5.1.4

Gigabit Ethernet

The conga-TC175 offers a Gigabit Ethernet interface via an onboard Intel
supports full-duplex operation at 10/100/1000 Mbps and half-duplex operation at 10/100 Mbps.
Note
The GBE0_LINK# output is only active during a 100 megabit or 1 gigabit connection. It is not active during a 10 megabit 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-TC175 module.
5.1.5

LPC Bus

The conga-TC175 offers the LPC (Low Pin Count) bus through the Intel
see section 9.1.1.
5.1.6 I²C Bus Fast Mode
The I²C bus is implemented through the congatec board controller (Texas Instruments Tiva™ TM4E1231H6ZRB) and accessed through the
congatec CGOS driver and API. The controller provides a fast-mode multi-master I²C bus that has the maximum I²C bandwidth.
5.1.7

PCI Express™

The conga-TC175 offers up to 6 PCI Express™ lanes on the A-B connector via the Intel
• up to 8 GT/s (Gen 3) speed
• a 6 x1 link configuration
• an optional 1 x4 + 2 x2 link configuration (requires a special/customized BIOS firmware)
• lane polarity inversion
For the PCI Express lanes on the CD connector, see section 6.2.1.
5.1.8

ExpressCard™

The conga-TC175 supports the implementation of ExpressCards, which requires the dedication of one USB 2.0 port or a x1 PCI Express link for
each ExpressCard used.
