MAX3752 General Description

The MAX3752/MAX3753 quad-port bypass ICs are designed for use in the Fibre Channel Arbitrated Loop topology. These devices consist 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/MAX3753 comply 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 phaselocked loop (PLL) provides a frequency lock indication and does not need an external reference clock.

Two pin-compatible versions of the quad PBC are available- the MAX3752 for 2.125Gbps or 1.063Gbps operation, and the MAX3753 for 1.063Gbps operation.

MAX3755 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.
