The SiS968 MuTIOL® 1G Media I/O integrates two PCI Express 1.1 root complex x1 ports, one Universal Serial Bus 2.0 Host Controllers, two Universal Serial Bus 1.1 Host Controllers, the Audio Controller with High-Difinition-Audio interface, the Gigabit Ethernet MAC Controller w/ standard RGMII/MII interface, the IDE Master/Slave controllers, two ports Serial ATA Host Controller, the Serial Peripheral interface (SPI) master controller and SiS MuTIOL® 1G technology. The PCI to LPC Bridge supporting the external trusted platform module 1.2 I/O Advanced Programmable Interrupt Controller, legacy system I/O and legacy power management functionalities are integrated as well.

The SiS968 comprises state of the art Proactive power saving technology that powers on the physical layer, or enables the built-in various host controllers only in the needed basis.

The integrated PCI Express controller complying to PCI express 1.1 specification features two 1-lane ports with module based Hot-Plug capability to support ExpressCard. The PCI express transaction layer supports the event driven clocking scheme that enables the clock whenever needed.  When no transaction activity is scheduled, the transaction layer leads the physical layer into L0s, L1, or L2 low power states. Besides, the entire controller and its corresponding port will be powered down when no device is connected.

The totally eight USB ports can be automatically routed to support a High-speed USB 2.0 device or Full- or Low-speed USB 1.1 device.

The High-Definition-Audio v1.0 supports 8 DMA bus masters working independently and simultaneously (4 Input DMA and 4 Output DMA). Each DMA supports up to 192kHz sample rate, 32-bit sample resolution, and 16 channels. The controller supports 3 separated SDI pins supporting multiple Audio CODECs and Modem CODECs.

The integrated Gigabit Ethernet MAC Controller features an IEEE 802.3 and IEEE 802.3x compliant MAC with external LAN physical layer chip supporting full duplex 10 Base-T, 100 Base-T, 1000 Base-T Ethernet. Additionally, 8 wake-up Frames, Magic Packet and link status changed wake-up function in G1/G2 states are supported.

The integrated IDE Master/Slave controller feature single Independent IDE channels supporting PIO mode 0,1,2,3,4, and Ultra DMA 33/66/100/133. The integrated Serial ATA Host Controller features two SATA ports. It complies with SATA 2.5 specification and supports 3Gb/sec bandwidth for each serial port. The Host Controller also complies with SATA II and AHCI 1.1 specification.

The Serial Peripheral Interface (SPI) is a low-cost 4-pin interface that can be an alternative for system flash on LPC bus. SiS968 integrates a SPI master controller and the vendor can choose either LPC or SPI flash ROM.

SiS968 supports 6 PCI masters and complies with PCI 2.3 specification. It also incorporates the legacy system I/O like: two 8237A compatible DMA controllers, three 8254 compatible programmable 16-bit counters, Real Time clock with 370B CMOS SRAM and two 8259A compatible Interrupt controllers.

The centralized power management module incorporates the ACPI 3.0 compliance functions, the APM 1.2 compliance functions, and the PCI bus power management interface spec. v1.1.

A high bandwidth and mature SiS MuTIOL® 1G technology is incorporated to connect SiS 968 Mobile Media I/O to the SiS MuTIOL® compliance north bridge. The MuTIOL® technology is developed into three layers, namely the Multi-threaded I/O transport Layer delivering 1.2GB bandwidth to connect the embedded DMA Master devices and external PCI masters, the Multi-threaded I/O Packet Layer from/to the Multi-threaded I/O transport layer to/from the MuTIOL® physical layer.
