TDA4474 General Description
The TDA4474 is an integrated bipolar circuit for fullmultistandard video/ sound IF (VIF/SIF) signalprocessing in TV/VCR and multimedia applications. Thecircuit processes all TV video IF signals with negativemodulation (e.g., B/G standard), positive modulation(e.g., L standard) and the AM, FM/NICAM soundIF signals.
Four IF inputs (2 VIF plus 2 SIF) and the commonpinning with TDA4471 gives flexibility to design auniversal IF module for various applications.

TDA4474 Features
5 V supply voltage; low power consumption
Active carrier generation by FPLL principle(frequency-phase-locked-loop) for true synchronousdemodulation
Very linear video demodulation, good pulse responseand excellent intermodulation figures
VCO circuit is operating on picture carrier frequency,the VCO frequency is switchable for the L' mode
Alignment-free AFC without external referencecircuit, polarity of the AFC curve is switchable
VIF-AGC for negative modulated signals (peak sync. detection) and for positive modulation(peak white/ black level detector)
Tuner AGC with adjustable take over point
Alignment-free quasi parallel sound (QPS) mixer forFM/NICAM sound IF signals
Intercarrier output signal is gain controlled (necessaryfor digital sound processing)
Complete alignment-free AM demodulator with gaincontrolled AF output
Separate SIF-AGC with average detection
Parallel operation of the AM demodulator and QPSmixer (for NICAM-L stereo sound)
Four IF inputs (2 VIFin and 2 SIFin)
Package and relevant pinning is compatible with theTDA4471; simplifies the design of an universal IFmodule
