YMF754
DS-1E
OVERVIEW
Preliminary
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鈥?7 which provides high quality DAC, ADC and analog mixer, and it can
connect two AC鈥?7s. 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.
