Acceptable designing two clock generators using single package?
For such extremely unrelated frequencies to be derived from the same clock, your only choices would be


a fractional-N synthesizer, or 
a digital synthesis with either a very large table or an ad-hoc
cosine computation (typically based on a CORDIC). 


You can implement the former using standard RF clock synthesizers (LMX2571, MAX2870,…) ; many of them will be specialized for RF generation, so you might need to divide the results down afterwards.

Digitally, I don't know whether there's ready-to-use digital direct synthesis (DDS) chips that have an internal table large enough to allow for sufficient frequency resolution. If you can't find one suitable, a possible way would be implementing a large DDS yourself, e.g. with a medium sized FPGA and enough memory for a sufficiently large table plus a DAC. Alternatively, just calculate \$\cos(2\pi f t)\$ for arbitrary \$f\$ yourself on an FPGA with a couple of multipliers – the CORDIC algorithm family is your friend.
