ES1869 Audio Drive®Solution
Product Brief
DESCRIPTION
The ES1869 Audio Drive® solution is a single, mixed-signal chip that adds 16-bit stereo sound and FM music synthesis to personal computers. It is compliant with the Microsoft® PC 97 and PC 98 specifications and WHQL audio requirements. The ES1869 posss an embedded microcontroller, an OPL3™ supert ESFM TM music synthesizer, a 16-bit stereo wave ADC and DAC, 16-bit stereo music DAC, MPU-401 UART mode rial port, dual game port, full plug-and-play support, CD-ROM IDE interface, hardware master volume control, two rial 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. This single chip can be designed into a motherboard, and add-on card, or integrated into other peripheral cards such as Fax/Modem, VGA, LAN, I/O, etc.
The ES1869 Audio Drive 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 supert to the OPL3 FM synthesizer.
The ES1869Audio Drive 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, IDE CD-ROM, MODEM, and an additional ur-defined device. The MPU-401 rial port is for interfacing to an external MIDI device.
The integrated 3D audio effects processor us Spatializer®VBX™ technology, provided by Desper Products, Inc. a subsidiary of Spatializer Audio Laboratories, Inc. This processor expands the sound field emitted by two speakers to create a resonant 3D sound environment.
The speakerphone application can be implemented either by digital interface through the DSP rial port, or by analog interface through Mono-In and Mono-Out.
A DSP rial interface in the ES1869 allows an external DSP to take over ADC or DAC resources.
The ES1869Audio Drive solution supports telegaming architecture with headts and includes data paths for host-bad acoustic echo cancellation processing.
Advanced power management features include suspend/resume from disk or host-independent lf-timed power-down and automatic wake-up. The ES1869 is compliant with the ACPI standard.
The ES1869 is available in an industry-standard 100-pin plastic quad flat pack (PQFP) package.FEATURES
