89 / 102 page  MPC8360E/MPC8358E PowerQUICC II Pro Processor Revision 2.x TBGA Silicon Hardware Specifications, Rev. 5 Freescale Semiconductor 89 Suggested PLL Configurations The QUICC Engine block VCO frequency is derived from the following equations: ce_clk = (primary clock input × CEPMF) ÷ (1 + CEPDF) QE VCO Frequency = ce_clk × VCO divider × (1 + CEPDF) 21.4 Suggested PLL Configurations To simplify the PLL configurations, the device 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 block PLL. The clock domains are independent, and each of their PLLs are configured separately. Both of the domains has one common input clock. This table shows suggested PLL configurations for 33 and 66 MHz input clocks and illustrates each of the clock domains separately. Any combination of clock domains setting with same input clock are valid. Refer to Section 21, “Clocking,” for the appropriate operating frequencies for your device. Table 76.
