Test Conditions
V1. Circuit current [15]
1. Internal AGC
2. Input a 45.75MHz, 10mVrms, CW signal to the VIF input pin.
3. RF AGC Vr maximum
4. Connect a current meter to VCC and measure the current flowing into the IC.
V2, V3. Maximum RF AGC voltage, minimum RF AGC voltage [V9H, V9L]
1. Internal AGC
2. Input a 45.75MHz, 10mVrms, CW signal to the VIF input pin.
3. Vary the RF AGC Vr and, at the maximum resistance, measure the maximum RF AGC voltage. (F)
4. Vary the RF AGC Vr and, at the minimum resistance, measure the maximum RF AGC voltage. (F)
V4. Input sensitivity [Vi]
1. Internal AGC
2. fp = 45.75MHz, 400Hz 40% AM (VIF input)
3. Set S1 to the off position and pass the input through a 100k
resistor.
4. Measure the VIF input level such that the 400Hz detection output level at test point A becomes 0.64Vp-p.
V5. AGC range [GR]
1. External AGC. Apply the VCC voltage to the IF AGC input (pin 17).
2. With the same conditions as used for V4, measure the VIF input level such that the detection output level becomes
0.64Vp-p. Vi1
3. GR = 20log
Vi1
Vi
dB
V6. Maximum allowable input [Vi max]
1. Internal AGC
2. fp = 45.75MHz, 15kHz 78% AM (VIF input)
3. Measure the VIF input level such that the detection output level at test point A is
±1dB of the video output (Vo).
V7. Video output voltage (no input) [V6]
1. External AGC. Apply the VCC voltage to the IF AGC input (pin 17).
2. Measure the video output (A) DC voltage.
V8. Sync signal tip voltage [V6tip]
1. Internal AGC
2. Input a 45.75MHz, 10mVrms, CW signal to the VIF input pin.
3. Measure the video output (A) DC voltage.
V9. Video output level [VO]
1. Internal AGC
2. fp = 45.75MHz, 15kHz 78% AM
Vi = 10mVrms (VIF input)
3. Measure the wave height of the detection output level at test point A. (Vp-p)
