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
with degree phase difference independent frequency.
Video amplifier, buffer noise clipping
video amplifier wide bandwidth operational amplifier with internal feedback. nominal positive modulated video signal (p-p) present composite video output (pin 13). input impedance wideband buffer amplifier (with internal feedback) suitable ceramic sound trap filters. CVBS output (pin provides positive video signal (p-p). Noise clipping provided internally.
Sound demodulation
sound intercarrier signal through limiter amplifier before demodulated. This achieves high sensitivity high suppression. limiter amplifier consists seven internal AC-coupled stages, minimizing offset. FM-PLL demodulator consists RC-oscillator, loop filter phase detector. oscillator frequency locked intercarrier signal from limiter amplifier. result this locking, RC-oscillator frequency-modulated.
modulating signal voltage signal) used control oscillator frequency. this, FM-PLL operates demodulator. audio frequency amplifier with internal feedback designed high gain high common mode rejection. low-level signal output from FM-PLL demodulator amplified buffered low-ohmic audio signal output stage (pin external decoupling capacitor removes voltage from audio amplifier input.

SOLDERING Introduction
There soldering method that ideal packages. Wave soldering often preferred when through-hole surface mounted components mixed printed-circuit board. However, wave soldering always suitable surface mounted ICs, printed-circuits with high population densities. these situations reflow soldering often used.
