VGA to PAL converter ?

Hi, I use a vga ouput to display video from a camera (see attached picture). I would like to add PAL output. I wonder if a single chip which converts vga (analog, digitial ?) to pal exists ? ...

I think the AD725 could do what I want.

I am not familiar with PAL video : does the clock (4fsc) could be generated with a cyclone II ?

the datasheet specifies 17.734 475MHz and it is quit hard to obtain from a cyclone II...

is it possible to generate 4fsc with a cyclone II ? if not which oscillator can be used ?

thanks.
