TDA7703R
Overview
The TDA7703R highly integrated tuner (HIT44) is part of a family of tuners for carradio applications.
- 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.
