TDA9806 Key Features
- 5 V supply voltage
- Gain controlled wide band VIF-amplifier (AC-coupled)
- True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures,
- Separate video amplifier for sound trap buffering with high video bandwidth
- VIF AGC detector for gain control, operating as peak sync detector for B/G
- Tuner AGC with adjustable takeover point (TOP)
- AFC detector without extra reference circuit
- AC-coupled limiter amplifier for sound intercarrier signal
- Alignment-free FM-PLL demodulator with high linearity, switchable de-emphasis for FM
- Stabilizer circuit for ripple rejection and to achieve constant output signals. ORDERING INFORMATION PACKAGE TYPE NUMBER
