MAX3754

19-2098; Rev 1; 1/02 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 connected port bypass circuits and a repeater that provides clock and data recovery. The quad-PBC allows connection 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 tolerance 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.
