DescriptionYMF754 (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.
YMF754 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.
YMF754 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.
YMF754 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.
