Re: Newbie with LPC2106 - Please help

2004-08-26 by acetoel

Just a simple question about the cristal. I know that this MCU (as 
some PICs) has internal PLL. The question is, which is te range of 
External Cristal OSC, and then between what ranges I have to set the 
Internal PLL. I read somewhere, don't remember where, that the 
external cristal should be between 1MHz and 25Mhz, and in the PLL 
Calculator program, there's a maximun of 60Mhz for the clock.
Which is the more recomendable selection, and which one gives more 
performance (higher Bus Clock, Higher MCU clock...and so on).
Thanks for the patience...
Ezequiel
