Can I clock the SOMOMAPL138-10-1602AHCR DSP at 375MHz?

If so, how?

Thx,

  • Can anyone comment on this?

  • Hi MikeH,

                   According to hardware specification of the borad ( OMAP-L138 SOM-M1 runing using an single external 24.000 MHz crystal.

                   The Maximum Frequency Limit of ( OMAP-L138 SOM-M1 ) is 375MHz.

                   If it is Configured the following way  

                   PLLM(PLL Multiplier) = 14 ;

                   PLLDIV = 1;          

                   POSTDIV = 1;

                   Then the Clocks reaches ((24*(14+RATIO)) /1) = 360MHz.

                   or

                  PLLM(PLL Multiplier) = 30 ;

                   PLLDIV = 2;          

                   POSTDIV = 1;

                  Then the Clocks reaches ((24*(30+RATIO)) /2) = 372 MHz   (Nearly 375 MHz)        [DEFAULT : RATIO =1 ]

                   If the External Crysal of the Board is replaced by 25 MHz the the clocks reaches 375 MHz.
