Single ended 50 Ohm to balanced differential for AD9548

Hello everyone.
Just received my AD9548 Eval Board, and I want to test the PLL Quick Start as explained in page 7 of the Eval Manual (UG-639).


I see that there is a necessity to feed RefA with differential balanced input, while my source is single ended (50 Ohm). What do you suggest for this case? Do I need a BalUn? How to get the correct impedance levels?


Thanks for all.
