERDES 100/125MHZ/FCLKA Clock Configuration
Table 5-14 shows the truth table for the ICS854054 device. The selected differential LVDS clock output
is then fed into an ICS85411, 1-to-2 Differential-to-LVDS fan-out buffer. This buffer splits the LVDS input
clock out to the two SERDES interfaces on the MPC8572E. This logic is automatically handled by the
System CPLD logic.

MPC8572EAMC Clock Port Region
The AdvancedMC clock port region is located on pins 74 through 82 on the AdvancedMC edge connector.
Differential synchronization clock 1 on pins 74/75, differential synchronization clock 2 on pins 77/78 and
differential synchronization clock 1 on pins 80/81. The AdvancedMC specification dictates that two types
of optional clock sources are provided to/from the board: four Telecom clocks and one Fabric clock. The
