Description :

The TDA7421N is a high-performance tuner circuit which integrates AM and FM sections, PLL frequency sinthesizer and IF counter on a single chip.

Use of BICMOS technology allows the implementation of tuning functions with a minimum of external components.Value spread of external components can be fully compensated by means of on-chip electrical adjustment controlled by external µP.

Features

1. HIGH PERFORMANCE FRONT-END IC FOR AM/FM RECEIVERS
2. FULLY INTEGRATED HIGH-SPEED PLL FOR OPTIMIZED RDS APPLICATIONS
3. FM MPX/AM AUDIO OUTPUT, 450kHz AM IF OUTPUT FOR STEREO AM APPLICATIONS
4. AM DOUBLE CONVERSION ARCHITECTURE
5. AM/FM STATION DETECTOR AND DIGITAL IF-COUNTER

AM Test Circuit
