Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX3770 is a 2.125Gbps Fibre Channel repeater IC. The MAX3771 provides a pin-compatible solution for 1.063Gbps Fibre Channel. Both devices are optimized for use in Fibre Channel arbitrated-loop applications and operate from a 3.3V supply.

The MAX3770 is compatible with Fibre Channel jitter tolerance requirements and can recover data signals with up to 0.7 unit interval (UI) jitter. The circuit's fully integrated phase-locked loop (PLL) provides a frequency lock indication and does not need an external reference clock.

The MAX3770 provides low-jitter CML clock and data outputs. To reduce the external parts count, all signal inputs and outputs are internally terminated. The MAX3770/MAX3771 are available in 16-pin QSOP packages.
