(5) Force +/- 100 uA on output, measure delta V on the Output and calculate impedance. Mismatch is the percentage difference of OUTn+
and OUTn- impedance driving the same logic state.
(6) Default VOD used for testing. DE = -1.5 dB level used to compensate for fixture attenuation.
(7) Typical jitter reported is determined by jitter decomposition software on the DSA8200 Oscilloscope.
