I have a 50ohm clocking system in a very low noise environment(RADAR). I want to use a Abracon 100MHz VCXO (this one), which has a 3,3V LVCMOS output. Below you can see the block diagram of the implementation. enter image description here

Previously I measured the output of the mentioned Abracon VCXO that if I terminate the output with 50ohm it produces 10dBm signal.

My question: Despite the fact that the LVCMOS output crystal can drive the 50ohm system, are there any downsides of this implementation? (e.g.: worse aging, degradation of phase noise over the years etc..)
