Description

The CS9236 is a complete General MIDI wavetable music synthesizer on a single integrated circuit. The MIDI interpreter, synthesis engine, effects processing, and all RAM and ROM memories (including the wavetable sample ROM) are included on-chip. This all-digital device receives a standard serial MIDI data stream, and outputs a stereo 16-bit digital audio stream at 44.1kHz. The CS9236 digital audio output is directly compatible with the Crystal CS4236B/37B/38B multimedia CODECs, and with the CS4333 DAC.

The CS9236 features a high quality General MIDI sample set including 128 melodic instruments and 47 percussion sounds. The synthesis engine is capable of generating up to 32 simultaneous notes. Digital reverberation and chorusing effects are included on-chip.

The CS9236 is the ideal low-cost General MIDI synthesizer solution for a number of applications, including multimedia PCs, game machines, karaoke, and low-cost musical instruments and MIDI sound modules.
