#define BOARD_FCLKIN_FREQUENCY 16000000 /* 16 MHz crystal frequency */
|

/* The maximum frequency for the TMS570LS0432PZ is 80 MHz.

|
|
* REFCLKDIV controls input clock divider:
|
|
*
|
|
* NR = REFCLKDIV+1
|
|
* Fintclk = Fclkin / NR
|
|
*
|
|
* PLLMUL controls multipler on divided input clock (Fintclk):
|
|
*
|
|
* Non-modulated:
|
|
* NF = (PLLMUL + 256) / 256
|
|
* Modulated:
|
|
* NF = (PLLMUL + MULMOD + 256) / 256
|
|
*
|
|
* Foutputclk = Fintclk x NF (150MHz - 550MHz)
|
|
*
|
|
* ODPLL controls internal PLL output divider:
|
|
*
|
|
* OD = ODPLL+1
|
|
* Fpostodclk = Foutputclock / OD
|
|
*
|
|
* Final divisor, R, controls PLL output:
|
|
*
|
|
* R = PLLDIV + 1
|
|
* Fpllclock = Fpostodclk / R
|
|
*
|
|
* Or:
|
|
*
|
|
* Fpllclock = = (Fclkin / NR) x NF / OD / R
|
|
*
|
|
* In this case, we have:
|
|
*
|
|
* Fclkin = 16,000,000
|
|
* NR = 6 (REFCLKDIV=5)
|
|
* NF = 120 (PLLMUL = 119 * 256)
|
|
* OD = 1 (ODPLL = 0)
|
|
* R = 2 (PLLDIV=1)
|
|
*
|
|
* Then:
|
|
*
|
|
* Fintclk = 16 MHz / 6 = 2.667 MHz
|
|
* Foutputclock = 2.667 MHz * 120 = 320 MHz
|
|
* Fpostodclock = 320 MHz / 2 = 160 MHz
|
|
* Fpllclock = 160 MHz / 2 = 80 MHz
