Clocking
Table 55 provides the operating frequencies for the device under recommended operating conditions
21.2
System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 56 shows the multiplication factor
encodings for the system PLL.
As described in Section 21, “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

Notes:
1. The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting
csb_clk,
MCK, LCLK0, and
core_clk frequencies do not exceed their respective maximum or minimum operating frequencies.
2. The DDR data rate is 2x the DDR memory bus frequency.
3. The local bus frequency is 1/2, 1/4, or 1/8 of the
lbc_clk frequency (depending on LCCR[CLKDIV]) which is in turn, 1x or 2x
the
csb_clk frequency (depending on RCWL[LBCM]).
