Notebook Solution
Product Brief
DESCRIPTION
THE ES1946 PCI
Audio
Drive
solution implements a single-chip
PCI audio solution, providing high-quality audio processing while
maintaining full legacy DOS game compatibility. With a dynamic
range over 80 dB, the ES1946 complies with the Microsoft
PC
98 / PC 99 specifications and meets WHQL audio requirements.
The ES1946 forms a complete audio subsystem on a single chip
for notebook platforms.
The ES1946 operates at 3.3V digital supply and 5V analog
supply. Combined with its built in power management support,
the ES1946 is an ideal audio solution for notebooks.
The ES1946 includes an I
2
S Zoom Video port interface that
allows playback of MPEG audio, using the 16-bit stereo music
DAC, thus reducing the total audio solution chip count.
The ES1946 incorporates a microcontroller,
ESFM
music
synthesizer, 16-bit stereo wave ADC and DAC, 16-bit stereo
music DAC, MPU-401 UART mode serial port, I
2
S Zoom Video
port, serial port interface to external wavetable music
synthesizer, dual game port, hardware master volume control,
direct memory access (DMA) control logic with FIFO, and PCI
bus interface logic. There are three stereo inputs (typically line-
in, CD audio, and auxiliary line) and a mono microphone input.
The ES1946 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 3D
sound environment.
The ES1946 integrates the ESS Technology field-proven
hardware design for DOS game compatibility with hardware FM
synthesis (
ESFM
synthesis) and three methods for legacy audio
control interface: PC/PCI, distributed DMA, and transparent
DMA (TDMA). TDMA requires no sideband signals from PC core
logic chipsets in addition to the standard PCI 2.2 bus. TDMA is
compatible with the Intel
Pentium
, Pentium II
, and
Celeron
chipsets as well as standard PCI add-in cards.
The ES1946 provides a serial EEPROM interface for ease of
programming the subsystem ID and subsystem vendor ID.
The ES1946 can record, compress, and play back voice, sound,
and music with built-in mixer controls. It supports stereo
full-duplex operation for simultaneous record and playback. The
ESFM
synthesizer has extended capabilities within native mode
operation providing superior sound and power-down capabilities.
The ES1946 is compliant with Advanced Power Management
(APM) 1.2, Advanced Configuration and Power Interface (ACPI)
1.0, and PCI Power Management Interface (PPMI) 1.0.
It is available in an industry-standard 100-pin low profile quad flat
pack (LQFP) package.
