Description
TDA8349A
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 a.
