TDA9882

Alignment-free multistandard vision and QSS FM sound

IF PLL demodulator

Rev. 01 — 16 November 2004

Product data sheet

1. General 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

■ 5 V supply voltage

■ Gain controlled wideband Vision Intermediate Frequency (VIF) ampliﬁer; AC-coupled

■ Multistandard true synchronous demodulation with active carrier regeneration: very

linear demodulation, good intermodulation ﬁgures, reduced harmonics and excellent

pulse response

■ Gated phase detector for L and L-accent standard

■ 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

■ 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)

■ 4 MHz reference frequency input signal from Phase-Locked Loop (PLL) tuning system

or operating as crystal oscillator

■ VIF Automatic Gain Control (AGC) detector for gain control; operating as peak sync

detector for negative modulated signals and as a peak white detector for positive

modulated signals

■ VIF AGC monitor output at pin VAGC

■ Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit

digital-to-analog converter

■ TakeOver Point (TOP) adjustable with potentiometer

■ Fully integrated sound carrier trap for 4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz;

controlled by FM PLL oscillator

■ Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode; PLL

controlled

■ SIF AGC for gain controlled SIF ampliﬁer; single reference QSS mixer able to operate

in high performance single reference QSS mode

■ AM sound demodulator without extra reference circuit

■ Alignment-free selective FM PLL demodulator with high linearity and low noise.
