To simplify the PLL configurations, the MPC8309 might be separated into two clock domains. The first
domain contains the CSB PLL and the core PLL. The core PLL is connected serially to the CSB PLL, and
has the csb_clk as its input clock. The second clock domain has the QUICC Engine PLL. The clock
domains are independent, and each of their PLLs is configured separately.
The following table shows suggested PLL configurations for 33 and 66 MHz input clocks.

The VCO divider (RCWL[CEVCOD]) must be set properly so that the
QUICC Engine VCO frequency is in the range of 300–600 MHz. The
QUICC Engine frequency is not restricted by the CSB and core frequencies.
The CSB, core, and QUICC Engine frequencies should be selected
according to the performance requirements.
The QUICC Engine VCO frequency is derived from the following
equations:
qe_clk = (primary clock input × CEPMF)  (1 + CEPDF)
QUICC Engine VCO Frequency = qe_clk × VCO divider × (1 + CEPDF)
