SerDes

1 lane

One 4-lane SerDes, configurable for combinations of SGMII, QSGMII, PCIe, and SATA interfaces; Several common combinations are:

A、SGMII+QSGMII+PCIe2.0 x1+SATA3.0

B、PCIe3.0 x1+QSGMII+PCIe3.0 x2

C、SGMII+QSGMII+PCIe3.0 x2

D、PCIe3.0 x2+PCIe3.0 x2

E、SGMII+QSGMII+PCIe3.0 x1+PCIe3.0 x1

F、PCIe3.0 x4
