The MAX3772MAX3775 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 MAX3772MAX3775 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 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 100 (differential) and 150 (differential) systems. To reduce the number of external components, all signal inputs and outputs are internally terminated. The MAX3772MAX3775 are available in 16-pin QSOP-EP packages.
