rf mixer for 74hct4046 pll question

I am interested in building a simple fm reciever using a 74hct4046 pll as a demodulator. The reciever must have a range between 902 and 905 MHz. I guess my question is do I need to mix the input signal down before demodulation? If so, what would be a good frequency to mix down to?
It's also my understanding that this pll can be an fm demodulator and a mixer, but not both, is this correct?
Any thoughts on mixing circuits would be great too.

thanks.

You need to study superheterodyne receivers. To get from 900Mhz to a frequency that a 4046 can demodulate (<1Mhz), you will need at least two and maybe three intermediate frequencies and mixers.

This is definitely going to take some more research. Thanks for the response.

It's not the kind of PLL intended for RF use - I would suggest you look at other suitable PLL's.
