Lpc2000

Hello Slawc,

first many thanks for your answer !

Ok, i found the separate PLL in the overview diagram on page 3 of the 
preliminary data sheet from 22 June 2005. But this doesn't mean that i reach 
a USB suitable frequency (i think something like 12 MHz) from my odd 
frequency 14,745 MHz, even if i have a separate PLL ?

Where (on which page) have you found the 18 Ohm resistors ?

Ok, the 29 to 44 Ohm are in table 10 page 31. But then also the 33 Ohm 
values could be correct, because total is 33 Ohm which is in this 
interval...
