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
■ 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
■ Covers all Japanese, European and US bands.
