DESCRIPTION
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 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 Very linear video demodulation, good pulse response and excellent intermodulation figures D VCO circuit operates at picture carrier frequency D Alignment-free AFC without external reference circuit, polarity of the AFC curve is switchable D Separate SIF-AGC with average detection D Two independent SIF inputs D Package and relevant pinning is compatible with the multistandard version TDA4470, which simplifies the design of an universal IF module D VIF-AGC with peak sync. detection D Tuner AGC with adjustable take over point Package: SDIP28, SO28 Ordering Information Extended Type Number TDA4472-MSD TDA4472-MFLG3 Package SDIP28 SO28 Remarks Delivery in taped form TELEFUNKEN Semiconductors Rev.
