TEA5880TS
Integrated FM stereo radio IC for host processor tuning in
handheld applications
Rev. 02 — 26 April 2004
The TEA5880TS stereo FM radio IC dramatically reduces the printed-circuit board area
2
(only 100 mm ) 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.
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 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
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
In combination 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
