General description
The TDA9884 is an alignment-free multistandard (PAL, SECAM and NTSC) vision and
sound IF signal PLL demodulator for positive and negative modulation, including sound
AM and FM processing.
The device is specially prepared for mobile TV applications.

Features
I 5 V supply voltage
I Gain controlled wide-band VIF amplier, AC-coupled
I Multistandard true synchronous demodulation with active carrier regeneration: very
linear demodulation, good intermodulation gures, reduced harmonics, and excellent
pulse response
I Gated phase detector for L and L-accent standard
I Fully integrated VIF VCO, alignment-free, frequencies switchable for all negative and
positive modulated standards via I2C-bus
I Digital acquisition help, VIF frequencies of 33.4 MHz, 33.9 MHz, 38.0 MHz, 38.9 MHz,
45.75 MHz and 58.75 MHz
I 4 MHz reference frequency input: signal from PLL tuning system or operating as
crystal oscillator
I VIF AGC detector for gain control, operating as peak sync detector for negative
modulated signals and as a peak white detector for positive modulated signals
I Mobile mode for negative modulation AGC (VIF and SIF) provides very fast reaction
time
I External AGC setting via pin AGCSW; VIF-AGC and SIF-AGC monitor outputs
I Precise fully digital AFC detector with 4-bit digital-to-analog converter; AFC bits
readable via I2C-bus
I TOP adjustable via I2C-bus or alternatively with potentiometer
I Fully integrated sound carrier trap for 4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz;
controlled by FM-PLL oscillator
I SIF input for single reference QSS mode; PLL controlled
I True split sound mode for sound demodulation at low RF level
I SIF-AGC for gain controlled SIF amplier, single reference QSS mixer able to operate
in high performance single reference QSS mode and in intercarrier mode, switchable
via I2C-bus
I AM demodulator without extra reference circuit
I Alignment-free selective FM-PLL demodulator with high linearity and low noise
TDA9884
I2C-bus controlled multistandard alignment-free IF-PLL for
mobile reception
