FEATURES
● Suitable for negative vision modulation● Applicable for IF frequencies of 38.9 MHz, 45.75 MHz and 58.75 MHz
● Gain controlled wide band VIF amplifier (AC coupled)
● True synchronous demodulation with active carrier regeneration (ultra-linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response)
● Peak sync AGC for negative modulation
● Video amplifier to match sound trap and sound filter TDA9800
● AGC output voltage for tuner; adjustable take-over point (TOP)
● AFC detector without extra reference circuit
● Alignment-free FM-PLL detector with high linearity
● Stabilizer circuit for ripple rejection and to achieve constant output signals
● 5 to 8 V positive supply voltage range, low power consumption (300 mW at +5 V supply voltage).
