Alignment-free vision and FM sound IF PLL demodulator for
negative modulated TV standards
Rev. 01 — 16 November 2004
Product data sheet
1. 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.
