TDA7021T - FM radio circuit

TDA7021T Description

INTEGRATED CIRCUITS DATA SHEET TDA7021T FM radio circuit for MTS Product speciļ¬cation File under Integrated Circuits, IC01 May 1992 Philips Semicon.
TDA7021T The TDA7021T integrated radio receiver circuit is for portable radios, stereo as well as mono, where a minimum of periphery is important in.

TDA7021T Features

* RF input stage
* Mixer
* Local oscillator
* IF amplifier/limiter
* Frequency detector
* Mute circuit
* MTS compatible QUICK REFERENCE DATA PARAMETER Supply voltage (pin 4) Supply current RF input frequency Sensitivity (e. m. f. ) for

TDA7021T Applications

* using the low-voltage micro tuning system (MTS). The IC has a frequency locked loop (FLL) system with an intermediate frequency of 76 kHz. The selectivity is obtained by active RC filters. The only function to be tuned is the resonant frequency of the oscillator. Interstation noise as well as noise
