Test Conditions
V1. Circuit current [I5]
(1) Internal AGC
(2) Input a 45.75MHz 10mVrms continuous wave to the VIF input pin.
(3) RF AGC Vr MAX
(4) Connect an ammeter to the VCC and measure the incoming current.
V2.V3. Maximum RF AGC voltage, Minimum RF AGC voltage [V14H, V14L]
(1) Internal AGC
(2) Input a 45.75MHz 10mVrms continuous wave to the VIF input pin.
(3) Adjust the RF AGC Vr (resistor value max.) and measure the maximum RF AGC voltage. F
(4) Adjust the RF AGC Vr (resistor value min.) and measure the minimum RF AGC voltage. F
V4. Input sensitivity [Vi]
(1) Internal AGC
(2) fp = 45.75MHz 400Hz 40% AM (VIF input)
(3) Turn off the S1 and put 100k
through.
(4) VIF input level at which the 400Hz detection output level at test point A becomes 0.35Vp-p.
V5. AGC range [GR]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 17).
(2) In the same manner as for the V4 (input sensitivity), measure the VIF input level at which the detection output
level becomes 0.35Vp-p. Vil
(3) GR = 20log
dB
V6. Maximum allowable input [Vi max]
(1) Internal AGC
(2) fp = 45.75MHz 15kHz 78% AM (VIF input)
(3) VIF input level at which the detection output level at test point A is video output (VO) ±1dB.
V7. No-signal video output voltage [V6]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 17).
(2) Measure the DC voltage of VIDEO output (A).
V8. Sync. signal tip voltage [V6tip]
(1) Internal AGC
(2) Input a 45.75MHz 10mVrms continuous wave to the VIF input pin.
(3) Measure the DC voltage of VIDEO output (A).
V9. Video output level [VO]
(1) Internal AGC
(2) fp = 45.75MHz 15kHz 78% AM Vi = 10mVrms (VIF input)
(3) Measure the peak value of the detection output level at test point A. (Vp-p)
