Clocking
This table provides the operating frequencies for the TEPBGA II under recommended operating
conditions (see Table 2).
24.1
System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 73 shows the multiplication factor
encodings for the system PLL.
NOTE
If RCWL[DDRCM] and RCWL[LBCM] are both cleared, the system PLL
VCO frequency = (CSB frequency)
(System PLL VCO Divider).
If either RCWL[DDRCM] or RCWL[LBCM] are set, the 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.

Note:
1. The SYS_CLK_IN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting csb_clk,
MCK, LCLK[0:1], 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 lbiu_clk frequency (depending on LCRR[CLKDIV]) which is in turn 1x or 2x the
csb_clk frequency (depending on RCWL[LBCM]).
