Clocking
19.1
System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 60 shows the multiplication factor
encodings for the system PLL.
As described in Section 19, “Clocking,” the LBIUCM, 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 61
3 The DDR data rate is 2× the DDR memory bus frequency.
4 The local bus frequency is , , or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1× or 2× the
csb_clk frequency (depending on RCWL[LBIUCM]).
