System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 58 shows the multiplication factor
encodings for the system PLL.
NOTE
System PLL VCO frequency = 2 × (CSB frequency) × (System PLL VCO
divider). The VCO divider needs to be set properly so that the System PLL
VCO frequency is in the range of 450–750 MHz.
As described in Section 23, “Clocking,” the LBCM, DDRCM, and SPMF parameters in the reset
configuration word low select the ratio between the primary clock input (SYS_CLK_IN) and the internal
coherent system bus clock (csb_clk). The following table shows the expected frequency values for the CSB
frequency for selected csb_clk to SYS_CLK_IN ratios.
DDR2 memory bus frequency (MCLK)2
167
MHz
Local bus frequency (LCLKn)3
66
MHz
Notes:
1. The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting
csb_clk, MCLK, LCLK, and core_clk frequencies do not exceed their respective maximum or minimum operating
frequencies.
2. The DDR2 data rate is 2× the DDR2 memory bus frequency.
3. The local bus frequency is 1/2, 1/4, or 1/8 of the lb_clk frequency (depending on LCRR[CLKDIV]) which is in turn 1× or 2×
the csb_clk frequency (depending on RCWL[LBCM]).
