Clocking

System PLL Configuration

The system PLL is controlled by the RCWL[SPMF] parameter. Table 58 shows the multiplication factor

encodings for the system PLL.

As described in Section 22, “Clocking,” the LBCM, DDRCM, and SPMF parameters in the reset

configuration word low and the CFG_CLKIN_DIV configuration input signal select the ratio between the

primary clock input (CLKIN or PCI_CLK) and the internal coherent system bus clock (csb_clk). Table 59

shows the expected frequency values for the CSB frequency for select csb_clk to CLKIN/PCI_SYNC_IN

ratios.
