(4) t_RJIT specification is the rms jitter measurement of the serializer output when the device is transmitting SYNC pattern.
(5) t_DJIT specification is measured with the serializer output transmitting PRBS pattern from the internal BIST mode. It is a measurement of
the center distribution of 0V (differential) crossing in comparsion with the ideal bit position. See Figure 9
