Freescale Semiconductor
This table provides the operating frequencies for the TePBGA II package under recommended operating
conditions (see Table 3).
22.1
System PLL Configuration
The system PLL is controlled by the RCWLR[SPMF] parameter. The system PLL VCO frequency
depends on RCWLR[DDRCM] and RCWLR[LBCM]. Table 71 shows the multiplication factor encodings
for the system PLL.
NOTE
If RCWLR[DDRCM] and RCWLR[LBCM] are both cleared, the system
PLL VCO frequency = (CSB frequency)
× (System PLL VCO Divider).
If either RCWLR[DDRCM] or RCWLR[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 400–800 MHz.

Notes:
1. The CLKIN frequency, RCWLR[SPMF], and RCWLR[COREPLL] settings must be chosen such that the resulting
csb_clk,
MCK, LCLK[0:2], and
core_clk frequencies do not exceed their respective maximum or minimum operating frequencies.
The value of SCCR[xCM] must be programmed such that the maximum internal operating frequency of the Security core,
USB modules, SATA, and eSDHC will not exceed their respective value listed in this table.
2. The DDR data rate is 2
× the DDR memory bus frequency.
3. The local bus frequency is , , or 1/8 of the
lbiu_clk frequency (depending on LCRR[CLKDIV]) which is in turn 1× or 2×
the
csb_clk frequency (depending on RCWLR[LBCM]).
