Dears,
Could you help to clarify below why DS80PCI800 spec has defined x8/x16 pcie Gen 1/2/3 supporting, but it also defines 8 channel PCie for this part? Thanks
DS80PCI800:x8/x16 PCIE Gen 1/2/3 means that it could realize x8/x16 PCIE with two or four DS80PCI800 pcs。
1. The DS80PCI800 is input equalization, and an output de-emphasis driver.Due to the greater strength of the EQ compared to the De-emphasis driver, we recommend it placed closed to the RX side not the TX side. This placement gives the PCIe preset distance to attenuate and the possibility of over-equalizing the signal is greatly reduced.
2. There is no simulation model of DS80PCI800, but recommend using WENENCH for design and simulation.

请问一下,使用DS80PCI800SQ芯片时,差分对的+/-能否对调使用?
即CPU的TX+能否接到DS80PCI800SQ芯片INB-脚,CPU的TX-能否接到DS80PCI800SQ芯片INB+脚?
