(1) Measured to AGND.
(2) Measured to VSSCLK.
(3) Measured to DGND.
(4) SYSREF+/- termination has two options. In option 1 the inputs are weakly self-biased to the optimal common mode voltage, which is appropriate for AC coupling. In option 2, each input terminal is connected through 50Ohms to ground, which is appropriate to level shift from a higher common mode voltage.
