DescriptionESS Technology ES1869 AudioDrive Solution
OverviewThe ES1869 AudioDrive® solution is a mixed-signal single chip that adds 16-bit stereo sound and FM music synthesis to personal computers. It is compliant with Microsoft® PC 97 and PC 98 specifications and WHQL audio requirements. The ES1869 possesses an embedded microcontroller, OPL3™ superset ESFM™ music synthesizer, 16-bit stereo wave ADC and DAC, 16-bit stereo music DAC, MPU-401 UART serial port, dual game port, full Plug and Play support, CD-ROM IDE interface, hardware master volume control, two serial port interfaces to external DSP and external wavetable music synthesizer, I2S Zoom Video interface, DMA control logic with FIFO, and ISA bus interface logic. There are three stereo inputs (typically line, CD audio, and auxiliary line) and a mono microphone input. All of this on a single chip that can be designed into a motherboard, add-on card, or integrated into other peripheral cards such as Fax/Modem, VGA, LAN, I/O, etc.The ES1869 AudioDrive® solution can record, compress, and play back voice, sound, and music with built-in mixer controls. It supports full-duplex operation for simultaneous record and playback using two DMA channels. The ESFM™ synthesizer has extended capabilities within native mode operation providing superior sound and power-down capabilities. It is a register compatible superset of the OPL3 FM synthesizer.The ES1869 AudioDrive® solution supports the full ISA Plug and Play standard. It provides Plug and Play configuration for logical devices: audio, ESFM™ synthesizer, game port, MPU-401, CD-ROM IDE, Modem, and an additional user defined device.The MPU-401 serial port is for interfacing to an external MIDI device.The ES1869 also incorporates Spatializer® VBX™ technology, provided by Desper Products, Inc., a subsidiary of Spatializer Audio Laboratories, Inc. This processor expands the stereo sound field emitted by two speakers to create a resonant 3-D sound environment.The speaker phone application can be implemented either by digital interface through the DSP serial port, or by analog interface through Mono-In and Mono-Out.A DSP serial interface in the ES1869 allows an external DSP to take over ADC or DAC resources.The ES1869 AudioDrive® solution supports telegaming architecture with headsets and includes data paths for host-based Acoustic Echo Cancellation processing.Advanced power management features include suspend/resume from disk or host-independent self-timed powerdown and automatic wake-up. The ES1869 is compliant to the ACPI standard.It is available in an industry-standard 100-pin Plastic Quad Flat Pack (PQFP) and Thin Quad Flat Pack (TQFP) packages.
Key FeaturesSingle, high-performance, mixed-signal, 16-bit stereo VLSI chip High-quality, OPL3 superset ESFM™ music synthesizer IDE CD-ROM interface High-performance DMA supports Demand Transfer and F-type Integrated Spatializer® 3-D VBX™ stereo audio effects technology provided by Desper Products, Inc., a subsidiary of Spatializer Audio Laboratories, Inc.
