FEATURES

• 5 V supply voltage

• Gain controlled wide-band 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 for all

negative and positive modulated standards via I2C-bus

• Digital acquisition help, VIF frequencies of 33.4, 33.9,

38.0, 38.9, 45.75, and 58.75 MHz

• 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

• Mobile mode for negative modulation AGC (VIF and

SIF) provides very fast reaction time

• External AGC setting via pin AGCSW; VIF-AGC and

SIF-AGC monitor outputs

• Precise fully digital Automatic Frequency Control (AFC)

detector with 4-bit digital-to-analog converter, AFC bits

readable via I2C-bus

• TakeOver Point (TOP) adjustable via I2C-bus or

alternatively with potentiometer

• Fully integrated sound carrier trap for 4.5, 5.5,

6.0, and 6.5 MHz, controlled by FM-PLL oscillator

• Sound IF (SIF) input for single reference Quasi Split

Sound (QSS) mode, PLL controlled

• True split sound mode for sound demodulation at low RF

level

• SIF-AGC for gain controlled SIF amplifier, single

reference QSS mixer able to operate in high

performance single reference QSS mode and in

intercarrier mode, switchable via I2C-bus

• AM demodulator without extra reference circuit

• Alignment-free selective FM-PLL demodulator with high

linearity and low noise

• Four selectable I2C-bus addresses

• I2C-bus control for all functions

• I2C-bus transceiver with pin programmable Module

Address (MAD).

GENERAL DESCRIPTION

The TDA9884TS 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.
