1.2.3.2 SiS961 MuTIOL® Media I/O overview
The SiS961 MuTIOL® Media I/O integrates the Audio Controller with AC 97 Interface
, the Ethernet
MAC, the Dual Universal Serial Bus Host Controllers, the IDE Master/Slave controllers, and the MuTIOL®
Connect to PCI bridge. The PCI to LPC bridge, I/O Advanced Programmable Interrupt Controller, legacy
system I/O, I/O Advanced Programmable Interrupt Controller and legacy power management functionalities
are also integrated. The SiS961 also incorporates an universal interface supporting the asynchronous
inputs/outputs of the X86 compatible microprocessors like PIII, K7 and P4.
The Integrated Audio Controller
features a 6 channels of AC 97 v2.2 compliance audio to present 5.1-
channel Dolby digital material or to generate stereo audio with simultaneous V.90 HSP modem operation.
Besides, 4 separate SDATAIN pins are provided to support multiple audio one modem Codec
maximally, effectuating the realization of 5.1 channel Dolby digital material in theater quality sound. Both
traditional consumer digital audio channel as well as the AC 97 v2.2 compliant consumer digital audio slot are
supported. VRA mode is also associated with both the AC 97 audio link and the traditional consumer digital
audio channel.
The integrated Fast Ethernet MAC
features an IEEE 802.3 and IEEE 802.3x compliant MAC supporting
full duplex 10 Base-T, 100 Base-T Ethernet, or 1Mb/s & 10Mb/s Home networking. 5 wake-up Frames,
Magic Packet and link status change wake-up functions in G1/G2 states are supported. Besides, the integrated
MAC provides a scheme to store the MAC address without the need of an external EEPROM. The 25 MHz
oscillating circuit is integrated so as only an external low cost 25 MHz crystal is needed for the clocking
system.
