Primary Connector Rows A and B4.1

The following subsystems can be found on the primary connector rows A and B.

Serial ATA™ (SATA)4.1.1

Two Serial ATA150 connections are provided via the Intel

82801FBM (ICH6M). SATA is an enhancement of the parallel ATA therefore offering

higher performance. As a result of this enhancement the traditional restrictions of parallel ATA are overcome with respect to speed and EMI.

SATA starts with a transfer rate of 150 Mbytes/s and can be expanded up to 600 Mbytes/s in order to accommodate future developments. SATA

is completely protocol and software compatible to parallel ATA.

USB 2.04.1.2

The conga-B915 offers 4 UHCI USB host controllers and one EHCI USB host controller provided by the Intel

82801FBM (ICH6M) I/O controller

hub. These controllers comply with USB standard 1.1 and 2.0 and offer a total of 8 USB ports via connector rows A and B. Each port is capable

of supporting USB 1.1 and 2.0 compliant devices. For more information about how the USB host controllers are routed see section 6.6.

Note

The USB controller is a PCI bus device. The BIOS allocates the necessary system resources when conguring the PCI devices.

AC’97 Digital Audio Interface/HDA4.1.3

The conga-B915 provides an interface that supports the connection of AC’97 digital audio codecs as well as HDA audio codecs.

Gigabit Ethernet 4.1.4

The conga-B915 is equipped with a Realtek 8111B/C Gigabit Ethernet Controller. This controller is implemented through the use of the fourth x1

PCI Express link. The Ethernet interface consists of 4 pairs of low voltage differential pair signals designated from GBE0_MD0± to GBE0_MD3±

plus control signals for link activity indicators. These signals can be used to connect to a 10/100/1000 BaseT RJ45 connector with integrated

or external isolation magnetics on the carrier board.
