ES1869
AudioDrive® Solution
Data Sheet
DESCRIPTION
The 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 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 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.
