TEST CONDITION (V_CC = 9V, Ta = 25±3°C)
MEASUREMENT METHOD
(1) Apply the IF signal. (f₀ = 45.75MHz, 87.5% AM,
31.6mV_rms) to IF input.
(2) Measure the output signal level at pin 47. (V₀₁)
(3) Apply the signal (100% AM, 31.6mV_rms) to IF input.
(4) Measure the output signal level pin 47. (V₀₂)
(1) Apply the signal (f₀ = 45.75MHz, 30% AM, 31.6mV_rms)
to IF input.
(2) Decrease input signal level. Measure the input signal level at IF input, when
output signal level at pin 47 decreases as −3dB level. (V_{IN MIN})
(3) Increase input signal level. Measure the input signal level at IF input, when
output signal level at pin 47 increases as +0.5dB level. (V_{IN MAX})
(1) Apply the signal (f₀ = 45.75MHz, 31.6mV_rms, Non modulation) to IF input.
(2) Measure the DC voltage at pin 47 (V_SYNC)
(1) Non IF input
(2) Apply 3.0V at pin 5.
(3) Measure the DC voltage at pin 47. (V_IF)
(1) Apply the IF signal (f₀ = 45.75MHz, 87.5% AM Video) to IF input.
(2) Measure the differencial gain and phase at pin 47.
