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 MAX3772 are dual-rate (1.0625Gbps and 2.125Gbps) fibre channel repeaters. They are optimized for use in fibre channel arbitrated loop applications and operate from a +3.3V supply. The MAX3772 exceed 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. These repeaters MAX3772 provide low-jitter CML clock and data outputs, and are pin compatible with the MAX3770 repeater (except RATESEL pin and exposed paddle).

The MAX3773/MAX3774 can also be used for impedance transformation between 100Ω (differential) and 150Ω (differential) systems. To reduce the number of external components, all signal inputs and outputs are internally terminated. The MAX3772 are available in 16-pin QSOP-EP packages.
