LS1021 Ethernet RMII

Question asked by Deepak Naiknavare on Nov 16, 2016

We were trying to communicate LS1021 with TI controller TMS570 over RMII without using a Phy Chip. The TI controller TMS570 datasheet has provided a single reference clock input in RMII mode, whereas the LS1021 controller has 2 clocks for TX and RX in the RMII mode.

How can we connect these two controllers with different number of clocks? Is it a feasible option to these controllers over phyless RMII?


Thanks in Advance!!
