TDA9897_09 Overview

Multistandard hybrid IF processing

TDA9897; TDA9898
Multistandard hybrid IF processing
Rev. 04 — 25 May 2009
Product data sheet
1. 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 fixed Surface Acoustic Waves (SAWs) (application dependent).
TDA9898 includes, TDA9897 excludes L and L-accent standard.

C-bus addresses provided; selection by programmable Module Address (MAD)
Three I
2
C-bus voltage level supported; selection via pin BVS
Separate gain controlled amplifiers 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 filter shapes and bandwidths
All conventional ATV standards applicable by using DTV bandwidth window (SAW)
filter
Two 4 MHz reference frequency stages; the first one operates as crystal oscillator, the
second one as external signal input
Stabilizer circuit for ripple rejection and to achieve constant output signals
Smallest size, simplest application
ElectroStatic Discharge (ESD) protection for all pins

2.2 Analog TV processing
I
Gain controlled wideband VIF amplifier; AC-coupled
I
Multistandard true synchronous demodulation with active carrier regeneration: very
linear demodulation, good intermodulation figures, reduced harmonics and excellent
pulse response
I
Integrated Nyquist processing, providing additionally image suppression for high
adjacent channel selectivity
I
Optional use of conventional Nyquist filter to support a wide range of applications
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 I

C-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
