U4460BG

Video IF Amplifier with FPLL Demodulation

Description

The U 4460 BG is an integrated bipolar circuit for video

IF (VIF) signal processing in TV/VCR and multimedia

applications.

The circuit processes all TV video IF signals with

negative modulation (e.g. B/G standard).

Features

D

Active carrier generation by FPLL principle

D

Tuner AGC with adjustable take over point

D

5V supply voltage; low power consumption

D

Relevant pinning is compatible with the

(frequency鈥損hase鈥搇ocked鈥搇oop) for true

synchronous demodulation

D

Very linear video demodulation, good pulse

response and excellent intermodulation figures

D

VCO is operating on picture carrier frequency

D

Alignment鈥揻ree AFC, no external reference circuit

D

VIF鈥揂GC with peak sync detection
