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.

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 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

I All conventional ATV standards applicable by using DTV bandwidth window (SAW)

ﬁlter

I Two 4 MHz reference frequency stages; the ﬁrst 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 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 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
