1 / 11 page U4479B Preliminary Information TELEFUNKEN Semiconductors Rev. A2, 14-Jan-98 1 (11) 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 Ordering Information Extended Type Number Package Remarks U4479B-MFLG3 SO28 Taped and reeled |
