1 / 103 page 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 TDA9897; TDA9898 Multistandard hybrid IF processing Rev. 03 — 11 January 2008 Product data sheet |
