TEA6101 Datasheet (NXP) - Antenna diversity circuit

TEA6101, Antenna diversity circuit

TEA6101/T Intended for multi-antenna FM car radio reception (antenna diversity system), the TEA6101/T selects the most favourable signal from one of up to four antennae.

Founded upon audible signal disturbance the criteria are derived from two signals: high frequency components (e.g.

spikes due to

TEA6101 Features

* Ability to switch between up to four antennae

* Switching signal derived from two signals: the audio and the level signals

* Floating switching threshold adjusts switching rate to prevailing circumstances:

* increasing threshold due to excessive noise

* incr
