TDA9803 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
- AGC output voltage for tuner; adjustable take-over point (TOP)
- AFC detector without extra reference circuit
- Stabilizer circuit for ripple rejection and to achieve constant output signals
- 5 to 8 V positive supply voltage range, low power consumption (230 mW at +5 V supply) GENERAL DESCRIPTION The TDA9803 is
