Gigabit Ethernet
The conga-TR3 offers Gigabit Ethernet with the integration of Intel i211 Ethernet Controller. The Ethernet interface consists of 4 pairs of low
voltage differential pair signals designated from GBE0_MDI0± to GBE0_MDI3± 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 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-TR3.

LPC Bus
conga-TR3 offers the Low Pin Count (LPC) bus via the integrated controller hub. The LPC bus corresponds approximately to a serialized ISA
bus yet with a significantly reduced number of signals. Due to the software compatibility to the ISA bus, I/O extensions such as additional serial
ports can be easily implemented on an application specific baseboard using this bus. Many devices are available for this cost-efficient, low-
speed interface designed to support low bandwidth and legacy devices.
The LPC host bus controller supports one master DMA devices. See section 10.1.1 for more information about the LPC Bus.
Note
The conga-TR3 supports optional TPM 1.2/2.0 devices.
6.1.6
I²C Bus Fast Mode
The I²C bus is implemented through the congatec board controller and is accessed through the congatec CGOS driver and API. The controller
provides a fast mode multi-master I²C bus that has maximum I²C bandwidth.
