Test Conditions
V1. Circuit current [I17]
(1) External AGC (V17 = 1.5V)
(2) RF AGC VR MAX
(3) Connect an ammeter to the VCC and measure the incoming current to pin 17.
V2. V3. Maximum RF AGC voltage, Minimum RF AGC voltage [V14H, V14L]
(1) Internal AGC
(2) Input a 38.0MHz, 10mVrms, continuous wave to the VIF input pin.
(3) Adjust the RF AGC VR (resistance max.) and measure the maximum RF AGC voltage.
(4) Adjust the RF AGC VR (resistance min.) and measure the minimum RF AGC voltage.
(3), (4) Measuring point F
V4. Input sensitivity [Vi]
(1) Internal AGC
(2) fp = 38.0MHz 400Hz 40% AM (VIF input)
(3) Turn off the SW1 and put 100k
through.
(4) Measure the VIF input level at which the 400Hz detection output level at test point A becomes 0.7Vp-p.
V5. AGC range [GR]
(1) Apply the VCC voltage to the external AGC, If AGC (pin 15).
(2) In the same manner under the same conditions as for V4 (input sensitivity), measure the VIF input level at which
the detection output level becomes 0.7Vp-p. Vil
(3) GR = 20log
dB *Vi: Input sensitivity
V6. Maximum allowable input [Vi max]
(1) Internal AGC
(2) fp = 38.0MHz 15kHz 78% AM (VIF input)
(3) VIF input level at which the detection output level at test point A becomes video output (VO) ±1dB.
V7. No-signal video output voltage [V4]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 15).
(2) Measure the DC voltage of VIDEO output (A).
V8. Sync. signal tip voltage [V6tip]
(1) Internal AGC
(2) Input a 38.0MHz, 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 = 38.0MHz 15kHz 78% AM
Vi = 10mVrms (VIF input)
(3) Measure the peak value of the detection output level at test point A. (Vp-p)
