Hi

9.3804 MHz = (2^15*3) * 100 Hz

10 MHz = 2^5 * 5^5 * 100 Hz

With a normal integer PLL, your highest lock frequency would be 2^5* 100 Hz = 
3200 Hz.

Doable, but you better care about details, and going for a PI-loop is the way to go. For lower ratios between locked frequency and comparator frequency you can cheat more if you do not have any particular requirements.
