System PLL Configuration
The RCWL[SVCOD] denotes the system PLL VCO internal frequency as shown in this table.
NOTE
The VCO divider must be set properly so that the system VCO frequency is in the range of
600–1400 MHz.
The system VCO frequency is derived from the following equations:
csb_clk = {PCI_SYNC_IN × (1 + CFG_CLKIN_DIV)} × SPMF
System VCO Frequency = csb_clk × VCO divider (if both RCWL[DDRCM] and RCWL[LBCM] are cleared)
OR
System VCO frequency = 2
× csb_clk × VCO divider (if either RCWL[DDRCM] or RCWL[LBCM] are set).
As described in Section 21, “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). This table shows the expected frequency values for the CSB frequency for
select csb_clk to CLKIN/PCI_SYNC_IN ratios.
