ES1980 Maestro-3
PCI Audio-Modem Accelerator
Product Brief
DESCRIPTION
The ES1980 Maestro-3 PCI audio-modem accelerator
combines advanced audio and modem functionality in a highly
integrated PCI solution for notebook systems. It uses the highbandwidth PCI bus to deliver advanced PC audio features, such
as HRTF 3D positional audio, DirectSound acceleration and
DVD AC-3 5.1 to 2 speaker virtualization.
The ES1980 implements multistream DirectSound and
DirectSound3D acceleration with digital mixing, sample rate
conversion, and HRTF 3D filtering. The ES1980 maintains full
DOS legacy audio compatibility over the standard PCI 2.1 and
PCI 2.2 buses. The ES1980 is designed for high-performance
consumer multimedia notebook PC applications.
The ES1980 includes a programmable audio signal processor
and provides simultaneous support for multiple audio streams.
With its built-in DSP core, the ES1980 uses its dedicated direct
memory access (DMA) engine to handle complex signal
processing tasks with a bus-mastering PCI interface.
The support functions ensure efficient transfer of audio data
streams to and from system memory buffers, providing a system
solution with maximum performance and minimal host CPU
loading. The architecture enables implementation of
communications over the Internet from multiple sources.
The ES1980 incorporates an HSP modem interface via its ACLink connecting with the ES2828 MC‘97 codec. The MC‘97 is
used as the analog front end for the modem and DAA control.
The V.90 modem runs on the host while the ES1980 serves as
the bidirectional buffer for data transmission and reception. The
modem functions include the standard AT command set, V.42bis
and Group 3 fax.
The ES1980, which operates at 3.3V digitally, is compliant with
the Advanced Power Management (APM) 1.2, Advanced
Configuration and Power Interface (ACPI) 1.1, and PCI Power
Management Interface (PPMI) 1.1. The ES1980 supports D0,
D1, D2, and D3 power-saving modes for power efficiency when
the audio system is both active and idle.
The ES1980 provides a high-quality docking solution and
supports an AC-link based digital docking solution with its
secondary AC‘97 Extension 2.1 compliant interface. CLKRUN#
pin support can be used to stop the PCI interface clock. This
helps achieve the lowest power consumption in D3
hot
state.
The ES1980 provides full DOS game compatibility through three
hardware implementations: PC/PCI, distributed DMA (DDMA),
and transparent DMA (TDMA).
The ES1980 is available in an industry-standard 100-pin lowprofile quad flat pack (LQFP) package.
