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.
2. Apply 5-V external voltage to pin 2.
3. Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 24.
4. Measure pin 12 picture period amplitude, vTXACL1.
5. Apply “pin 78 DC voltage − 0.8 V” to pin 78 from external power supply, and measure pin
12-picture period amplitude, vTXACL2.
6. Apply “pin 78 DC voltage − 1.3 V” to pin 78 from external power supply, and measure pin
12-picture period amplitude, vTXACL3.
7. TXACL₁ = −20 × log (vTXACL2/vTXACL1)
TXACL₂ = −20 × log (vTXACL3/vTXACL1)
