(1) Input TG7 sine wave signal (f = 4MHz, video amplitude = 0.5V) to
pin 31 (Y2 IN).
(2) Short circuit pin 25 (Analog G IN) in AC coupling.
(3) Input 0.3V synchronizing signal to pin 51 (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 0V of external power supply.
(6) Measure video voltage of output signal of pin 13 (G OUT) (Vtg).
(7) Supply pin 22 (Analog Ys) with 2V 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 = 20og (Vana / Vtv)

(1) Short circuit pin 31 (Y2 IN), pin 34 (R-Y IN) and pin33 (B-Y IN) in
AC coupling.
(2) Input 0.3V synchronizing signal to pin 51 (Sync IN).
(3) Set bus data so that contrast is maximum and drive is set at center
value.
(4) Input TG7 sine wave signal (f = 4MHz, video amplitude = 0.5V) to
pin 24 (Analog G IN).
(5) Supply pin 22 (Analog Ys) with 0V of external power supply.
(6) Measure video voltage of output signal of pin 13 (G OUT) (Vant).
(7) Supply pin 22 (Analog Ys) with 2V of external power supply.
(8) Measure video voltage of output signal of pin 13 (G OUT) (Vtan).
(9) From measurement results of the above steps 6 and 8, calculate
crosstalk from analog RGB to TV.
Crant = 20og (Vant / Vtan)
