Test Method
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68.
Measure pins 14, 13, and 12 picture period amplitude, v14a, v13a, and v12a.
Apply 5-V external voltage to pin 80.
Measure pins 14, 13, and 12 picture period amplitude, v14b, v13b, and v12b.
5. Calculate v14b amplitude in relation to v14a, v13b amplitude in relation to v13a, and v12b
amplitude in relation to v12a in decibel: α14TV1, α13TV1, and α12TV1.
6. Apply 5-V external voltage to pin 1, and repeat the steps 3 to 5 above: α14TV2, α13TV2, and
α12TV2.
7. Apply 5-V external voltage to pins 1 and 80, and repeat the steps 3 to 5 above: α14TV3,
α13TV3, and α12TV3.
8. Set SW68 to C. Set SW21, 19, and 18 to B.
9. Input signal 1 (f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pins 21, 19, and 18.
10. Apply 5-V external voltage to pins 1 and 80.
11. Measure pins 14, 13, and 12 picture period amplitude, v14c, v13c, and v12c.
12. Apply 5-V external voltage to pin 1.
13. Measure pins 14, 13, and 12 picture period amplitude, v14d, v13d, and v12d.
14. Calculate v14d amplitude in relation to v14c, v13d amplitude in relation to v13c, and v12d
amplitude in relation to v12c in decibel: α14OSD1, α13OSD1, and α12OSD1.
15. Apply 5-V external voltage to pin 80, and repeat the steps 12 to 14 above: α14OSD2,
α13OSD2, and α12OSD2.
16. Apply 5-V external voltage to pins 1 and 80, and repeat the steps 12 to 14 above: α14OSD3,
α13OSD3, and α12OSD3.
