TDA9809M
Key Features
- 5 V supply voltage
- Applicable at Intermediate Frequencies (IFs) of 38.9 and 45.75 MHz
- Gain controlled wideband Video IF (VIF) amplifier (AC-coupled)
- Robustness for over-modulation better than 105% due to PLL bandwidth control for negative modulation standards
- VIF AGC (Automatic Gain Control) detector for gain control, operating as peak sync detector for negative modulation standards
- Tuner AGC with adjustable TakeOver Point (TOP)
- AFC (Automatic Frequency Control) detector without extra reference circuit
- AC-coupled limiting amplifier for sound intercarrier signal
- Alignment-free FM PLL (Phase-Locked Loop) demodulator with high linearity; integrated de-emphasis resistor
- Integrated level detector
