LO for AD8333

In my project I need to demodulate a signal with carrier frequency of 250kHz. Since AD8333 has a divided-by-4 LO input, I need a local oscillator of 1MHz.

I would like to know if the Si545 component (crystal oscillator with 1MHz) could be used in this case.

And since the output of Si545 is LVDS, can I just connect Si545 and 4LO input of AD8333 by DC-coupling?
