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

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

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.
