DESCRIPTION
The TDA 7511 is a high performance tuner circuit for
AM/FM car radio. It contains mixers, IF amplifiers, de-
modulators for AM and FM, quality detection, ISS fil-
ter and PLL synthesizer with IF counter on a single
chip.
Use of BICMOS technology allows the implementa-
tion of several tuning functions and a minimum of ex-
ternal components.
