2.125gbps, 3.3v Quad-port Bypass With Repeater Integrated Products

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 By Maxim Integrated Products
