Ports
MAX3750/MAX3751
The MAX3750/MAX3751 are +3.3V, Fibre Channel port
bypass ICs that include a high-speed multiplexer and
output buffer stage for hot swapping a storage device.
These devices are optimized for use in a Fibre Channel
arbitrated loop topology.
The MAX3750 has a 2.125Gbps data rate, while the
MAX3751’s data rate is 1.0625Gbps. Total power con-
sumption (including output currents) is low: just 190mW
for the MAX3750 and 180mW for the MAX3751. Low
10ps jitter makes these devices ideal for cascaded
topologies. The output driver circuitry is tolerant of load
mismatches commonly caused by board vias and
inductive connectors. On-chip termination reduces
external part count and simplifies board layout.
