Test Method
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68. Control drive
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Apply 5-V external voltage to pins 1 and 80.
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 18.
Change OSD contrast data to (11), (10), (01), and (00). Measure pin 12 picture period
amplitude V_uOSDR (11), (10), (01), and (00) respectively.
Repeat the steps 3 and 4 above with the following pins: Input from pin 19, and measure pin
13, V_uOSDG (11), (10), (01), and (00). Input from pin 21, and measure pin 14, VuOSDB
(11), (10), (01), and (00).
