Hi
I am currently working on a ultra-low noise/jitter clock source and am using TI's LMK04828 for frequency upconversion. I would like to add an external ref in- and output (10Mhz standard) for chaining and locking multiple other devices. I was planning on using a high speed buffer (ADCLK905) to protect and boost the input stage. Now I am wondering whether it is good practice or advisable to also add a transformer (i.e. 1:2 for 50 ohms match) and/or a common mode chocke after the BNC input in front of the buffer? Same question also applies for the output: would you put a trafo or directly provide the reference output?
Thanks for any advice
