Clocking
Note that there is no default for this PLL ratio; these signals must be pulled to the desired values. Also note
that the DDR data rate is the determining factor in selecting the CCB bus frequency, since the CCB
frequency must equal the DDR data rate.
19.3
e500 Core PLL Ratio
Table 66 describes the clock ratio between the e500 core complex bus (CCB) and the e500 core clock. This
ratio is determined by the binary value of LBCTL, LALE, and LGPL2 at power up, as shown in Table 66.
19.4
PCI Clocks
For specifications on the PCI_CLK, refer to the PCI 2.2 Local Bus Specifications.
The use of PCI_CLK is optional if SYSCLK is in the range of 33–66 MHz. If SYSCLK is outside this
range then use of PCI_CLK is required as a separate PCI clock source, asynchronous with respect to
SYSCLK.
