v Support for full-duplex operation
Single-chip design that includes a RISC processor, fibre
channel protocol manager, PCI/PCI-X DMA controller, and
integrated serializer/deserializer (SERDES) and electrical
transceivers that can auto-negotiate a data rate of 2 Gbps

auto-DMA request, and one auto-DMA response
Integrated 4 KB transmit and 6 KB receive frame buffer
first-in first-out (FIFO) for each data channel
v LC-style connector that supports non-OFC, multimode
fiber-optic cabling using a small form factor (SFF)
fiber-optic transceiver module.
v Total cable length cannot exceed 500 m
5.15 cm x 16.75 cm (2.5 in. x 6.7 in.)
