ETHERNET CONTROLLER OF LS1046A

Ellu24 — Tue, 17 May 2022 23:36:45 GMT

I am designing a hardware using LS1046 and I want to connect ethernet PHY VSC8502-03 , which uses RGMII MAC interface, so that I have to connect that to EC module of processor. My questions are:

1) what should I connect to EC1_GTX_CLK125 pin( any external crystal or clock generator Si 5332 output or any pins from ethernet PHY)

2)If I am not using EC2 , Can I left it unconnected?

3) Should I use synchronous ethernet as specified in VSC8502-03 datasheet, where should I connect RCVRDCLK1,RCVRDCLK2, CLK_SQUELCH_IN. (I have attached VSC8502-03 datasheet. Please find the attachment)

Thanks in advance
