21.1

System PLL Configuration

The system PLL is controlled by the RCWL[SPMF] and RCWL[SVCOD] parameters. This table shows the multiplication

factor encodings for the system PLL.

Notes:

1. The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen such that the resulting csb_clk,

MCLK, LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies.

2. The 667 MHz core frequency is based on a 1.3 V VDD supply voltage.

3. The 500 MHz QE frequency is based on a 1.3 V VDD supply voltage.

4. The DDR data rate is 2x the DDR memory bus frequency.

5. 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]).
