General description

The TDA9881 is an alignment-free multistandard (PAL and NTSC) vision and sound

IF signal PLL demodulator for negative modulation, including Quasi Split Sound (QSS) or

intercarrier FM processing.

2.

Features

s 5 V supply voltage

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

s Multistandard true synchronous demodulation for negative modulated standards with

active carrier regeneration: very linear demodulation, good intermodulation ﬁgures,

reduced harmonics and excellent pulse response

s Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free, frequencies

switchable via logic pin VIF0 and pin QSSO with resistor

s Digital acquisition help circuit, VIF frequencies of 38.0 MHz, 38.9 MHz, 45.75 MHz and

58.75 MHz

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

or operating as crystal oscillator

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

detector

s VIF AGC monitor output at pin VAGC

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

digital-to-analog converter

s TakeOver Point (TOP) adjustable with potentiometer

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

controlled by FM PLL oscillator

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

controlled

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

in high performance single reference QSS mode or in intercarrier mode; switchable via

SIF input pins

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

3.

Applications

s TV, VTR, PC and Set-Top Box (STB) applications.
