Philips TEA5880TS - Manual

1. 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.
2. Features
