generating MHz frequencies

[amereshadow]

hi there, after my previous problem, solved after a few days (now ducati is happy and my laurea thesis too) i have another question

i was testing a circuit received by a friend of mine, an RF circuit which used an inverting Schmitt trigger (74hc14) 2 xtal and some passives to generate two square wave @ 2~3MHz; then the frequency is divided by two using a counter and taking the least significant bit. at this point i have two frequencies at a bout 1,2288 and 1.5 MHz.
because i didn't have some components (56pf cap and 2.4576MHz xtal) i trying to generate the two freq (1.5 and 1.2) with a pic, or two pic. i can dedicate an entire pic to a single frequency generation, but how? PWM or software? with a 877a at 10MHz theoretically i could generate both the frequencies, or no?

tnx
pietro

You will only be able to generate such a high frequency with the PIC if the clock oscillator for that PIC is an exact multiple of the frequency you want to generate. Then PWM will give you the highest frequency.
