S/PDIF is a standard audio file transfer format that trans-
fers digital audio signals to a device without having to be
converted first to an analog format. This prevents the
quality of the audio signal from degrading whenever it is
converted to analog. S/PDIF is usually found on digital audio equip-
ment such as a DAT machine or audio processing device. The
S/PDIF connector on the system board sends surround sound and
3D audio signal outputs to amplifiers and speakers and to digital
recording devices like CD recorders.
Serial ATA is a storage interface that is compli-
ant with SATA 1.0 specification. NVIDIA

MCP55PXE and Silicon Image Si I 3132 both support speed of up
to 3Gb/s. Serial ATA improves hard drive performance faster than
the standard parallel ATA whose data transfer rate is 100MB/s.
The NVIDIA
®
MCP55PXE chip allows configuring RAID
on Serial ATA drives. It supports RAID 0, RAID 1, RAID
0+1 and RAID 5.
The Silicon Image Si I 3132 chip allows configuring RAID
on another 2 Serial ATA ports. It supports RAID 0, RAID
1 and RAID 0+1.
The Gigabit MAC (Media Access Control) technology inte-
grated in the NVIDIA
®
MCP55PXE chip, together with
the dual Vitesse VSC8601 Gigabit Phy chips provide fully
functional Gigabit LAN ports.
