30R Q01_1 = MMBF4392 Q01_2 = MMBTH10LT1 R01_27/29 = 250R RX1_1..4 = 280R RA01_1/2 = 22R U01_3 = LMH6552 I did some measurements and simulations, and after some experimenting I came to the following set of modifications. In some cases they contradict tinhead’s approach in http://www.mikrocontroller.net

from 1 to 2, so RX1_3=RX1_4=390R, and RX1_1=RX1_2=180R. Should be 0.1% tolerated parts according to LMH6552 datasheet. 9. RA01_1/2 On its way from the LMH6552 to the ADCs, the signal runs through differential transmission lines. But as they are not terminated at the receivers, we can expect reflections
