pic programming for serial communication

[waqassalam]

hi guys .......
i am new in pic family....>>>
my first question is that ,can i input sine wave of frequency around 450khz which i have to sample by using internal ADC of pic 16f877 or 16f887..
if yes then further i have to send these 10 bit to MATLAB through serial communication where i have to perform FFT on these bits ..
plzz send me the coding to perform this task ...

This isn't possible with the PIC16F877/887 internal AD converter (have only 20000 samples per second). You will need one external fast AD converter, depending on how many points you want to read the sinusoid.

IN ADC register ADCon1 have different clock rate period mode for example::
Fosc/8 or fosc/4 or fosc/32, these three selesting modes are.if we choose 8MHZ oscillator
and by chosing fosc/8 it will give 500khz.or 2 microsecond clock rate period...
if i increase oscilattor frequency then i cant achieve more than 500khz sampling rate...
