General description
The TEA5880TS stereo FM radio IC dramatically reduces the printed-circuit board area
(only 100 mm
2
) needed to integrate FM radio functionality into portable devices. This
makes it invaluable for any application where space is at a premium.
Relying on a system host processor for radio tuning, the TEA5880TS is ideally suited for
powerful devices such as PDAs, notebooks, portable CD and MP3 players.

■
Complete adjustment-free stereo decoder; no external crystal required
■
Fully integrated MPX VCO circuit
■
Fully integrated low IF selectivity and demodulation
■
The full integration level means no or few external components required
■

■
Built-in adjacent channel interference total reduction (no 114 kHz, no 190 kHz)
■
The level of the incoming signal at which the radio must lock is software programmable
■
Due to new tuning concept, the tuning is independent of the channel spacing
