MAX3752

19-1701; Rev 2; 2/01 2.125Gbps, 3.3V Quad-Port Bypass with Repeater General Description 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 applications 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 tolerance 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. o Four High-Speed Data Ports o Meets Fibre Channel Jitter Tolerance Requirements o Large Output Signal Swing (>1000mVp-p) o +3.0V to +3.6V Single-Supply Voltage o On-Chip Termination Resistors Compatible with 75Ω Transmission Lines at All Ports Features MAX3752 Ordering Information PART MAX3752CCM TEMP.
