PLL settings for the S3C2410

Sort of. What do you want to know?

cheers,

Al

My questions are regarding the formula they provide on page 7-19 of the User Manual, and the table for the recommended settings on 7-20, together with the note on 7-19 stating that one should ask them if setting values for the formula that are not listed in the table.

In my particular example I try to set a frequency of 250 MHz from an input one of 12 MHz. From the formula I could use following settings several different settings, for example:

a) m=159, p=2, s=1 for 250.50 MHz b) m=117, p=1, s=1 for 250 MHz

and a lot of other ones that the PLLSET.exe utility you can download from the website reports... Which are the best ones to use? why?

best thanks,
