I need to come up with a design that can interface to some legacy equipment that communicates via a backplane using 10GBASE-KX4
KX4 uses the same physical layer as CX4
CX4 uses the same 4-lane PCS as XAUI
The V-Series Transceiver PHY supports XAUI
As near as I can tell the only difference would be in electrical specifications.
Will the V-Series Transceiver PHY work for KX4?
