Circuit Description
The following function units are integrated in this circuit
combination for video-IF processing:
Three symmetric, highly stable, gain controlled wide-
band amplifier, quasi galvanic coupling eliminates
feed back
Video carrier controlled demodulator of high linearity
Polarity switch over for video
Video output amplifier with low-pass characteristics,
limiter for ultra black and inverter for ultra white
interference
High impedance, interference free controlled voltage
facilities, best possible AGC time constant with small
storage capacitor
Controlled discharge circuit for fast gain control
With VTR - operation the video output level is
according to the ultra white level in B/G, ultra black
level in L
Absolute Maximum Ratings
Reference point Pin 3, unless otherwise specified
