FEATURES
● Suitable for negative and positive vision modulation● Gain controlled 3-stage IF amplifier; suitable for VIF frequencies up to 60 MHz
● 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, e.g. B/G standard
● Peak white AGC for positive modulation, e.g. L standard
● Video amplifier to match sound trap and sound filter TDA9802
● 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)
