[size=18]Hello Everybody.
I can generate a 2.048 MHz clock, with the PIC 16F630. (I need square signal, Duty cycle=0.5)
has anybody experimented this?
Thanks in advance. [/size]

In one sense, forget it.
Chose a chip with a hardware PWM module instead, and select a crystal frequency that is a nice multiple of the required frequency. One way you could do this on the 63, would be to use a 2.048MHz crystal, and run the processor on this. However the duty cycle may not then be perfect.

Ok. I already imagined that should change my project. I believe that will implement a clock generator. Thank you for its help.
Congratulations.
