Hi,
In my design,I only use the T2080 CPU's SGMII interface for Ethernet,is it necessary to connect the ECn_GTX_CLK125 pin with a 125MHz reference clock?
Thanks!
Solved! Go to Solution.
"When operating in SGMII mode, the ECn_GTX_CLK125 clock is not required for this port." - Section 3.19.9.1 of T2080 datasheet.
When this pin is not used, it is recommended to pull this pin low through a 2-10 kΩ resistor to GND (T2080 Design Checklist, Tables 29 and 30)
Have a great day,
