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.
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 (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

[1] Values of video and sound parameters can be decreased at VP = 4.5 V.
[2] AC load; CL < 20 pF and RL > 1 k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound
carrier traps.
[3] Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps.
[4] The sound carrier trap can be bypassed by setting the I2C-bus bit W2[0] to logic 0; see Table 23. In this way the full composite video
spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p).
[5] Measurement using 200 kHz high-pass filter, 5 MHz low-pass filter and subcarrier notch filter (“ITU-T J.64”).
[6] To match the AFC output signal to different tuning systems a current output is provided. The test circuit is given in Figure 19. The
AFC steepness can be changed by resistors R1 and R2.
[7] With single-ended load for fIF < 45 MHz RL 1 kand CL 5 pF to ground and for fIF = 45 MHz to 60 MHz RL = 1 kand CL 3 pF to
ground.
[8] This parameter is not tested during production and is only given as application information.
[9] Noise level is measured without input signal but AGC adjusted corresponding to the given input level.
[10] Set with AGC nominal output voltage as reference. For C/N measurement switch input signal off.
[11] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum
FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer.
