I am connecting a i.MX6UL processor Ethernet interface to a FPGA through RMII, and the FPGA is converting to 1G Ethernet to the switch. So between the processor and FPGA, the transmission lines have to be terminated. What is the source resistance of the processor? what type and value resistor I should use to terminate the reflection?
Thanks
Hi Nguyen
please check sect.3.8 Impedance signal recommendations i.MX6UL System Development User’s Guide
