Notes) 1 Adjust the output amplitude of the inversion and the non-inversion amplifiers in the signal input block to an equal value, as well as the phase difference to a precise 180. Also set the clock and input signal frequency accurately. 2 VIC, VIY, VID and VIT are defined as follows: VIC, VIY, VID and VIT are input signal clamp levels. They clamps the Video signal sync tip level. They are the pin voltages at no-input signal for pins 3, 2, 30 and 5, respectively.
