DVB-Cable IF Converter and
Full Multi-Standard Video-/Sound IF Processing
Description
The U4479B is a bipolar circuit for the processing of
cable DVB IF (Digital Video Broadcasting) and multi-
standard analog TV IF signals. The combi circuit
processes QAM modulated IF signals, all TV video IF
with negative/ positive modulation and the FM/ NICAM,
AM sound IF signals. With 5 V supply voltage the IC is
suitable for cable DVB receiver (set top boxes).
Features
D 5 V supply voltage; low power consumption
D DVB signal processing with a converter for the 2nd IF;
VCO is controlled by an external PLL
D Active carrier generation by FPLL principle
(frequency-phase-locked-loop) for true synchronous
demodulation in the “analog mode”
D Switchable VCO frequency (33.4/38.9/43.0 MHz)
D Very linear video demodulation, good pulse response
and excellent intermodulation figures
D Bandwidth of the output signal 10 MHz (–1 dB) in
DVB mode
D Alignment-free AFC
D AGC for negative modulation signals (peak sync
detection) and for positive modulation (peak white/
black level detector)
D AGC with average detection for the QAM modulated
DVB signal, reference level is adjustable
D Tuner AGC with adjustable take over point
D Alignment-free quasi parallel sound (QPS) mixer for
FM/NICAM sound IF signals
D Complete alignment-free AM demodulator with gain
controlled AF output
D Separate SIF-AGC with average detection
D Parallel operation of the AM demodulator and QPS
mixer (for NICAM-L stereo sound)
D Two IF inputs for DVB-/Analog Video IF
D One sound IF input
