Polyphonic Ringtone ICs
This series of chips is designed for the ringtone application of mobile phones with MIDI music and ADPCM speech synthesis. The ICs consist of all key components including baseband MCU interface, FIFO buffers, GM compliant wavetable sound set, MIDI sequencer, wavetable/ADPCM synthesizer, DAC and power amplifier for direct driving 8-ohm loudspeakers. Synchronization among MIDI, SFX, LED, and Motor is supported. Application Program Interface (API) source code is provided for the CPU to control the ringtone ICs. Easy-to-use S/W and H/W development environment is available to customers and content providers.
