The MAX3752 quad-port bypass IC is designed for use
in the Fibre Channel Arbitrated Loop topology. This
device consists of four serially connected port bypass
circuits (PBCs) and a repeater that provides clock and
data recovery (CDR).
The quad-port bypass circuit allows connection of up to
four Fibre Channel L-Ports, which can each be enabled
or bypassed by controlling the PBC select inputs.
Additional quad PBCs can be cascaded for applica-
tions requiring more than four L-Ports. To reduce the
external parts count, all signal inputs and outputs have
internal termination resistors.
The MAX3752 complies with Fibre Channel jitter toler-
ance requirements and can recover data signals with up
to 0.7 unit intervals (UIs) of high-frequency jitter. When
the repeater is not needed, it can be disabled to reduce
power consumption. A fully integrated phase-locked loop
(PLL) provides a frequency lock indication and does not
need an external reference clock.
