(1) Input TG7 sine wave signal (f = 4 MHz, video amplitude = 0.5 V) to
pin 31 (Y2 IN).
(2) Short circuit pin 25 (Analog G IN) in AC coupling.
(3) Input 0.3 V synchronizing signal to pin 48 (Sync IN).
(4) Set bus data so that contrast is maximum, Y sub contrast and drive
are set at center value.
(5) Supply pin 22 (Analog Ys) with 0 V of external power supply.
(6) Measure video voltage of output signal of pin 13 (G OUT) (Vtg).
(7) Supply pin 22 (Analog Ys) with 2 V of external power supply.
(8) Measure video voltage of output signal of pin 13 (G OUT) (Vana).
(9) From measurement results of the above steps 5 and 7, calculate
crosstalk from TV to analog RGB.
Crtva = 20 og (Vana / Vtv)
