ES1988 General Description

The ES1988 Allegro^TMPCI audio-modem accelerator combines advanced audio and modem functionality in a highly integrated PCI solution. Utilizing one PCI load, the ES1988 provides a two-chip audio-modem solution with digital interface capability to an AC'97 codec in the dock (a.k.a. digital docking). The ES1988 is designed to provide a low-cost, high-performance solution for notebook PC applications.

The high-bandwidth PCI bus and an integrated high-fidelity codec are utilized to deliver advanced PC audio features, such as DirectSound^TMacceleration and HRTF 3D positional audio. The ES1988 implements multistream DirectSound and DirectSound3D acceleration with digital mixing, sample rate conversion, and HRTF 3D filtering for two-speaker 3D positional audio.

The programmable audio signal processor provides support for multiple audio streams. With its built-in DSP core, the ES1988 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 ES1988 maintains full DOS legacy audio compatibility over the standard PCI 2.1 and PCI 2.2 bus. Full DOS game compatibility is ensured through either PC/PCI, distributed DMA (DDMA), or transparent DMA (TDMA).

The ES1988 includes an HSP modem interface via its secondary AC-Link 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 ES1988 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 ES1988 provides a high-quality docking solution through proven AC-link-based digital docking. This is accomplished by using only a five-wire digital connection. The secondary AC'97link (extension 2.1 compliant) of the ES1988 interfaces to a secondary AC'97 codec in the dock to provide high-quality audio in the dock.

The ES1988, which operates at 3.3V digitally and 5.0V in analog, is compliant with the Advanced Power Management (APM) 1.2, Advanced Configuration and Power Interface (ACPI) 1.0, and PCI Power Management Interface (PPMI) 1.0. The ES1988 supports D0, D1, D2, and D3 (hot and cold) power-saving modes for power efficiency when the audio system is both active and idle. CLKRUN# support is also available.

The ES1988 is available in an industry-standard 100-pin low-profile quad flat pack (LQFP) package.
