YMF754
DS-1E
Preliminary
OVERVIEW
YMF754 (DS-1E) is a high performance audio controller for the PCI Bus. DS-1E consists of two separated
functional blocks. One is the PCI Audio block and the other is the Legacy Audio block.
PCI Audio block provides 64-voice XG wavetable synthesizer with reverb and variation by using the software
driver from YAMAHA. It also supports DirectSound hardware accelerator, Downloadable Sound (DLS) and
DirectMusic accelerator.
Legacy Audio block supports FM synthesizer, Sound Blaster Pro, MPU401 UART mode and Joystick function
in order to provide hardware compatibility for numerous PC games on real DOS without any software driver.
DS-1E supports the connection to AC’97 which provides high quality DAC, ADC and analog mixer, and it can
connect two AC’97s. In addition, it supports consumer IEC958, Digital Audio Interface (SPDIF In/Out), to
connect external audio equipment by digital.
In addition to support the same functions of YMF744B (DS-1S), DS-1E adds direct recording function for
SPDIF In, and realizes to use SPDIF In and Zoomed Video Port at the same time. And, DS-1E is featured
with the capability of dramatically reducing power consumption at normal operation.

LOGOS
GENERAL MIDI logo is a trademark of Association of Musical Electronics Industry (AMEI),
and indicates GM system level 1 Compliant.
XG logo is a trademark of YAMAHA Corporation.
SONDIUS-XG logo is a trademark that Stanford University in the United States and
YAMAHA Corporation hold jointly.
Sensaura logo is a trademark of Central Research Laboratories Limited.
1. GM system level 1
GM system level 1 is a world standard format about MIDI synthesizer which provides voice arrangements
and MIDI functions.
2. XG
XG is a format about MIDI synthesizer that is proposed by YAMAHA, and keeps the upper compatibility of
GM system level 1. The good points are the voice arrangements kept extensively, a large number of the
voices, modification of the voices, 3 kinds of effects, and so on.
3. SONDIUS-XG
Products bearing the SONDIUS-XG logo are licensed under patents of Stanford University and YAMAHA
Corporation as listed on <http://www.sondius-xg.com>. The SONDIUS-XG produces acoustic sound
outputs by running a virtual simulation of the actual acoustic instrument operation. Therefore, it provides
much more real-world acoustic sound outputs fundamentally different from the Wavetable sound generator
that simply processes the recorded acoustic sound sources only. The SONDIUS-XG adds the technology
of virtual acoustic sound to the XG format.
4. Sensaura
Sensaura is a technology which provides 3D positional audio and moving effect by HRTF (Head Related
Transfer Function) with 2 speakers or headphone. This feature makes it possible to enjoy invariable and
unchangeable sound feelings in all-positional area covering as wide as 360 degrees.
