Hi all
I need to increase the frequency of my PIC18F4620 to MAXIMUM possible. Im using it on a PICDEM2 PLUS board and has no external clock source- suggesting I would need to buy one.
Currently Im using internal oscillator with PLL [ Fosc= 32 Mhz ( 8Mhz, internal clock)]. I need to increase this 8Mhz to 40 Mhz...Is it possible using an external oscillator?
Maybe HS mode with PLL ?
Does this mean I need a crystal with 10Mhz MAX ?

Code:
The HSPLL mode makes use of the HS mode oscillator
for frequencies up to 10 MHz. A PLL then multiplies the
oscillator output frequency by 4 to produce an internal
clock frequency up to 40 MHz.
