5.1.6 Gigabit Ethernet
The conga-TC570 offers a 2.5 Gigabit Ethernet interface via an onboard Intel
®
i225LM/V/IT Phy. The interface supports:
• full-duplex operation at 10/100/1000/2500 Mbps
1,2
• half-duplex operation at 10/100 Mbps
1,2
• Time Sensitive Networking
3,4
Note
1.
The GBE0_LINK# output is not active during a 10 Mb connection. It is only active during a 100 Mb or 1 Gb connection. This is a limitation
of Ethernet Phy since it has only three LED outputs—ACT#, LINK100# and LINK1000#.
2.
The GBE0_LINK# signal is a logic AND of the GBE0_LINK100# and GBE0_LINK1000# signals on the conga-TC570 module.
3.
For real time applications, we recommend to use conga-TC570 industrial variants for Intel
®
TCC/TSN feature.

Not supported in Windows Operating Systems
5.1.7 High Definition Audio
The conga-TC570 provides an HD audio interface on the A–B connector.
5.1.8 LPC Bus
The conga-TC570 offers the LPC bus through an eSPI to LPC bridge. For information about the decoded LPC addresses, see section 9.1.1 “LPC
Bus”.
5.1.9 I²C Bus
The I²C bus is implemented through the congatec board controller 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.
5.1.10 GPIOs
The conga-TC570 offers General Purpose Input/Output signals on the A–B connector. The GPIO signals are controlled by the congatec Board
controller.
