General description
The Integrated Circuit (IC) is suitable for Intermediate Frequency (IF) processing including
global multistandard Analog TV (ATV), Digital Video Broadcast (DVB) and mono FM radio
using only 1 IC and 1 to 3 xed Surface Acoustic Waves (SAWs) (application dependent).
TDA9898 including L and L-accent standard. TDA9897 without L and L-accent standard.

Features
2.1 General
I 5 V supply voltage
I I2C-bus control over all functions
I Four I2C-bus addresses provided; selection by programmable Module Address (MAD)
I Three I2C-bus voltage level supported; selection via pin BVS
I Separate gain controlled ampliers with input selector and conversion for incoming IF
[analog Vision IF (VIF) or Sound IF (SIF) or Digital TV (DTV)] allows the use of
different lter shapes and bandwidths
I All conventional ATV standards applicable by using DTV bandwidth window
[Band-Pass (BP)] lter
I Easy to use default settings for almost every standard provided, selectable via I2C-bus
I Two 4 MHz reference frequency stages; the rst one operates as crystal oscillator, the
second one as external signal input
I Stabilizer circuit for ripple rejection and to achieve constant output signals
I Smallest size, simplest application
I ElectroStatic Discharge (ESD) protection for all pins
2.2 Analog TV processing
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 Internal Nyquist slope processing; switch-off able for alternative use of inexpensive
Nyquist slope SAW lter with additive video noise improvement
I Gated phase detector for L and L-accent standards
I Fully integrated VIF Voltage-Controlled Oscillator (VCO), alignment-free, frequencies
switchable for all negative and positive modulated standards via I2C-bus
I VIF Automatic Gain Control (AGC) detector for gain control; operating as a peak sync
detector for negative modulated signals and as a peak white detector for positive
modulated signals
TDA9897; TDA9898
