Multistandard IF amplifier and
demodulator
Product specification
TDA8349A
GENERAL DESCRIPTION
The TDA8349A is a multistandard IF amplifier and demodulator with AGC and AFC functions for television receivers.
The device has a video recognition circuit and a video switch for internal or external video for full SCART applications.
FEATURES
Full-range gain-controlled wideband IF amplifier up to 60 MHz
Wide-band video amplifier with good linearity and a class AB output stage to ensure a very low output impedance
Supply independent video output level
Small second harmonic IF output
AGC circuit which operates on top sync level (negative modulation) or on white level (positive modulation) or on top
level (MAC) with reduced sensitivity for high sound carriers
AFC circuit with an internal 90° phase shift circuit, a sample-and-hold circuit for negatively modulated signals to reduce
video dependent AFC information and an analog or digital output
Video recognition possibility based on horizontal pulse duty cycles
Video switch for selection of internal or external video signals
Wide supply voltage range and ripple rejection
Requires few external components
Tuner AGC output for npn and pnp tuners
