I also happen to have some spare B200 devices around and I can confirm what @Martin stated.
Since we are working in a jitter-sensitive critical application and after the tests I've perfomed, I'm inclined to think the minimum jitter scenario occurs when using the internal reference (2 ppm), given that even using a high precision laboratory equipment (Agilent) as an external clock source shows worse results than the former (as it can be seen in the images from my first post). Shall we work with the internal reference then or am I missing something on what you said? Regards, Brais.
