Related Literature and Crystal Reference Designs

A number of related documents are available from Crystal Semiconductor. These include the CS9233 Microcontroller Firmware data sheet, the CRD9233-1 ISA Wavetable Sound Card Reference Design data sheet, the CRD9233-3 Wavetable Synthesizer Daughtercard Reference Design data sheet, the CS4110/CS4111 Wavetable Sample ROM data sheet, the CS4112 Wavetable Sample ROM data sheet, the CS4331 18-bit Stereo DAC data sheet, the CS4232 Multimedia CODEC data sheet, the CS8905/CS8905A Digital Musical Effects Processor data sheet, and an applications note titled "A Tutorial on MIDI and Wavetable Synthesis" by Jim Heckroth.

The CS9233 Microcontroller Firmware Data Sheet provides a description of the functions provided in the CS9233 firmware available from Crystal. This firmware is used in conjunction with the Crystal 1Mx8 sample ROM (CS4112), or the 4Mx8 sample ROM set (CS4110 plus CS4111). The firmware data sheet includes instrument lists for the 1Mx8 sample set and 4Mx8 sample set, complete MIDI implementation data, Self Test data, and sample downloading information.

The CRD9233-1 Reference Design is a complete ISA sound card design utilizing the CS4232, CS9233, CS4112 and CS4331. This high performance audio adapter card includes four different CD-ROM interfaces, and is Plug and Play configurable. The wavetable synthesizer implementation on the CRD9233-1 features the full General MIDI instrument set plus GS variations in sample ROM, and supports downloadable samples with a 512Kx8 sample memory DRAM.

The CRD9233-3 Reference Design is a complete wavetable daughter card design utilizing the CS9233, the CS4112, the CS4331, and the CS8905/CS8905A effects processor. This design utilizes the de-facto standard WaveBlaster 26-pin header pin-out. The high quality digital reverb and chorus effects provided by the CS8905A are adjustable on a per-MIDI channel basis through the CS9233 MIDI interface.

Crystal Reference Design packages include functional circuit boards, data sheets, schematics, Bill of Materials, layout information, and any applicable software.
