6.1
Primary Connector Rows A and B
The following subsystems can be found on the primary connector rows A and B.
6.1.1
Serial ATA™ (SATA)
The conga-TC87 provides 4 SATA interfaces (SATA 0-3) externally via the Intel
®
8 Series PCH-LP integrated in the MCP. The SATA ports are
based on Serial ATA Specification, Revision 3.0 and support up to 6.0 Gb/s data transfer rates.
The Intel
®
8 Series PCH-LP featured on the conga-TC87 has one integrated SATA host controller. This controller does not support legacy mode
using I/O space, rather it supports only one mode of operation - AHCI mode using memory space. Hot-plug is also supported when operating
in non-native IDE mode. For more information, refer to section 11 “BIOS Setup Description”.
Note
The conga-TC87 Celeron variants support up to 2 SATA interfaces only.
6.1.2
USB 2.0
The conga-TC87 offers 8 USB 2.0 interfaces on the A-B connector. The EHCI host controller in the PCH supports these interfaces with high-
speed, full-speed and low-speed USB signalling. The controller complies with USB standard 1.1 and 2.0. For more information about how the
USB host controllers are routed, see section 8.5.
6.1.3
High Definition Audio (HDA) Interface
The conga-TC87 provides an interface that supports the connection of HDA audio codecs.
6.1.4
Gigabit Ethernet
The conga-TC87 is equipped with a Gigabit Ethernet Controller that is integrated within the Intel
®
8 Series PCH-LP. This controller is routed
to the onboard Intel
®
l218-LM Phy through the use of the fifth PCI Express lane. 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.
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
