Integrated Circuits (ICs) are suitable for intermediate frequency (IF) processing, including worldwide multi-standard Analog Television (ATV), Digital Video Broadcasting (DVB) and Mono FM Radios using only 1 IC and 1 to 3 fixed surfaces Sonic (saw) (depending on application).
TDA9898 includes L and L-accent standards. TDA9897 has no L and L-accent standard
Features of TDA9898 - Multi-Standard Hybrid IF Processing:

5 V supply voltage
All functions of I2C bus control provide 4 I2C bus addresses; selection of programmable module address (MAD) supports three I2C bus voltage levels; independent gain control via pin BVS selection of input selector and conversion of incoming IF amplifier
[Analog Visual IF (VIF) or Sound Intermediate Frequency (SIF) or Digital Television (DTV)] Allows the use of different filter shapes and bandwidths for all conventional ATVs applicable to the standard using the bandwidth window of DTV
[Band Pass (BP)] filter with easy-to-use default settings, almost every standard provided, two frequency reference stages selected via the I2C bus, the first to operate, the crystal oscillator second for external signal input ripple rejection and Stabilizer circuit for constant output signal Minimum size, Easiest application Electrostatic discharge (ESD) protection for all pins

Analog TV Processing Gain Controlled Broadband VIF Amplifier, AC Coupled Multi-Standard Active Carrier Regeneration: True Synchronous Demodulation Very Linear Demodulation, Good Intermodulation Figures, Harmonic Reduction and Excellent Impulse Response Internal Nyquist Ramp processing; shutdown using an inexpensive alternative to Nyquist slope SAW filter additive video noise improvement for L and L-accent standard gated phase detector fully integrated VIF voltage controlled oscillator (VCO), aligned, Frequency switching for all negative and positive modulations via the I2C bus scalar VIF gain control for automatic gain control (AGC) detectors; operates as a peak synchronous detector with negative modulation signals and positive white peak detector modulation signals
