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, vTXACL1.
Apply “pin 78 DC voltage − 0.8 V” to pin 78 from external power supply, and measure pin
12-picture period amplitude, vTXACL2.
Apply “pin 78 DC voltage − 1.3 V” to pin 78 from external power supply, and measure pin
12-picture period amplitude, vTXACL3.
