TEA5880TS

TEA5880TS Integrated FM stereo radio IC for host processor tuning in handheld applications Rev. 02 — 26 April 2004 Preliminary data sheet 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 s s s s s s s s s s s s s s s s 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...
