ES1869
AudioDrive® Solution
Product Brief
DESCRIPTION
The ES1869 AudioDrive® 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
possesses an embedded microcontroller, an OPL3™ superset
ESFMTM music synthesizer, a 16-bit stereo wave ADC and DAC, 16-
bit stereo music DAC, MPU-401 UART mode 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. 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 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 to 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, IDE CD-
ROM, MODEM, and an additional user-defined device. The MPU-
401 serial port is for interfacing to an external MIDI device.
The integrated 3D audio effects processor uses 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 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 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.
