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
Active carrier generation by FPLL principle
(frequency–phase–locked–loop) for true
synchronous demodulation
Very linear video demodulation, good pulse
response and excellent intermodulation figures
VCO is operating on picture carrier frequency
Alignment–free AFC, no external reference circuit
VIF–AGC with peak sync detection
Tuner AGC with adjustable take over point
5V supply voltage; low power consumption
Relevant pinning is compatible with the
TDA 4474 /71 video–/sound IF combination
Package:
28 pin shrink–dual–inline–plastic (SDIP28)
