TDA9897; TDA9898

Multistandard hybrid IF processing

Rev. 03 — 11 January 2008

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 including L and L-accent standard. TDA9897 without L and L-accent standard.

2. 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

[Band-Pass (BP)] ﬁlter

I Easy to use default settings for almost every standard provided, selectable via I²C-bus

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 wide-band 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 Internal Nyquist slope processing; switch-off able for alternative use of inexpensive

Nyquist slope SAW ﬁlter 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
