Introduction
This document is intended to provide a complete technical description of the features and
specifications of the Sound Blaster AudioPCI 128 advanced PCI audio cards. The SB
AudioPCI 128 is a PCI audio chipset solution from the Ensoniq division of Creative Technology
Ltd. The Sound Blaster AudioPCI 128 along with an AC97 CODEC offers the next generation
of audio performance in a PC while maintaining full legacy compatibility without old ISA bus
solutions.
The Sound Blaster AudioPCI 128 utilizes the ES1373 PCI audio chip sold in the OEM
market. SB AudioPCI 128 is a PC99 compliant incorporating 3D Audio technology from
Creative which immerses users in 3D audio space. What's more, the ES1373 supports 3D
Positional Audio, Environmental Audio Extension (EAX) for DirectSound and DirectSound3D,
and custom OEM configuration options for CDDA. In addition, Creative’s 3D Audio technology
dramatically improves sound clarity, spatial realism and sound effects, through the minimization of
crosstalk, which will dynamically adjust for monophonic or stereophonic input without user
intervention.
The SB AudioPCI 128 series is fully Plug and Play compliant for ease of use in either DOS,
Windows Millennium, Windows 2000, Windows 95, Windows 98 or Windows NT applications.
SB AudioPCI 128 provides General MIDI compatibility at an attractive price point. It provides
a professional audio solution for today’s newest generation of game, music and entertainment
software. SB AudioPCI 128 also adds support for General Sound drum kit samples and cuttingedge positional 3D audio for true spatial localization of sounds and complies with the Roland
MT-32 standard for wave table audio. It is fully compliant with Multimedia PC Level 3
specifications and with Microsoft Multimedia extensions for Windows.
The CT5801 model of the SB AudioPCI 128 adds the capability of a SPDIF output. This
output is shared with the Line-out, and has an audio sensing circuit to determine if the cable
plugged into the jack is for analog or digital output. Details of the internal connection and SPDIF
cable specifications can be found on pages 12 and 13 of this document.

ES1373 Integrated Audio Chip - General Description
The ES1373 solution is Sound Blaster 16 compatible via emulation, Roland MPU401
compatible via emulation and in full compliance with Multimedia PC Level 3 specifications. In
addition, the ES1373 meets Plug and Play specifications, eliminating any requirement for the user
to select I/O and DMA address settings through hardware or software. The card is automatically
recognized and configured by the Plug and Play host PC during installation
ES1373 is a PCI bus master and slave device that is best understood by looking at the device as
four interactive subsystems: the PCI interface, DMA control, LEGACY functions, and the
CODEC.
The PCI subsystem is a bus master interface that performs the memory accesses to keep the
audio cache buffers full and empties the A/D Converter ( or I2S input) buffer to main memory as
required. The fundamental concept of ES1373 is that the PCI interface controller has a sufficiently
large internal (on-chip) memory cache to meet the memory bandwidth requirements. There is a
sound cache block of 64 bytes for each of the audio channels. It is the responsibility of the DMA
control and the software to keep the buffers full.
All system control registers are accessed via I/O on the PCI bus. The ES1373 uses 16 Long
Words in the I/O space for control registers. All registers are read as Long Words. All registers
are written in byte word or long word format.
The ES1373 essentially implements a 3-channel DMA controller. These virtual DMA
channels are implemented via the CCB, PCI and Serial interface modules. The serial interface
signals the CCB module when a cache transfer is required (playback or record). The CCB module
then signals the PCI module to initiate a bus master data transfer. At this point the CCB and PCI
modules will control the data transfer between host system memory and the ES1373 internal cache.
The LEGACY subsystem is the circuitry required to perform Sound Blaster, OPL-FM and
MPU-401 emulation. Functionally the ES1373 traps on access of the Sound Blaster registers and
then issues the appropriate IRQ or SERR command on the PCI bus. The ES1373 handles the
Legacy DMA function in a similar fashion. The exact functionality of the block cannot be fully
disclosed at this time due to pending patent protection for the application of this technique.
The CODEC controller supports any AC97 compliant CODEC. The functionality of the A/D
and D/A sections are similar to those found in other standard CODECs. The A/D portion of the
CODEC is handled as an independent asynchronous event with a DMA buffer control structure.
Each time the A/D FIFO is filled, a Bus Master request occurs and the FIFO is transferred to main
memory.
The ES1373 also incorporates a SPDIF output. This output is capable of providing stereo
digital audio or compressed AC3 data from a soft DVD decoder.

Power Management
All power management of the system is under software control. The AC97 CODEC and
ES1373 can be powered down separately. Neither chip loses register information when powered
down.
The ES1373 can be power managed by shutting down various sub-systems. The following
blocks can be individually powered down: Joystick, UART, and Serial Interface. Although these
blocks can be individually disabled this will not save an appreciable amount of power. ES1373
can also individually internally shut down the PCI clock and the Crystal input clock. The PCI
clock when shut down will still be active to the PCI and Interrupt/Chip Select modules. The
Crystal clock when shut down will be shut down for all internal modules as well as the output
connection to the AC97 CODEC.
During operation, the ES1373 ASIC will have a typical power dissipation of 150mW. In
power down, the ES1373 ASIC will have a typical power dissipation of 15mW.

CODEC Power Management
The AC97 CODEC is powered down by setting bit 1 (of control bits 7 - 0) in control register
16 (hex) to a zero. The AC97 CODEC control registers are written through the CODEC Interface
block at address 14 (hex).

ES1373 Power Management
As mentioned above, the Joystick, UART, and Serial Interface modules of the ES1373 chip
can be individually powered down. The remaining modules will be in a powered up condition.
The ES1373 modules are powered down by setting bits 6 - 2 (of control bits 31 - 0) to zero. The
ES1373 control register is located in the IRQ and Chip Select Block at address 00 (hex). Note that
the Serial Interface actually has three separate enable bits, one for each of the playback channels
and one for the record channel.
Although these blocks can be individually disabled this will not save an appreciable amount of
power. ES1373 can also individually internally shut down the PCI clock and the Crystal input
clock. The PCI clock when shut down will still be active to the PCI and Interrupt/Chip Select
modules. The Crystal clock when shut down will be shut down for all internal modules as well as
the output connection to the AC97 CODEC.
