1 / 16 page TDA4470-M Preliminary Information TELEFUNKEN Semiconductors Rev. A2, 15-Oct-96 1 (16) Multistandard Video-IF and Quasi Parallel Sound Processing Description The TDA4470 is an integrated bipolar circuit for multi- standard video/sound IF (VIF/SIF) signal processing in TV/VCR and multimedia applications. The circuit processes all TV video IF signals with negative modulation (e.g., B/G standard), positive modulation (e.g., L standard) and the AM, FM/NICAM sound IF signals. Features D 5 V supply voltage; low power consumption D Active carrier generation by FPLL principle (frequency-phase-locked-loop) for true synchronous demodulation D Very linear video demodulation, good pulse response and excellent intermodulation figures D VCO circuit operates at picture carrier frequency, the VCO frequency is switchable for L’-mode D Alignment-free AFC without external reference circuit, polarity of the AFC curve is switchable D VIF-AGC for negative modulated signals (peak sync. detection) and for positive modulation (peak white/ black level detector) D Tuner AGC with adjustable take over point D Alignment-free quasi parallel sound (QPS) mixer for FM/NICAM sound IF signals D Intercarrier output signal is gain controlled (necessary for digital sound processing) D Complete alignment-free AM demodulator with gain controlled AF output D Separate SIF-AGC with average detection D Two independent SIF inputs D Parallel operation of the AM demodulator and QPS mixer (for NICAM-L stereo sound) D Package and relevant pinning is compatible with the single standard version TDA4472, which simplifies the design of an universal IF module Package: SDIP28, SO28 Ordering Information Extended Type Number Package Remarks TDA4470-MSD SDIP28 TDA4470-MFLG3 SO28 Delivery in taped form |
