TDA9802 Key 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,
- 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
- 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
