I run through datasheet several times. This line best explains how to calculate FCCO
FCCO = (2 × M × FIN) / N
The PLL inputs and settings must meet the following:
• FIN is in the range of 32 kHz to 50 MHz.
• FCCO is in the range of 275 MHz to 550 MHz.
maybe this image will help You (or me :-|...
In this chip first goes input divider (in my case 50) than multiplier (341) after which we have Fcco frequency between 275MHz and 550MHz, and then we have Core divider (10) that lovers Core frequency to 32.736MHz (this one should be less than 70MHz what is satisfied). I was in hunt on all other...
Devider value is 50 and multipler 341, that gives Fcco = (2*341*24MHz)/50 = 327.36MHz. Then i use CORE_CLOCK devider value 10 to get CORE_CLK at 32.736MHz. This should work without any problems, but it wont. I have noticed that when i use small values for M and N i get precise clock as expected.
Hi everyone,
i'm facing a problem with clock generation. My project requires from me to generate clock of 16.368MHz without using this specific crystal oscillator (or ceramic resonator). I found a way to accomplish this using LPC2361 and combination of PLL and PWM settings and 24MHz crystal...
I have to write seminar thesis on topic "Analysis of macrocellular power consumption".
The problem is that i can't find any appropriate literature or any source of knowledge.
Anything connected to this theme would help me.
I found some white papers and presentations

Hi everyone,
I'm trying to find literature for this topic. I found few seminar presentations but nothing serious.
Any help on this would be appreciated ! I really need help :-?
