[time-nuts] Best way for generating 8994.03 MHz from 2899.00042272.....MHz?

Corrected version:

Yes.  The ideal architecture would be to use a dielectric resonator
oscillator at 8994 MHz as the output source.  Then divide its output by
two.  Take that ~4.5 GHz signal and divide it by 757 using the divide by N
section of an Analog Devices ADF4106.  Divide the 2899 MHz by
488 using the divide by N section of a second ADF4106.  488 is 2/3 of
732.

Feed the "muxout" of the second ADF4106 into the "ref in" of the first
ADF4108 and use the phase detector in the first ADF4106 to tune the DRO.
(This will become clear after you read the ADF4106 data sheet :-)  The
phase detector frequency will be about 6 MHz.
