Description
The TDA9811 is an integrated circuit for multistandard vision IF signal processing and sound AM, with single reference QSS-IF in TV and VCR sets.
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, reduced harmonics, excellent pulse response).
- 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 freq.
