TDA9882
description
The TDA9882 is an alignment-free multistandard (PAL, SECAM and NTSC) vision and sound IF signal PLL demodulator for positive and negative modulation, including Quasi Split Sound (QSS) FM and AM sound processing.
2. Features s 5 V supply voltage s Gain controlled wideband Vision Intermediate Frequency (VIF) amplifier; AC-coupled s Multistandard true synchronous demodulation with active carrier regeneration: very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response s Gated phase detector for L and L-accent standard s Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free, frequencies switchable via logic pin VIF0 and pin QSSO with resistor for negative and positive modulated standards s Digital acquisition help circuit, VIF frequencies of 38.9 MHz and 45.75 MHz (negative modulation); 38.9 MHz and 33.9 MHz (positive modulation) s 4 MHz reference frequency input signal from Phase-Locked Loop (PLL) tuning system or...
