Input signal 1(f
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Apply 5-V external voltage to pin 2.
Input signal 1(f
Measure pin 12 picture period amplitude, v12R.
Repeat the steps 3 and 4 above with the following pins:
Input from pin 25, and measure output from pin 13 (v13G).
Input from pin 26, and measure output from pin 14 (v14B).
Calculate the following equations. GTXR = v12R/0.2 GTXG = v13G/0.2 GTXB = v14B/0.2
Input signal 1(f
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Apply 5-V external voltage to pin 2.
Set RGB contrast data to maximum (7F).
Input signal 2 to pin 24. Gradually increase picture amplitude, and measure picture period
amplitude voltage when output from pin 12 is clipped.
Repeat the steps 3 and 4 above with following pins: Input from pin 25 and measure output
from pin 13. Input from pin 26 and measure output pin 14.
