12 years ago --- Quote Start --- Hello! I have 5CSXFC6D6F31C6. Can I use PCIe x4 and XAUI simultaneously? --- Quote End --- According to the handbook, I came to the conclusion that answer is no. Device has nine channels. PCIe x4 requires all ( 3 ) channels fron GXB_L0 ( Сh0 - Ch2 ) and 1 channel from GXB_L1 ( Ch3 ). Also, one channel ( Ch4 ) from GXB_L1 is needed as CMU PLL. XAUI requires all ( 3 ) channels from GXB_L2 ( Ch6 - Ch8 ), 1 channel from GXB_L1 ( Ch5 ). And also need channel for CMU PLL. But we have not left channels. Am I wrong?
