Signal integrity : L0, clock, Specs

The first two pictures represent the clock signal after 30m of RJ45 cable, terminated on 100 ohms, the two polarities are seen . The differential swing is 440-500 mv with a nominal threshold of 100mv. The third picture is the clock seen before the cable

The next 4 signals represent L0 signals: The driver drives in the 100 ohm cable and a 45/2 ohm load. The signal heigth is a bit marginal but will increase after removing the loads or replacing it by 100 ohms
