FEATURES
● 5 V supply voltage (9 V supply voltage for TDA9808 (DIP20) only)● Applicable for IFs (Intermediate Frequencies) of 38.9 MHz, 45.75 MHz and 58.75 MHz
● Gain controlled wide band Video IF (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 Phase Locked Loop (PLL)-bandwidth control at negative modulated standards
● VIF Automatic Gain Control (AGC) detector for gain control, operating as peak sync detector
● Tuner AGC with adjustable TakeOver Point (TOP)
● Automatic Frequency Control (AFC) detector without extra reference circuit
● AC-coupled limiter amplifier for sound intercarrier signal
● Alignment-free FM-PLL demodulator with high linearity
● Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode (PLL controlled); SIF AGC detector for gain controlled SIF amplifier; single reference QSS mixer for high performance
● Electrostatic Discharge (ESD) protection for all pins.
