i am working on a design with the LS1043A/46A processor. This processors should be exchangeable at one PCB-Design.
Is it needed to use all 4 SDx_REF_CLKx_P/N as input at the LS1046A or can i use the 2 SD1_REF_CLKx_P/N which the LS1043A provide.
Are the 4 SDx_REF_CLKx_P/N depend on anything while using all 8 SerDes-Lanes ?
SD1_REF_CLK1_P/N is needed for Lane A-B (SerDes1) and SD1_REF_CLK2_P/N is needed for Lane C-D (SerDes1).
Or can i switch the REF_CLK ?
