1. General description
The TEA5880TS stereo FM radio IC dramatically reduces the printed-circuit board area
(only 100 mm2) 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
■No alignments necessary
■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
■No external FM discriminator needed due to full integration
■Built-in adjacent channel interference total reduction (no 114 kHz, no 190 kHz)
■The levelof 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
■Very high sensitivity due to integrated low noise RF input amplifier
■RF Automatic Gain Control (AGC) circuit
■Standby mode for power-down, no power switch circuitry required
■2.7 V minimum supply voltage
■MPX output for RDS
■3-wire bus
■Incombination with the host, fast, low power operation of preset mode, manual search,
automatic search and automatic store are possible
■Host can be in Sleep mode after tuning; a minute retuning is recommended to
compensate for temperature and voltage fluctuations
■Covers all Japanese, European and US bands.
