Well, you can't get exact frequencies from 14.318, but you can get approximations. For example, 14.318*7/3 = 33.408 and 14.318*10/3 = 47.727.
You can get closer with larger fractions. 14.31818 * 352 / 105 = 47.99999390476, which is 6.095238 Hz off of 48 MHz with an error of 6/48 = 0.125 ppm. That's far better than what the crystal will be. Now, I'm not sure exactly how that ratio would be implemented in the PLL. I can think of 4 possibilities offhand: VCO of 48 MHz, VCO divided by 352 and reference divided by 105 for 136.363 kHz. VCO of 240 MHz, VCO divided by 5 for output and 352 for loop, reference divided by 21 for 681.818 kHz. VCO of 720 MHz, divided by 15 for output and 352 for loop, reference divided by 7 for 2.045454 MHz. Or VCO of 1008 MHz, divided by 21 for output and 352 for loop, reference divided by 5 for 2.863636 MHz.
The other outputs would be something similar.
Edit: Here is a page for approximating fractions: http://www.mindspring.com/~alanh/fracs.html . If you put in 3.352381378080175 (48/1.31818), it will generate a list of approximations of increasing accuracy. And 352/105 is probably the most reasonable one, as the terms are relatively small and the result is quite accurate. Now, doing a two-stage PLL is also possible, but not quite as straightforward as the intermediate frequency has to be selected somehow.
