A
(1) Connect power supply to pin 21 (Digital Ys) and impress 1.5 V to it.
(2) Connect power supply to pin 19 (Digital G IN). While raising supply
voltage gradually from 0 V, measure supply voltage when output
signal of pin 13 (G OUT) changes (Vtxt).
(3) Raising the supply voltage to pin 19 furthermore to 4 V, confirm
that there is no change in the output signal of pin 13 (G OUT).

OSD Input Threshold
Level
(1) Connect power supply to pin 21 (Digital Ys) and impress 2.5 V to it.
(2) Connect power supply to pin 19 (Digital G IN). While raising supply
voltage gradually from 0 V, measure supply voltage when output
signal of pin 13 (G OUT) changes (Vosd).
(3) Raising the supply voltage to pin 19 furthermore to 4 V, confirm
that there is no change in the output signal of pin 13 (G OUT).
