Input signal 1(f
gain adjustment data so that pins 41 and 42 picture period amplitude equals that of pin 43.
Apply 5-V external voltage to pin 49.
Input signal 1(f
Measure pin 43 picture period amplitude, vTXACL1.
Apply “pin 53 DC voltage − 0.8 V” to pin 53 from external power supply, and measure pin
43-picture period amplitude, vTXACL2.
Apply “pin 53 DC voltage − 1.3 V” to pin 53 from external power supply, and measure pin
43-picture period amplitude, vTXACL3.
