Dual-Rate, 1Gbps/2Gbps Fibre Channel
Quad-Port Bypass ICs with Repeater
General Description
The MAX3754/MAX3755 quad-port bypass circuits
(PBCs) are designed for use in Fibre Channel Arbitrated
Loop applications. Each consists of four serially con-
nected port bypass circuits and a repeater that provides
clock and data recovery. The quad-PBC allows connec-
tion of up to four Fibre Channel L-ports; each can be
enabled or bypassed by individual logic inputs. To
reduce the external parts count, all signal inputs and
outputs have internal termination resistors. The
MAX3754/MAX3755 comply with Fibre Channel jitter tol-
erance requirements and can recover data signals with
up to 0.7 unit intervals (UIs) of high-frequency jitter.
These devices operate from a single +3.3V supply.
