The LPC1768 manual mentions that “PLL0 parameter determination can be simplified by using a spreadsheet available from NXP”.
Anyone know where to find this spreadsheet? I’ve searched the NXP website without success.
It’s in the LPC2000 group files section.
Ah, no wonder I couldn't find it anywhere in the LPC1700 section. :-(leon_heller:

It can also be downloaded from the NXP website:
http://ics.nxp.com/support/documents/mi … ulator.xls
(the last part is: …/documents/microcontrollers/xls/lpc17xx.pll.calculator.xls)
That would be more suitable for the LPC1768. The other one wasn’t written by NXP, and isn’t as comprehensive.
