Overview
TDA7703R Highly integrated tuner for AM/FM car radio Features ■ ■ ■ ■ ■ ■ ■ Fully integrated VCO for world tuning High performance PLL for fast RDS system AM/FM mixers with high image rejection Integrated AM-LNA and AM-PINDIODE Automatic self alignment for image rejection Digital IF signal processing, high performance and drift-free Integrated IF-filters with high selectivity, high dynamic range and FM adaptive bandwidth control RDS demodulation with group and block synchronization High performance stereodecoder with noiseblanker I2C bus controlled Single 5 V supply LQFP44 package LQFP44 ■ ■ ■ ■ ■ It contains mixers and IF amplifiers for AM and FM, fully integrated VCO and PLL synthesizer, IF-processing including adaptive bandwidth control (FM), stereo decoder and RDS decoder on a single chip.
The utilization of digital signal processing results in numerous advantages against today's tuners: – Very low number of external components – Very small space occupation and easy application – Very high selectivity due to digital filters – High flexibility by software control – Automatic image rejection alignment.
Description The TDA7703R highly integrated tuner (HIT44) is part of a family of tuners for carradio applications.
