FUNCTIONAL DESCRIPTION Vision input vision amplifier consists three AC-coupled differential amplifier stages; each stage comprises controlled feedback network means emitter degeneration. tuner automatic control voltage maintain video output signal constant level generated according transmission standard. Since TDA9800 suitable negative modulation only peak-sync level detected. detector charges discharges capacitor gain tuner gain. capacitor voltage transferred internal control signal, tuner generate tuner output current (open-collector output). tuner voltage take over point adjusted This allows tuner filter matched achieve optimum input level. Frequency detector, phase detector video demodulator amplifier output signal frequency detector phase detector. During acquisition frequency detector produces current which proportional frequency difference between input signal. After frequency lock-in phase detector produces current proportional phase difference between input signal. loop filter current either frequency detector phase detector converted into voltage, which controls frequency. video demodulator linear multiplier, designed distortion wide bandwidth. vision input signal multiplied in-phase component output. demodulated output signal integrated low-pass filter MHz) video amplifier suppression carrier harmonics. travelling wave divider operates with symmetrically-connected reference LC-circuit, operating double vision carrier frequency. Frequency control performed internal varicap diode. voltage frequency actual frequency double vision carrier frequency, also amplified converted output current. signal divided-by-two travelling wave divider, which generates differential output signals
