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)
● 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 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
● Alignment-free FM radio AFC detector with external resonator
● RIF (Radio IF) amplifier for 10.7 MHz
● Stabilizer circuit for ripple rejection and to achieve constant output signals
● ESD (Electrostatic Discharge) protection for all pins.
