DESCRIPTION
B/G standard), positive modulation (e.g. L standard) and the AM, FM/NICAM sound IF signals. Specially two video IF inputs (2 x VIF) in combination with one sound IF input (1 x SIF) and the common pinning with the TDA4474 gives flexibility to design a universal IF module for various applications. FEATURES
D 5V supply voltage; low power consumption D Active carrier generation by FPLL principle D Intercarrier output signal is gain controlled (necessary for digital sound processing) D Complete alignment–free AM demodulator with (frequency–phase–locked–loop) synchronous demodulation for true gain controlled AF output D Separate SIF–AGC with average detection D Parallel operation of the AM demodulator and D Very linear video demodulation, good pulse response and excellent intermodulation figures D VCO circuit is operating on picture carrier QPS mixer (for NICAM–L stereo sound) D Two video IF inputs (2 x VIFin) D One sound IF input (1 x SIFin) D Package and relevant pinning is com...
