Note 8: Specification is guaranteed by characterization.
Note 9: A Clock Unit Symbol (T) is defined as 1/ (Line rate of RCLK). E.g. For Line rate of RCLK at 85MHz, 1 T = 11.76ns
Note 10: A Unit Interval (UI) is defined as 1/7th of an ideal clock period (RCLK/7). E.g. For an 11.76ns clock period (85MHz), 1 UI = 1.68ns
