ORCA ORLI10G Data Sheet
16
The transmit line interface on the ORLI10G can connect to devices that are compliant to either the XSBI standard
or the SFI-4 standard. The major difference for these standards is that for XSBI, the least signicant bit [0] is trans-
ferred rst after serialization by the external MUX device, whereas SFI-4 transmits the most signicant bit rst. In
some cases, bits [15:0] on the ORLI10G should connect to bits [0:15] on the device to which the ORLI10G device
interfaces. An example of this is the PCS IP core in the ORLI10G when the ORLI10G is connected to an XSBI ver-
sion 2.1 device.
It should be noted that IEEE 802.3ae version 3.1 to D3.4 (version D3.4 is the latest draft version of this specica-
tion as of the writing of this data sheet) swaps XSBI so that the most signicant bit is transferred rst, thus requiring
that bits [0:15] on the ORLI10G be connected directly to bits [0:15] on the XSBI device.
