ENSONIQ ES-5530 "OPUS" Multimedia Sound Chip
The Ensoniq ES-5530 OPUS chip was used on Ensoniq's OEM Soundscape PC audio card. It was primarily found in Gateway 2000 computers as an Ensoniq OEM sound board. Sound cards based on this chip were never available at retail. Soundscapes based upon this chip had similar capabilities to their retail Soundscape counterparts, which were themselves based upon the Ensoniq wavetable synthesis chip pair 'Otto' and 'Sequoia'.
The chip was a low-cost, highly integrated wavetable synthesis solution designed for the burgeoning multimedia PC market. It supported Microsoft MPC Level I & II standards and was Sound Blaster compatible. It was manufactured on a 0.8 micrometer double-metal VLSI CMOS process.
The major features of OPUS were:
- Wavetable synthesis with 32 independent voices
- Oversampled 18-bit d/a converter
- Integrated AT bus interface including:
- Built in flexible CD-ROM interface
- Built in joystick interface
- Real time digital filters
- 5 channel stereo serial communication port - 3 inputs 2 outputs
- Industry standard data formats
