Video IF Amplifier with FPLL Demodulation

Description

The U 4460 BG is an integrated bipolar circuit for video The circuit processes all TV video IF signals with

IF (VIF) signal processing in TV/VCR and multimedia negative modulation (e.g. B/G standard).

applications.

Features

D Tuner AGC with adjustable take over point
