General Description
The CS9236 is a complete General MIDI wavetable mu-
sic synthesizer on a single integrated circuit. The MIDI
interpreter, synthesis engine, effects processing, and all
RAM and ROM memories (including the wavetable sam-
ple 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 sam-
ple set including 128 melodic instruments and 47
percussion sounds. The synthesis engine is capable of
generating up to 32 simultaneous notes. Digital rever-
beration and chorusing effects are included on-chip.
The CS9236 is the ideal low-cost General MIDI synthe-
sizer solution for a number of applications, including
multimedia PCs, game machines, karaoke, and low-cost
musical instruments and MIDI sound modules.
