TDA9815 Key Features
- 5 V supply voltage
- Two switched VIF inputs, gain controlled wide band VIF-amplifier (AC-coupled)
- True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures,
- Robustness for over-modulation better than 105% due to gated phase detector at L/L accent standard
- VCO frequency switchable between L and L accent (alignment external) picture carrier frequency
- 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, peak white detector for L and peak level for
- Tuner AGC with adjustable takeover point (TOP)
- AFC detector without extra reference circuit
- AC-coupled limiter amplifier for sound intercarrier signal with input switch for additional FM signal
