4.1
Primary Connector Rows A and B
The following subsystems can be found on the primary connector rows A and B.
4.1.1
Serial ATA™ (SATA)
Two Serial ATA connections are provided via the Intel
®
CG82NM10 (NM10) PCH. These SATA ports are capable of up to 3.0 Gb/s transfer rate.
The conga-TCA provides 2 SATA ports externally.
4.1.2
USB 2.0
The conga-TCA offers one EHCI USB host controller that supports USB high speed signalling and four UHCI host controllers that supports both
low and full speed signalling through Intel
®
CG82NM10 (NM10) PCH. 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 6.5.
4.1.3
High Definition Audio (HDA) Interface
The conga-TCA provides an interface that supports the connection of HDA audio codecs.
4.1.4
Gigabit Ethernet
The conga-TCA offers Gigabit Ethernet with the integration of Realtek RTL8111E Gigabit Ethernet Controller. This controller is implemented
through the use of one PCI Express lane, and runs at a 1.25GHz signalling rate with x1 link width. The Ethernet interface consists of 4 pairs of
low voltage differential pair signals designated from MDI0
±
to MDI3
±
plus three LED 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.
Note
The GBE0_LINK# output is only active during a 100Mbit or 1Gbit connection, it is not active during a 10Mbit connection. This is a limitation
of Ethernet controller since it only has 3 LED outputs, ACT#, LINK100# and LINK1000#. The GBE0_LINK# signal is a logic AND of the
GBE0_LINK100# and GBE0_LINK1000# signals on the conga-TCA module.
